FEAST OF See also:TABERNACLES , the autumn festival of the Israelites, beginning on the 15th of Tishri and celebrated by residing for the seven succeeding days in rustic booths (Heb . Sukkoth, in the See also:Vulgate Tabernacula, whence the See also:English name of the feast) . Among the See also:Hebrews it was the third and See also:chief of the three See also:annual See also:pilgrimage festivals connected respectively with the harvesting ofthebarley (See also:Passover), of See also:wheat (See also:Pentecost), and of the See also:vine (See also:Tabernacles) . Hence it is referred to as " the Feast " See also:par excellence (Heb . Hehag, cf . Arab . See also:Hajj) even as See also:late as 2 Chron. vii . 9 . Being of the nature of a pilgrimage feast the booths were temporary erections for the See also:accommodation of the pilgrims . But in See also:early Jewish tradition, in both Yahvist and Elohist See also:sources of the See also:Pentateuch (Exod. xxxiv . 22, See also:xxiii . 16) it is called simply the See also:Harvest Feast (A.V . " Feast of Ingathering ") and is to be observed " at the end of the See also:year," i.e. of the agricultural year . In Deut. xvi . 13 seq., it is termed the Feast of Tabernacles and is to be kept seven days after the produce of the threshing-See also:floor and winepress has been gathered in . In the Holiness See also:Code (Lev. xxiii . 39) it is to be kept for seven days after the first, the first of which is to be " a See also:sabbath," and the eighth " a sabbath " (possibly originally a lunar See also:quarter-See also:day): branches of four trees are to be taken . In the Priestly Code (Lev. xxiii . 33 seq.; Num. See also:xxix . 12–38) the first and eighth day are to be days of See also:holy See also:assembly, and in the latter passage elaborate details are given of the sacrifices to be presented, including a See also:series of bullocks, thirteen on the first day, twelve on the next, and so on down to seven on the seventh day . Only one is to be sacrificed on the concluding feast (Heb. rt1yereth) of the eighth day . The higher See also:criticism See also:sees, in these successive enactments of the various codes included in the Pentateuch (q.v.), a development in the See also:character of the festival . At first held at any of the See also:local shrines, such as See also:Gilgal, See also:Bethel, See also:Shiloh, as well as See also:Jerusalem, it was held at an indefinite date during the harvest in the fall of the year . Then with the concentration of the cultus at Jerusalem represented by See also:Deuteronomy, the celebration was restricted to the Judean See also:capital, and its duration fixed at seven days, though its date was still See also:left indeterminate . This was fixed in the Priestly Code at the 15th of the seventh See also:month, and an eighth day of See also:solemn assembly added after the return from the See also:exile . Against this hypothetical reconstruction is the fact that See also:Solomon appears to have selected the occasion of the feast for the See also:dedication of the See also:temple, and that it lasted, even in histime, seven days (1 See also:Kings viii . 2, 65) . See also:Jeroboam arranged for a similar feast in the See also:northern See also:kingdom on the 15th day of the eighth month, " like unto the feast in See also:Judah" (ibid. xii . 32) . The determination of a fixed date must therefore have been much earlier than Deuteronomy or the alleged See also:period of the Priestly Code . A pilgrimage feast must be fixed in date to ensure the simultaneous presence of the pilgrims . There are, besides, seeming references to the feast in the early prophets, as See also:Hosea xii . 9, See also:Amos v . 21, as well as in See also:Isaiah ix . 2 (Heb.) . The concluding feast does not seem to refer to tabernacles per se, but to be distinct from it, as is shown by the break in the descending series of the sacrifices of bullocks as given in See also:Numbers .
In Jewish practice the concluding feast is not held in booths, and See also:Maimonides (Moreh, 42) suggests that its See also:object was to give opportunity for final proceedings in assembly halls
.
The existence, therefore, of much variation in the practice of the festival in historic times is scarcely proved by the seeming See also:variations of the enactments concerning it in the Pentateuch
.
