[The ‘Thesaurus Mathematicus’], the ‘Opus Palatinum,’and Vlacq’s ‘Arithmetica Logarithmica,’ 1628

and ‘Trigonometria Artificialis,’ 1633,may be said to be the four fundamental tables

of the mathematical sciences.

Glaisher, 1873 [24, p. 45]

1 Vlacq’s Arithmetica logarithmica (1625–1628)

Adriaan Vlacq (ca. 1600–1667) came to be involved in the publication of tables of loga-rithms through Ezechiel de Decker (ca. 1603–ca. 1647), a Dutch surveyor and teacher ofmathematics.

De Decker had the idea of translating a number of works by Napier and others,but De Decker neither had a command of Latin, nor presumably the money to publishthe books. As Vlacq knew Latin and had money, they entered a contract to publish anumber of works. Two books were published in 1626, the “Eerste deel van de nieuwetelkonst” [10], containing several translations, and the Nieuwe telkonst [11], containing ashortened version of Briggs’ Arithmetica logarithmica, as well as a translation of Gunter’stable of logarithms of sines and tangents. Both books had as their sole author De Deckerwho announced another more complete work, the Tweede deel , which for a long time hadseemed never to have been published.

The Tweede deel [12] was published in 1627, but only two or three copies of it seemto have survived, for reasons which are still not totally clear, and that we have tried toexpose in our study of Vlacq’s 1628 table [41]. It was only in 1920 that the Tweede deelwas really rediscovered. It contained a table of the logarithms from 1 to 100000 to 10decimal places.

The same table was republished by Vlacq in 1628, with Briggs’ introduction to hisArithmetica logarithmica [6], and without any mention of De Decker’s work or involve-ment [52]. Between 1628 and 1920, Vlacq was therefore considered as the author of awork of which he was only a participant, albeit one that did a great share of work.

The work on the Arithmetica logarithmica, of which he was actually the publisher(with Rammazeyn being the printer), apparently led Vlacq to learn enough mathematicsto compute tables by himself.

2 Vlacq’s first trigonometric table (1628)

A large part of De Decker’s 1627 table was computed by Vlacq, as acknowledged by DeDecker in his preface [12]. In 1628, Vlacq added a table at the end of the Arithmeticalogarithmica, containing a canon of logarithms of trigonometric functions. This canongave the logarithms of the six trigonometric functions to 10 places for every minute ofthe quadrant. Like Gunter’s table, this table actually gave the values of 10 + log sin,10 + log cos, 10 + log tan, and 10 + log cot. It does not, however, use a radius of 1011 asclaimed by Vlacq and copied by others [37, p. 156].

3

This table extended Gunter’s table which gave the logarithms of sines and tangentsto 7 places for every minute [27] and it prefigured Vlacq’s 1633 Trigonometria artifi-cialis [53]. It was presumably computed by Vlacq who only needed to compute thelogarithms of sines from 0◦ to 45◦. Vlacq explained his method of construction in thepreface of the Arithmetica logarithmica. He actually based himself on Pitiscus’ Thesaurusmathematicus [38], computing logarithms of known sines using the radix method.1

If log sinα has been computed for α ≥ 45◦, then we can use log sinα = log sin 2α +log sin 30◦ − log sin(90◦ − α) for α < 45◦ and the logarithms of tangents and secants canbe obtained with

log tanα = log sinα− log sin(90◦ − α)

log secα = − log sin(90◦ − α)

Such a method does however lead to an accumulation of errors. Delambre writesthat sometimes eight logarithms were used to compute a new one, which causes the lastdecimal to be sometimes incorrect [13, vol. 2, p. 421].

3 The Trigonometria artificialis (1633)

Immediately after the completion of the Arithmetica logarithmica (1628), Vlacq musthave planned to extend this table and construct a more complete table. This was tobe the Trigonometria artificialis. This table, completed in 1630 [21, p. 298], was onlypublished in 1633. It gave the logarithms of the six trigonometric functions to 10 placesevery 10 seconds of the quadrant.

The Trigonometria artificialis also contains the logarithms of numbers 1–20000 takenfrom Vlacq’s Arithmetica logarithmica (1628).

3.1 The introduction to the tables

At about the same time as Vlacq, Briggs’ Trigonometria britannica [7] was completedand also printed at Gouda in 1633 by the same printer.

Given what Vlacq did with the Arithmetica logarithmica, it is not surprising to learnthat he also copied almost 50 pages from the Trigonometria britannica without givingany credit to Briggs [37, p. 159]. But, as shown below, Vlacq did not copy Briggs’ tables.

