See also:JOHN See also:NAPIER (1550-1617)
, Scottish mathematician and inventor of logarithms, was See also:born at Merchiston near See also:Edinburgh in 1550, and was the eighth See also:Napier of Merchiston
.
The first Napier of Merchiston, " See also:Alexander Napare," acquired the Merchiston See also:estate before the See also:year 1438, from See also:- JAMES
- JAMES (Gr. 'IlrKw,l3or, the Heb. Ya`akob or Jacob)
- JAMES (JAMES FRANCIS EDWARD STUART) (1688-1766)

James I. of See also:Scotland
.
He was See also:provost of Edinburgh in 1437, and was otherwise distinguished
.
His eldest son Alexander, who succeeded him in 1454, was provost of Edinburgh in 1455, 1457 and 1469; he was knighted and held various important See also:court offices under successive monarchs; at the See also:- TIME (0. Eng. Lima, cf. Icel. timi, Swed. timme, hour, Dan. time; from the root also seen in " tide," properly the time of between the flow and ebb of the sea, cf. O. Eng. getidan, to happen, " even-tide," &c.; it is not directly related to Lat. tempus)
- TIME, MEASUREMENT OF
- TIME, STANDARD
time of his See also:death in 1473 he was See also:master of the See also:household to James III
.
His son, See also:John Napier of Rusky, the third of Merchiston, belonged to the royal household in the lifetime of his See also:father
.
He also was provost of Edinburgh at various times, and it is a remarkable instance of the esteem in which the lairds of Merchiston were held that three of them in immediate lineal See also:succession repeatedly filled so important an See also:- OFFICE (from Lat. officium, " duty," " service," a shortened form of opifacium, from facere, " to do," and either the stem of opes, " wealth," " aid," or opus, " work ")
office during perhaps the most memorable See also:period in the See also:history of the See also:city
.
He married a See also:great-granddaughter of See also:Duncan, 8th See also:earl of Levenax (or See also:Lennox), and besides this relationship by See also:marriage the Napiers claimed a lineal male cadency from the See also:ancient See also:family of Levenax
.
His eldest son, See also:Archibald Napier of Edinbellic, the See also:fourth of Merchiston, belonged to the See also:house-hold of James IV
.
He fought at See also:Flodden and escaped with his See also:life, but his eldest son Alexander, (fifth of Merchiston) was killed
.
Alexander's eldest son (Alexander, See also:sixth of Merchiston) was born in 1513, and See also:fell at the See also:battle of Pinkie in 1547
.
His eldest son was Archibald, seventh of Merchiston, and the father of John Napier, the subject of this See also:article
.
In 1J49 Archibald Napier, at the See also:early See also:age of about fifteen,married See also:Janet, daughter of See also:Francis See also:Bothwell, and in the following year John Napier was born
.
In the criminal court of Scotland, the earl of See also:Argyll, hereditary See also:justice-See also:general of the See also:kingdom, sometimes presided in See also:person, but more frequently he delegated his functions; and it appears that in 1561 Archibald Napier was appointed one of the justice-deputes
.
In the See also:register of the court, extending over 1563 and .1564, the justice-deputes named are " Archibald Naper of Merchistoune, Alexander See also:Bannatyne, See also:burgess of Edinburgh, James See also:Stirling of Keir and Mr See also:- THOMAS
- THOMAS (c. 1654-1720)
- THOMAS (d. 110o)