It is possible, however, that there may have been See also:differences of See also:custom in the carrying out of the feast
.
In Neh. xiii

40, though in Jewish tradition the latter passage was taken to refer to the Lulab, or a See also:combination of twigs of See also:willow and See also:myrtle, with a See also:palm See also:branch, which, together with a citron, are held in the See also:hand during processions in the See also:synagogue
.
The See also:Sadducees and Karaites did not carry these in their hand, but used them as decorations of the booths
.
In the second temple there was a See also:water See also:libation every See also:morning of the festival, and on the evening of the first day the See also:great See also:golden See also:candelabrum was lit up and the men danced a See also:torch See also:dance around it (Mishnah, Sukkah, v

.
It is reported by See also:Josephus that, when See also: 27), is uncertain . All nations have similar harvest homes, especially with reference to the vintage feasts; as, for instance, the Athenian Oschophoria . The Syrians celebrated every three years a " See also:Booth Festival." At the See also:Hindu Festival of Dasara, which lasted nine days from the new See also:moon of See also:October, tents made of See also:canvas or booths made of branches were erected in front of the temples . The Spartans had a nine days' festival termed See also:Carnea, during which they dwelt in pavilions and tents in memory of their old See also:camp See also:life (See also:Athenaeus, iv . 19) . The Feast of Tabernacles is one of the few Jewish festivals described in classical writers . See also:Plutarch (See also:Symposium iv., vi . 2) compares Tabernacles with the Bacchic See also:rites . It was pre-eminently the period of exultation in See also:ancient Jewish rite, and the Mishnah declares that " He who has not seen the joy of the libations of Tabernacles has never in his life witnessed joy." So much importance was attributed to this festival that it was chosen as the occasion on which the See also:Law should be recited during the sabbatical year (Deut. xxxi . 9–12), and the Messianic See also:vision of See also:Zechariah xiv . 16 sees the remnant of all the nations coming up to Jerusalem to See also:worship the See also:Lord of Hosts, and to keep the Feast of Tabernacles . In later Jewish custom the one-year See also:cycle of See also:reading of sections from the Pentateuch ends on the concluding day of Tabernacles, which is therefore known as the Rejoicing of the Law (Simltat Torah) . The custom of dwelling, for See also:part of the day at least, in booths, is still kept up by orthodox See also:Jews, who have temporary huts covered with branches erected in their courtyards, and those who are not in See also:possession of a See also:house with a backyard often go to pathetic extremes in See also:order to fulfil the law by making holes in See also:roofs, across which branches are placed . U . JA.) When the table became a fixed and permanent piece of See also:furniture the word " See also:board, " which had See also:long connoted it, See also:fell into disuse See also:save in an allusive sense, and its See also:place was taken by such phrases as " joyned table " and " framed table"—that is, jointed or framed together by a joiner; sometimes See also:people spoke of a " See also:standing " or " dormant " table . They were most frequently oblong, some two feet or two feet six inches wide, and the guests sat with their backs to the See also:wall, the other See also:side of the table being left See also:free for service . Sometimes they were used as side-tables, or furnished with a See also:cupboard beneath the board; they were supported on quadrangular legs or massive ends and feet full of See also:Gothic feeling, and were. several inches higher than the dining-table of the loth See also:century . Heavy stretchers or See also:foot-rails were fixed See also:close to the floor—for the avoidance, no doubt, of See also:draughts . See also:Oak was the usual material, but See also:elm, See also:cherry and other See also:woods were sometimes used . Soon the legs became bulbous, and were gadrooned or otherwise ornamented, and the See also:frame began to be carved . The introduction, before the 16th century closed, of the "See also:drawing table" marked the rapidity with which this piece of furniture was See also:developed . This was the forerunner of the " extending dining-table." Of the three leaves of which these tables were composed two were below the other; they See also:drew out and were supported by brackets, while the slab proper dropped to the same level . Somewhat later legs became excessively bulbous; 1 For mathematical tables see next See also:article . This use of the word comes from the See also:analogy of the laying out of See also:objects on an See also:ordinary table.this ugly See also:form gave place soon after the See also:middle of the 17th century to See also:baluster-shaped legs .
