Clavius, Chuistopher

, a German Jesuit, was born at Bamberg, in Germany, in 1537. He became a very studious mathematician, and elaborate writer, his works making five large folio volumes; and containing a complete body or course of the mathematics. They are mostly elementary, and commentaries on Euclid and others; having very little of invention of his own. His talents and writings have been variously spoken of, and it must be acknowledged that he exhibits more of industry than genius. He was sent for to Rome, to assist, with other learned men, in the reformation of the calendar, by pope Gregory; which he afterwards undertook a defence of, against Scaliger, Vieta, and others, who attacked it. He died at Rome, the 6th of February, 1612, after more than fifty years close application to the mathematical sciences. 2
