GRYNAEUS (Simon), son to a peasant of Suabia, born in 1493, was Greek professor at Heidelberg, in 1523. He took a tour into England, and received great civility from the lord chancellor Sir Thomas More, to whom Erasmus had recommended him. He was a learned and laborious man, and did great service to the commonwealth of letters. He was the first who published the Almagest of Ptolemy in Greek. He also published a Greek Euclid, and Plato's works, with some commentaries of Proclus.