Hitherto tables had, generally speaking, been large and massive—little in the nature of what is now called the " occasional table " seems to have been provided until some years after the Restoration
.
About that See also:time small tables of varying sizes and shapes, but still of substantial See also:weight, began to be made; many of them were flap-tables, which took up little See also:room when they were not in use
.
These, however, had been known at an earlier date

Then came the See also:Empire period; the See also:taper was replaced by the round leg, rosewood See also:grew commoner, and See also:brass mountings the See also:rule

to form a table of See also:prime numbers the See also:process is theoretically See also:simple and rapid, for we have only to range all the numbers in a See also:line and strike out every second number beginning from 2, every third beginning from 3, and so on, those that remain being primes
.
Even when the See also:tabular results are constructed separately, the method of differences or other methods connecting together different tabular results may afford valuable verifications

By having recourse to tables not only does the computer save time and labour, but he also obtains the certainty of accuracy
.
The invention of logarithms in 1614, followed immediately by the calculation of logarithmic tables, revolutionized all the methods of calculation; and the See also:original work performed by See also: Nearly all See also:modern tables are stereotyped, and in giving their titles the accompanying date is either that of the original stereotyping or of the lirage in question . In tables that have passed through many See also:editions the date given is that of the edition described . A much See also:fuller account of general tables published previously to 1872, by the present writer, is contained in the See also:British Association See also:Report for 1873, pp . 1-175 . Tables of Divisors (See also:Factor Tables) and Tables of Primes.—The existing factor tables extend to 10,000,000 . In 1811 L . Chernac published at See also:Deventer his Cribrum arithmeticum, which gives all the prime divisors of every number not divisible by 2, 3, or 5 up to 1,020,000 . In 1814–1817 J . C . See also:Burckhardt published at See also:Paris his Tables See also:des diviseurs, giving the least divisor of every number not divisible by 2, 3, or 5 up to 3,036,000 . The second million was issued in 1814, the third in 1816, and the first in 1817 . The corresponding tables for the seventh, eighth, and ninth millions were calculated by Z .
Dase and issued at See also:Hamburg in 1862, 1863, and 1865
.
Dase died suddenly in 1861 during the progress of the work, and it was completed by H

Rosenberg
.
Dase's calculation was performed at the instigation of See also:Gauss, and he began at 6,00o,000 because the See also:Berlin See also:Academy was in possession of a See also:manuscript presented by Crelle extending Burckhardt's tables from 3,000,000 to 6,000,000
.
This manuscript was found on examination to be so inaccurate that the publication was not desirable, and accordingly the three intervening millions were calculated and published by See also: The first three millions were issued separately, and also See also:bound in one See also:volume, but the other six millions are all See also:separate . Burckhardt began the publication of his tables with the second million instead of the first, as Chernac's factor table for the first million was already in existence . Burckhardt's first million does not supersede Chernac's, as the latter gives all the prime divisors of numbers not divisible by 2, 3, or 5 up to 1,020,000 . It occupies 1020 pages, and Burckhardt found it very accurate; he detected only See also:thirty-eight errors, of which nine were due to the author, the remaining twenty-nine having been caused by the slipping of type in the See also:printing . The errata thus discovered are given in Burckhardt's first million . Other errata are contained in See also:Allan See also:Cunningham's paper referred to below . Burckhardt gives but a very brief account of the method by which he constructed his table; and the introduction to Dase's millions merely consists of Gauss's See also:letter suggesting their construction . The Introduction to the Fourth Million (pp . 