In any case, the identity of the introductions may explain why, according to Miller [37,p. 159], there are two slightly different title pages, one where the borrowing of Trigono-metria britannica is acknowledged, and another where it is not.

3.2 The sexagesimal division

Briggs’Trigonometria britannica (1633) [7] uses a centesimal division of the degrees, andsince this is Briggs’ first and only trigonometric canon, there was no prior table by

1This was also observed by Delambre [13, vol. 2, p. 421], Glaisher [23, pp. 442–443] and Wolf [57,vol. 1, pp. 169–175].

4

him with a similar division. It is likely that Vlacq took the traditional direction forthe Trigonometria artificialis (1633) [53], probably without knowing that Briggs woulddivide the degrees centesimally. We can theorize that Vlacq would have switched tothe centesimal division, had he known of Briggs’ projects soon enough, but Vlacq hadprobably learned of it too late for undertaking such a major change in the division of theangles.

Glaisher considered that if Vlacq had done the same in his Trigonometria artificialis(1633) [53], the switch to a centesimal division might have been easier [21, pp. 301–302],because all the later tables eventually were based on Vlacq’s tables. He was the lastperson who really could have made the switch to a centesimal division possible.

3.3 The construction of the tables

As far as we are aware, there have been very few investigations into the methods employedby Vlacq to construct his trigonometric tables. Only two articles shed a light in this area,namely Gauss’ remarks published in 1851 [18] and Glaisher’s further researches spurredby Gauss and published in 1873 [23].

Gauss had a closer look at the trigonometric part of Vega’s Thesaurus logarithmorumcompletus [51]. These tables reproduce Vlacq’s tables from 2◦ to 45◦, giving the loga-rithms of the trigonometric functions every 10 seconds. From 0◦ to 2◦, the functions wereinterpolated for every second by Lieutenant Dorfmund, under Vega’s direction.

Gauss noticed “that the tabular results in the sine column were almost without ex-ception equal to the sum of the corresponding tabular results in the cosine and tangentcolumns.” [23, p. 440] However, if each value had been computed independently and cor-rectly rounded, this relation should only hold on average in three cases out of four.2 Forinstance, considering the equalities a+ b = c, rounding a, b and c will break the relationin certain cases: 0.13 + 0.24 = 0.37, but 0.1 + 0.2 6= 0.4.

Moreover, Gauss observed that Vlacq’s logarithmic tangents are the most inaccurate,and that the logarithmic cosines are more accurate than the logarithmic sines. From this,Gauss concluded that the logarithmic tangents had been obtained from the logarithmicsines and cosines. Gauss thought that the logarithmic cosines were more accurate becausethe interpolation was simpler for them.

In fact, Vlacq explained in his preface how the tables were constructed [23, p. 441],but Gauss failed to notice it, perhaps because he did not have access to Vlacq’s originalvolume and only to Vega’s Thesaurus .

Vlacq first computed the logarithms of the cosines from 0◦ to 45◦. This was done usingthe sines given by Rheticus in the Opus palatinum (1596) [40] where they are tabulatedto 10 decimal places every 10 seconds, the same step as the one used by Vlacq. There are45× 60× 6 = 16200 logarithms and they could have been computed using Briggs’ radixmethod. If these logarithms were computed over a period of two years, they representedabout 20 logarithms computed per day, a number which could have been reduced if thecomputations were split between several computers.

2See Glaisher for a simple justification of this proportion [23, pp. 447–448].

5

The logarithms of the cosines were then used to compute the logarithms of the sinesfrom 0◦ to 45◦ using the formula given above

log sin x = log sin 2x+ log sin 30◦ − log sin(90◦ − x)

= log cos(90◦ − 2x)− log cos x− log 2

The logarithms of the tangents were then obtained with

log tan x = log sin x− log cos x

and the logarithms of the cotangents, secants and cosecants were easily derived fromthem.

Moreover, Glaisher observed that Briggs’ and Vlacq’s calculations were independentand that Vlacq did not copy some values from Briggs’ Trigonometria britannica [7].3 Thisfollows from the fact that the values which are common to both tables are those corre-sponding to angles multiples of 3′, and that Vlacq’s Trigonometria artificialis coincideswith the trigonometric values given in Vlacq’s Arithmetica logarithmica for all minutes,as checked by Glaisher [23, p. 444]. In other words, these values have not been copiedfrom Briggs, and the other values are not found in Briggs’ table.

