COM3IANDINE, FREDERIC, both in 1509, at Urbino, of a good family, was at first in the service of Clement VII., after whose death he studied medicine at Padua. Unsatisfied with the state of this science, he applied himself to mathematics, and finally settled at Verona as the instructor of the Duke of Urbino and his son. He died there in September 1575.
This is all that is generally stated as known of Commandinc, except the evidence which his writings afford that he is to be placed at the head of all the commentators on the mathematics of the Greeks, whether as respects the care which he took to select and print valuable remains (several of which would probably have been lost but for him), or the knowledge which be displayed in the treatment of difficult and corrupt texts. The list of works which we have collected is as follows. The dates stand at the beginning, and separate the titles :— 1:48. Venice: the Peammitea and Statical Treatise of Archimedes, in Latin, with notes (from a bad text). 1558, Venice: Ptolenly's Plardaphere, with commentary, in Latin; in the same book is Jordanus, also with a commentary. 1562, Rome: the Analemma of Ptolemy, with commentary.

With this came his own work on Horology, printed at Venice. 1565, Bologna; and Pesaro, 1572: Archimedes on Floating Bodies, with commentary, Latin. 1566,

A translation into English, with Commanding's preface, Is appended to the second edition of Dee's Euclid, 1660. 1572, Pesaro: Euclid in Latin, fifteen books with scholia, in folio.