- THOMAS, PIERRE (1634-1698)
- THOMAS, SIDNEY GILCHRIST (1850-1885)
- THOMAS, ST
- THOMAS, THEODORE (1835-1905)
- THOMAS, WILLIAM (d. 1554)
Thomas See also:Craig." About 1565 he was knighted at the same time as James Stirling, his colleague, whose daughter John Napier subsequently married
.
In 1582 See also:Sir Archibald was appointed master of the See also:mint in Scotland, with the See also:sole See also:charge of superintending the mines and minerals within the See also:realm, and this office he held till his death in 16o8
.
His first wife died in 1563, and in 1572 he married a See also:cousin, See also:Elizabeth See also:Mowbray, by whom he had three sons, the eldest of whom was named Alexander.'
As already stated, John Napier was born in 155o, the year in which the See also:Reformation in Scotland may be said to have commenced
.
In 1563, the year in which his See also:mother died, he matriculated at St Salvator's See also:College, St See also:Andrews
.
He early became a See also:Protestant See also:champion, and the one extant See also:anecdote of his youth occurs in his address " to the Godly and See also:Christian reader " prefixed to his Plaine See also:Discovery
.
He writes:
" In my See also:tender yeares, and barneage in Sanct-Androis at the Schooles, having, on the one parte, contracted a loving familiaritie with a certaine See also:Gentleman, &c. a Papist; And on the other See also:part, being attentive to the sermons of that worthie See also:man of See also:God, Maister See also:Christopher See also:Goodman, teaching upon the Apocalyps, I was so mooved in admiration, against the blindnes of Papists, that could not most evidently see their seven hilled citie See also:Rome, painted out there so lively by See also:Saint John, as the mother of all spiritual whoredome, that not oncly bursted I out in continual reasoning against my said See also:familiar, but also from thenceforth, I determined with my selfe (by the assistance of Gods spirit) to employ my studie and See also:diligence to See also:search out the remanent mysteries of that See also:holy See also:Book: as to this houre (praised be the Lorde) I have See also:bin doing at al such times as conveniently I might have occasion."
The names of nearly all Napier's classfellows can be traced as becoming determinantes in 1566 and masters of arts in 1568; but his own name does not appear in the lists
.
The necessary inference is that his stay at the university was See also:short, and that only the groundwork of his See also:education was laid there
.
Although there is no See also:direct See also:evidence of the fact, there can be no doubt that he See also:left St Andrews to See also:complete his education abroad, and that he probably studied at the university of See also:Paris, and visited See also:Italy and See also:Germany
.
He did not, however, as has been supposed, spend the best years of his manhood abroad, for he was certainly at See also:home in 1571, when the preliminaries of his marriage were arranged at Merchiston; and in 1572 he married Elizabeth, daughter of Sir James Stirling of Keir
.
About the end of the year 1579 his wife died, leaving him one son, Archibald (who in 1627 was raised to the See also:peerage by the See also:title of See also:Lord Napier), and one daughter, Jane
.
A few years afterwards he married again, his second wife being See also:Agnes, daughter of Sir James
1 The descent of the first Napier of Merchiston has been traced to " Johan le Naper del Counte de Dunbretan," who was one of those who swore fealty to See also:Edward I. in 1296 and defended the See also:castle of Stirling against him in 1304; but there is no authority for this See also:genealogy
.
The See also:legend with regard to the origin of the name Napier was given by Sir Alexander Napier, eldest son of John Napier, in 1625, in these words: " One of the ancient earls of Lennox in Scotland had issue three sons: the eldest, that succeeded him to the earldom of Lennox; the second, whose name was Donald; and the third, named Gilchrist

Chisholm of Cromlix, who survived him
.
By her he had five sons and five daughters
.
In 1588 he was chosen by the See also:presbytery of Edinburgh one of its commissioners to the General See also:Assembly
.
On the 17th of See also:October 2593 a See also:convention of delegates was held at Edinburgh at which a See also:committee was appointed to follow the king and See also:lay before him in a See also:personal interview certain instructions See also:relating to the See also:punishment of the rebellious Popish earls and the safety of the See also:- CHURCH
- CHURCH (according to most authorities derived from the Gr. Kvpcaxov [&wµa], " the Lord's [house]," and common to many Teutonic, Slavonic and other languages under various forms—Scottish kirk, Ger. Kirche, Swed. kirka, Dan. kirke, Russ. tserkov, Buig. cerk

