"small tables" (Gouda, i
SAMH, Librije-coll. 508 L.
D 28)
Yet that does not trouble me, for I know that I have done a work most
welcome to many learned mathematicians, and that those books will in a few
years be held in great esteem, and that I shall receive some thanks from
posterity, just as some erudite men have already made honorable mention of me
in their books".
This reveals a little more about Vlacq's character, but the prediction about
his tables proved to be right!
In the Hague, Vlacq has published between 1651 and 1667 a number of
reprints of the tables from Arithmetica Logarithmica, Part II, but in a completely
different form: the
tables had been
reduced to a j
precision of 7
decimals and to the
number range 1 to
10,000. The book
containing these
"small" tables, was
now octavo-bound
in a very portable
format (some 11 by
17 cm, or even
slightly smaller).
This was the start of
the long and
successful series of
the "Vlacq table"
publications over
the next 150 years.