3.4 The 20 first chiliades of the Arithmetica logarithmica

In addition to the trigonometric part, the Trigonometria artificialis contains a copy ofthe first 20 chiliades (1–20000) of the Arithmetica logarithmica, with an errata.4

4 Errors

A number of errors were naturally given by Vega and the erratas to Vega’s tables may beuseful for Vlacq’s tables. A list of errors in Vlacq’s 1633 table appears in Delambre’s His-toire de l’astronomie moderne [13, vol.2, pp. 428–432]. Delambre compared the commonvalues, every 3′. Some errors in the Trigonometria artificialis were also given by Andoyerin 1911 [1]. More recently, an overview of the erratas of Vega’s and Vlacq’s tables wasgiven by Fletcher et al. [16, pp. 919–925].

It is not our purpose to give here a list of all the errors in the original manuscript,but our reconstruction might drive another enthusiast to compile an updated list of allerrors in the Trigonometria artificialis. As an illustration to the real accuracy of Vlacq’stables, we consider the first twelve values of log sin, for which the error can reach up tofour units of the last place:

3Delambre had also analyzed the accuracy of the Trigonometria artificialis [13, vol. 2, p. 423] andconcluded that Vlacq had made use of Rheticus’ table [13, vol. 2, p. 426], and not of Briggs’ table, fromwhich he could have interpolated.

4The copy of Vlacq’s Arithmetica logarithmica from the Complutense University of Madrid is avail-able on google books (id: -XR-2oDEb9oC), but it only contains the Latin introduction, the trigonometricsupplement, as well as the fragment of the logarithms of numbers which was appended to Vlacq’s Trigo-nometria artificialis. This may be the result of a binding error.

5 Vlacq-based tables

Almost all the tables of logarithms published after Vlacq’s Arithmetica logarithmica andTrigonometria artificialis until the 20th century were based on them, with various cor-rections, extensions, or simplifications.

As a most curious example, the 1628 Arithmetica logarithmica and Vlacq’s 1633trigonometric table were even used as a basis for the Chinese tables of logarithms pub-lished around 1720 [48].

Probably the most popular such tables were those of Vega [2, 15], which went intomany editions. Vega’s great Thesaurus logarithmorum completus [51] published in 1794gave the logarithms to 10 places, borrowing them from Vlacq from 1 to 100000, andperhaps from Briggs from 100000 to 101000. The logarithms of trigonometric functionswere taken from Vlacq’s Trigonometria artificialis , only extending them for the firstdegree of the trigonometric functions.

6 Structure of the tables and recomputation

The original Trigonometria artificialis contains an introduction of 52 pages, followed bya first section of tables for the logarithms of the trigonometric functions. This sectionis followed by a second one which is an excerpt of Vlacq’s Arithmetica logarithmica, butonly from 1 to 20000. The last page of that table, for the interval 19951–20000, has beenreset and is followed by an errata. This section is actually a leftover from the Arithmeticalogarithmica, as proven by the signatures of the pages, which have also been reproducedhere. The signatures of the first part were not reproduced.

These two tables are reproduced here. The tables were recomputed using the GNUmpfr multiple-precision floating-point library developed at INRIA [17], and give the exactvalues. The comparison of our table and Vlacq’s will therefore immediately show whereVlacq’s table contains errors, and this is of course one of the purposes of this reconstruc-tion. Apart from the change in accuracy, we have tried to be as faithful as possible to

7

the original tables. Among the slight changes, we mention the uniformization of head-ers. In the original table, there are sometimes variations from one page to the other andthese idiosyncrasies were not included here. A few values have also been changed for apurpose of uniformity. The first logarithms of sines and tangents were 0 in Vlacq’s table,and we have written Infinita instead, like for the logarithm of the first cotangent. Thecorresponding differences which had been left empty by Vlacq were also adapted. In thesecond table, only the first difference was missing and was supplied.

5Note on the titles of the works: Original titles come with many idiosyncrasies and features (line

splitting, size, fonts, etc.) which can often not be reproduced in a list of references. It has thereforeseemed pointless to capitalize works according to conventions which not only have no relation with theoriginal work, but also do not restore the title entirely. In the following list of references, most titlewords (except in German) will therefore be left uncapitalized. The names of the authors have also beenhomogenized and initials expanded, as much as possible.

The reader should keep in mind that this list is not meant as a facsimile of the original works. Theoriginal style information could no doubt have been added as a note, but we have not done it here.