- CHURCH, GEORGE EARL (1835–1910)
- CHURCH, RICHARD WILLIAM (1815–189o)

church
.
This committee consisted of six members, two barons, two ministers and two burgesses—the two barons selected being John Napier of Merchiston and James See also:Maxwell of See also:Calderwood
.
The delegates found the king at See also:Jedburgh, and the See also:mission, which was a dangerous one, was successfully accomplished
.
Shortly afterwards another convention was held at Edinburgh, and it was resolved that the delegates sent to Jedburgh should again meet the king at See also:Linlithgow and repeat their former instructions
.
This was done accordingly, the number of members of the committee being, however, doubled
.
These interviews took See also:place in October 1593, and on the 29th of the following See also:January Napier wrote to the king the See also:letter which forms the See also:dedication of the Plaine Discovery
.
The full title of this first See also:work of Napier's is given below)
.
It was written in See also:English instead of Latin in See also:- ORDER
- ORDER (through Fr. ordre, for earlier ordene, from Lat. ordo, ordinis, rank, service, arrangement; the ultimate source is generally taken to be the root seen in Lat. oriri, rise, arise, begin; cf. " origin ")
- ORDER, HOLY
order that " hereby the See also:simple of this Iland may be instructed "; and the author apologizes for the See also:language and his own mode of expression in the following sentences:
" Whatsoever therfore through hast, is here rudely and in See also:base language set downe, I doubt not to be pardoned thereof by All See also:good men, who, considering the necessitie of this time, will esteem it more meete to make bast to prevent the rising againe of Antichristian darknes within this See also:Band, then to prolong the time in See also:painting of language "; and " I graunt indeede, and am sure, that in the See also:style of wordes and utterance of language, we shall greatlie differ, for therein I do See also:judge my selfe inferiour to all men: so that scarcely in these high matters could I with See also:long deliberation finde wordes to expresse my minde."2
Napier's Plaine Discovery is a serious and laborious work, to which he had devoted years of care and thought
.
In one sense jt may be said to stand to theological literature in Scotland in something of the same position as that occupied by the See also:Canon Mirificus with respect to the scientific literature, for it is the first published See also:original work relating to theological See also:- INTERPRETATION (from Lat. interpretari, to expound, explain, inter pres, an agent, go-between, interpreter; inter, between, and the root pret-, possibly connected with that seen either in Greek 4 p4'ew, to speak, or irpa-rrecv, to do)

Napier lived in the very midst of fiercely contending religious factions; there was but little theological teaching of any See also:kind, and the work related to what were then the leading See also:political and religious questions of the See also:day

See also:German See also:translations were published at See also:Gera in 1611 and at See also:Frankfort in 1605 and 1627
.
The second edition in English appeared at Edinburgh in 1611, and in the See also:preface to it Napier states he intended to have published an edition in Latin soon after the original publication in 1593, but that, as the work had now been made public by the French and Dutch. translations, besides the English editions, and as he was " advertised that our papistical adversaries veer to write larglie against the said editions that are alreadie set out," he defers the Latin edition " till having first seene the adversaries objections, I may insert in the Latin edition an apologie of that which is rightly done, and an amends of whatsoever is amisse." No See also:criticism on the work was published, and there was no Latin edition
.
A third edition appeared at Edinburth in 1645
.
Corresponding to the first two Edinburgh editions, copies were issued bearing the See also:London imprint and See also:dates 1594 and
1611

After the publication of the Plaine Discovery, Napier seems to have occupied himself with the invention of See also:secret See also:instruments of See also:war, for in the See also:- BACON

Bacon collection at See also:Lambeth See also:Palace there is a document, dated the 7th of See also:June 1596 a1ld signed by Napier, giving a See also:list of his inventions for the See also:defence of the See also:country against the anticipated invasion by See also:- PHILIP
- PHILIP (Gr.'FiXtrsro , fond of horses, from dn)^eiv, to love, and limos, horse; Lat. Philip pus, whence e.g. M. H. Ger. Philippes, Dutch Filips, and, with dropping of the final s, It. Filippo, Fr. Philippe, Ger. Philipp, Sp. Felipe)

- PHILIP, KING (c. 1639-1676)