52) contains a full account of the method of construction and a See also:history of factor tables, with a bibliography of writings on the subject . The Introduction (pp . 103) to the Sixth Million contains an enumeration of primes and a great number of tables relating to the See also:distribution of primes in the whole nine millions, portions of which had been published in the See also:Cambridge Philosophical Proceedings and elsewhere . A See also:complete See also:list of errors in the nine millions was published by J . P . See also:Gram (Acta mathematica, 1893, 17, p . 310) . These errors, 141 in number, and which affect principally the second, third, eighth, and ninth millions, should be carefully corrected in all the tables . In 1909 the See also:Carnegie Institution of See also:Washington published a factor table by Prof . D . N . Lehmer which gives the least factor of all numbers not divisible by 2, 3, 5, or 7, up to ten millions . This table which covers a range of 21,000 numbers on a single page, was reproduced by See also:photography from a type-written copy of the author's original manuscript . The introduction contains a list of errata in the nine millions previously published, completely confirming Gram's list . The factor tables which have just been described greatly exceed both in extent and accuracy any others of the same See also:kind, the largest of which only reaches 408,000 . This is the limit of Anton Felkel's Tafel alter einfachen Factoren (See also:Vienna, 1776), a remark-able and extremely rare book,' nearly all the copies having been destroyed . Georg See also:Vega (Tabulae, 1797) gave a table showing all the divisors of numbers not divisible by 2, 3, or 5 up to 102,000, followed by a list of primes from 102,000 to 400,313 . In the earlier editions of this work there are several errors in the list, but these are no doubt corrected in J . A . Hiilsse's edition (184o) . J . Salomon (Vienna, 1827) gives the least divisor of all numbers not divisible by 2, 3, or 5, up to 102,011, and B . See also:Goldberg (Primzahlen and Factoren-Tafeln, See also:Leipzig, 1862) gives all factors of numbers not divisible by 2, 3, or 5 up to 251,650 . H . G . Kohler (Logarithmisch-trigonometrisches Handbuch, 1848 and subsequent editions) gives all factors of numbers not prime or divisible by 2, 3, 5, or 11 up to 21,525 . See also:Peter See also:Barlow (Tables, 1814) and F . Schaller (Primzahlen-Tafel, See also:Weimar, 1855) give all factors of all numbers up to so,000 . Barlow's work also contains a list of primes up to 100,103 . Both the factor table and the list of primes are omitted in the stereotyped (1840) reprint . Full lists of errata in Chernac (1811), Barlow (1814), Hiilsse's Vega (1840), Kohler (1848), Schaller (1855), and Goldberg (1862) are contained in a paper by Allan Cunningham (See also:Mess. of Math., 1904, 34, p . 24; 1905, 35, p . 24) . V . A . Le Besgue (Tables diverses pour la decomposition des nombres, Paris, 1864) gives in a table of twenty pages, the least factor of numbers not divisible by 2, 3, or 5 up to 115,500 . In See also:Rees's Cyclopaedia (1819), article " Prime Numbers," there is a list of primes to 217,219 arranged in decades . The Fourth Million (1879) contains a list of primes up to 30,341 .

