[200] Gregoire de St. Vincent (1584-1667) published his _Opus geometricum
quadraturae circuli et sectionum coni_ at Antwerp in 1647.

[201] This appears in _J. Scaligeri cyclometrica elementa duo_, Lugduni
Batav., 1594.

[202] Adriaen van Roomen (1561-1615) gave the value of [pi] to sixteen
decimal places in his _Ideae mathematicae pars prima_ (1593), and wrote his
_In Archimedis circuli dimensionem expositio & analysis_ in 1597.

[203] Kaestner. See note 30 on page 43.

[204] Bentley (1662-1742) might have done it, for as the head of Trinity
College, Cambridge, and a follower of Newton, he knew some mathematics.
Erasmus (1466-1536) lived a little too early to attempt it, although his
brilliant satire might have been used to good advantage against those who
did try.

[205] "In grammar, to give the winds to the ships and to give the ships to
the winds mean the same thing. But in geometry it is one thing to assume
the circle BCD not greater than thirty-six segments BCDF, and another (to
assume) the thirty-six segments BCDF not greater than the circle. The one
assumption is true, the other false."

[206] The Greek scholar (1559-1614) who edited a Greek and Latin edition of
Aristotle in 1590.

[207] Jacques Auguste de Thou (1553-1617), the historian and statesman.

[208] "To value Scaliger higher even when wrong, than the multitude when
right."

[209] "I would rather err with Scaliger than be right with Clavius."

[210] "The perimeter of the dodecagon to be inscribed in a circle is
greater than the perimeter of the circle. And the more sides a polygon to
be inscribed in a circle successively has, so much the greater will the
perimeter of the polygon be than the perimeter of the circle."

[211] De Morgan took, perhaps, the more delight in speaking thus of Sir
William Hamilton (1788-1856) because of a spirited controversy that they
had in 1847 over the theory of logic. Possibly, too, Sir William's low
opinion of mathematics had its influence.

[212] Edwards (1699-1757) wrote _The canons of criticism_ (1747) in which
he gave a scathing burlesque on Warburton's Shakespeare. It went through
six editions.

[213] Antoine Teissier (born in 1632) published his _Eloges des hommes
savants, tires de l'histoire de M. de Thou_ in 1683.

[214] "He boasted without reason of having found the quadrature of the
circle. The glory of this admirable discovery was reserved for Joseph
Scaliger, as Scevole d