.
The document is entitled " Secrett Inventionis, proffitabill and necessary in theis dayes for defence of this See also:hand, and withstanding of strangers, enemies of 'God's truth and See also:religion," 3 and the inventions consist of (I) a See also:mirror for burning the enemies' See also:ships at any distance, (2) a piece of See also:artillery destroying everything See also:round an arc of a circle, and (3) a round See also:- METAL
- METAL (through Fr. from Lat. metallum, mine, quarry, adapted from Gr. µATaXAov, in the same sense, probably connected with ,ueraAAdv, to search after, explore, µeTa, after, aAAos, other)
metal See also:chariot, so constructed that its occupants could move it rapidly and easily, while firing out through small holes in it
.
It has been asserted (by Sir Thomas See also:Urquhart) that the piece of artillery was actually tried upon a See also:plain in Scotland with complete success, a number of See also:sheep and See also:cattle being destroyed
.
In 1614 appeared the work which in the history of See also:British See also:science can be placed as second only to See also:Newton's Principia

.
This is printed on an ornamental title-See also:page
.
The work is a small-sized See also:quarto, containing fifty-seven pages of explanatory See also:matter and ninety pages of tables
.
The nature of logarithms is explained by reference to the See also:motion of points in a straight See also:line, and the principle upon which they are based is that of the See also:correspondence of a geometrical and an arithmetical See also:series of See also:numbers
.
The table gives the logarithms of sines for every See also:minute to seven figures
.
This work contains the first announcement of logarithms to the See also:world, the first table of logarithms and the first use of the name See also:logarithm, which was invented by Napier
.
In 1617 Napier published his Rabdologia,' a duodecimo of one See also:hundred and fifty-four pages; there is prefixed to it as preface a dedicatory See also:epistle to the high See also:chancellor of Scotland
.
The method which Napier terms " Rabdologia " consists in the use of certain numerating rods for the performance of multiplications and divisions
.
These rods, which were commonly called
" Napier's bones," will be described further on
.
The second method, which he calls the " Promptuarium Multiplicationis " on
See also:account of its being the most expeditious of all for the performance of multiplications, involves the use of a number of lamellae or little plates of metal disposed in a See also:box
.
In an appendix of See also:forty-one pages he gives his third method, " See also:local See also:arithmetic," which is performed on a See also:chess-See also:board, and depends, in principle, on the expression of numbers in the See also:scale of radix 2
.
In the Rabdologia he gives the See also:chronological order of his inventions
.
He speaks of the canon of logarithms as " a me Longo tempore elaboratum." The other three methods he devised for the See also:sake of those who would prefer to work with natural numbers; and he mentions that the promptuary was his latest invention
.
In the preface to the appendix containing the local arithmetic he states that, while devoting all his leisure to the invention of these abbreviations of calculation, and to examining by what methods the toil of calculation might be removed, in addition to the logarithms, rabdologia and promptuary, he had See also:hit upon a certain See also:tabular arithmetic, whereby the more troublesome operations of See also:common arithmetic are performed on an See also:abacus or chess-board, and which may be regarded as an amusement

.
rather than a labour, for, by means of it, addition, subtraction, multiplication, See also:division and even the extraction of roots are accomplished simply by the motion of counters
.
He adds that he has appended it to the Rabdologia, in addition to the promptuary, because he did not wish to See also:bury it in silence nor to publish so small a matter by itself
.
With respect to the calculating rods, he mentions in the dedication that they had already found so much favour as to be almost in common use, and even to have been carried to foreign countries; and that he has been advised to publish his little work relating to their mechanism and use, lest they should be put forth in some one else's name
.
John Napier died on the 4th of See also:April 1617, the same year as that in which the Rabdologia was published
.
His will, which is extant, was signed on the fourth day before his death
.
No particulars are known of his last illness, but it seems likely that death came upon him rather suddenly at last
.
In both the Canonis decriptio and the Rabdologia, however, he makes reference to his See also:ill-See also:health
.
In the dedication of the former he refers to himself as " milli jam morbis pens confecto," and in the " Admonitio " at the end he speaks of his " infirma valetudo "; while in the latter he says he has been obliged to leave the calculation of the new canon of logarithms to others "ob infirmam corporis nostri valetudinem."
It has been usually supposed that John Napier was buried in St See also:Giles's church, Edinburgh, which was certainly the See also:burial-place of some of the family, but Mark Napier (Memoirs, p
.