See also the papers on factorizations of high numbers referred to under Tables relating to the Theory of Number; . The Vienna Academy possesses the manuscript of an immense factor table extending to 100,000,000, constructed many years ago by J . P . Kulik (1793–1863) (see Ency. math . Wiss., 1900-1904, i . 952, and Lehmer's Factor Table, p. ix.) . Multiplication Tables.—A multiplication table is usually of See also:double entry, the two arguments being the two factors; when so arranged it is frequently called a See also:Pythagorean table . The largest and most useful work is A . L . Crelle's Rechentafeln (Bremiker's edition, 1857, stereotyped; many subsequent editions with See also:German, See also:French, and English See also:title-pages), which gives in one volume all the products up to I000Xwoo, so arranged that all the multiples of any one number appear on the same page . The original edition was publishect in 1820 and consisted of two thick See also:octavo volumes . The second (stereotyped) edition is a convenient See also:folio volume of 450 pages.' In 1908 an entirely new edition, edited by O . Seeliger, was published in which the multiples of to, 20, ..., 990 (omitted in previous editions) are included . This adds 5o pages to the volume, but removes what has been a great See also:drawback to the use of the tables . Other improvements are that the tables are divided off horizontally and vertically by lines and spaces, and that, for calculations in which the last two figures are rejected, a See also:mark has been placed to show when the last figure retained should be increased . Two other tables of the same extent (woo X woo), but more condensed in arrangement, are H . C . See also:Schmidt's Zahlenbuch (See also:Aschersleben, 1896), and A . Henselin's Rechentafel (Berlin, 1897) . An See also:anonymous table, published at See also:Oldenburg in 1860, gives products up to 500X509, and M . Cordier, Le Multiplicateur de trois cents carres (Paris, 1872), gives a multiplication table to 300X300 (intended for commercial use) . In both these See also:works the product is printed in full . The four following tables are for the multiplication of a number by a single See also:digit . (I) A . L . Crelle, Erleichterungstafel fiir jeden, der zu rechnen See also:hat (Berlin, 1836), a work extending to woo pages, gives the product of a number of seven figures by a single digit, by means of a double operation of entry . Each page is divided into two tables: for example, to multiply 9382477 by 7 we turn to page 825, and enter the right-hand table at line 77, See also:column 7, where we find 77339; we then enter the left-hand table on the same page at line 93, column 7, and find 656, so that the product required is 65677339 . (2) C . A . See also:Bretschneider, Produktentafel (Hamburg and See also:Gotha, 1841), is somewhat similar to Crelle's table, but smaller, the number of figures in the multiplicand being five instead of seven . (3) In S . L . Laundy, A Table of Products (London, 1865), the product of any five-figure number by a single digit is given by a double arrangement . The extent of the table is the same as that of Bretschneider's, as also is the principle, but the arrangement is different, Laundy's table occupying only to pages and Bretschneider's 99 pages . (4) G . Diakow's Multiplikations-Tabelle (St See also:Petersburg, 1897) is of the same extent as Bretschneider's table but occupies woo pages . Among tables extending to IooXl000 (i.e. giving the products of two figures by three) may he mentioned C . A . Mailer's Multiplications-Tabellen (See also:Karlsruhe, 1891) . The tables of L . See also:Zimmermann (Rechentafeln, Liebenwerda, 1896) and J . Riem (Rechentabellen fiir Multiplication, See also:Basel, 1897) extend to IooXio,000 . In a folio volume of 500 pages J . See also:Peters (Rechentafeln See also:fur Multiplikation and See also:Division mit e'n- bis viersteliigen Zahlen, Berlin, 1909) gives products of four figures by two . The entry is by the last three figures of the multiplicand, and there are 2000 products on each page .
Among earlier tables, the See also:interest of which is mainly See also:historical, mention may be made of C

Gruson's Grosses Einmaleins von Eins bis Hunderttausend (Berlin, 1799)—a table of products up to 9 X10,000
.
The author's intention was to extend it to 100,000, but only the first part was published
.
In this book there is no condensation or double arrangement; the pages are very large, each containing 125 lines
.
Quarter-Squares.—Multiplication may be performed by means of a table of single entry in the manner indicated by the See also:formula-
ab = 1(a +b)2-4 (a-b)2
.
Only one other multiplication table of the same extent as Crelle's had appeared previously, viz
.
Herwart von Hohenburg's Tabulae arithmeticaa irporGacaipsos n universales (See also:Munich, 1610), a huge folio volume of more than a thousand pages
.
It appears from a See also:correspondence between See also:Kepler and von Hohenburg, which took place at the end of 1608, that the latter used his table when in manuscript for the performance of multiplications in general, and that the occurrence of the word prosthaphaeresis on the title is due to Kepler, who pointed out that by means of the table spherical triangles could be solved more easily than by Wittich's prosthaphaeresis
.
The invention of logarithms four years later afforded another means of performing multiplications, and von Hohenburg's work never became generally known
.