William See also:Wallace, who, See also:writing in 1832, gives strong reasons for believing that he was buried in the old church of St See also:Cuthbert
.
Professor Wallace's words are
" My authority for this belief is unquestionable
.
It is a See also:Treatise on See also:Trigonometry, by a Scotsman, James See also:Hume of Godscroft, See also:Berwickshire, a place still in See also:possession of the family of Hume
.
The work in question, which is rare, was printed at Paris, and has the date-1636 on the title-page, but the royal See also:privilege which secured it to the author is dated in October 1635, and it may have been written several years earlier
.
In his treatise (page 116) Hume says, speaking of logarithms, ` L'inuenteur estoit un Seigneur de grande See also:condition, et duquel la posterite est aujourd'huy en possession de grandes dignitez dans le royaume, qui extant sur l'age, et grandement trauaille See also:des gouttes ne pouvait faire autre See also:chose que de s'adonner aux sciences, et principalment aux mathematiques et a la logistique, a quoy it se plaisoit infiniment, et auec estrange See also:peine, a construict ses Tables des Logarymes, imprimees a Edinbourg en See also:Fan 1614
..
Il mourut Fan 1616, et fut enterre hors la See also:Porte Occidentale d'Edinbourg, dans 1'Eglise de Sainct Cudbert.' "
There can be no doubt that Napier's devotion to See also:mathematics was not due to old age and the See also:gout, and that he died in 16r7 and not in 1616; still these sentences were written within eighteen years of Napier's death, and their author seems to have had some See also:special See also:sources of See also:information
.
Additional See also:probability is given to Hume's assertion by the fact that Merchiston is situated in St Cuthbert's See also:parish
.
It is nowhere else recorded that Napier suffered from the gout
.
It has been stated that Napier's mathematical pursuits led him to dissipate his means
.
This is not so, for his will (Memoirs, p
.
427) shows that besides his large estates he left a considerable amount of personal See also:property
.

.
Briggs was greatly excited by Napier's invention and visited him at Merchiston in 1615, staying with him a whole See also:month; he repeated his visit in 1616 and, as he states, " would have been glad to make him a third visit if it had pleased God to spare him so long." The logarithms introduced by Napier in the Descriptio are not the same as those now in common use, nor even the same as those now called Napierian or hyperbolic logarithms
.
The change from the original logarithms to common or decimal logarithms was made by both Napier and Briggs, and the first tables of decimal logarithms were calculated by
Briggs, who published a small table, extending to See also:I000, in 1617, and a large work, Arithmetica Logarithmica,l containing
logarithms of numbers to 30,000 and from 90,000 to 100,000, in 1624
.
(See LOGARITHM.)
Napier's Descriptio of 1614 contains no explanation of the manner in which he had calculated his table
.
This account he kept back, as he himself states, in order to see from the reception met with by the Descriptio, whether it would be acceptable
.
Though written before the Descriptio it had not been prepared for See also:press at the time of his death, but was published by his son Robert in 1619 under the title Mirifici Logarithmorum Canonis Constructio .2 In this treatise (which was written before Napier had invented the name logarithm) logarithms are called " artificial numbers."
The different editions of the Descriptio and Constructio, as well as the reception of logarithms on the See also:continent of See also:Europe, and especially by See also:Kepler, whose admiration of the invention almost equalled that of Briggs, belong to the history of logarithms (q.v.)
.
It may, however, be mentioned here that an English translation of the Constructio of 1619 was published by W

See also:Macdonald at Edinburgh in 1889, and that there is appended to this edition a complete See also:catalogue of all Napier's writings, and their various editions and translations, English and foreign, all the works being carefully collated, and references being added to the various public See also:libraries in which they are to be found
.
Napier's priority in the publication of the logarithms is unquestioned and only one other contemporary mathematician seems to have conceived the See also:idea on which they depend
.
There is no anticipation or hint to be found in previous writers,s and it is very remarkable that a discovery or invention which was to exert so important and far-reaching an See also:influence on See also:
