Commandine, Frederick

, a celebrated mathematician and linguist, who was born at Urbino in Italy, in 1509, and died in 1575, was famous for his learning and knowledge in- the sciences. To a great depth and just taste in the mathematics, he joined a critical skill in the Greek language; a happy conjunction which made him very well qualified for translating and expounding the writings of the Greek mathematicians. And, accordingly, with a most laudable zeal and industry, he translated and published several of their works for the first time. On which account, Francis Moria, duke of Urbino, who was very conversant in those sciences, proved a very affectionate patron to him. He is greatly applauded by Bianchini, and other writers and he justly deserved their encomiums. Of his own works Commandine published the following: 1. “Commentarius in Planisphserium Ptolomosi,” 1558, 4to. 2. “De Centre Gravitatis Solidorum,” Bonon. 1565, | 4to. 3. “Horologiorum Descriptio,” Rom. 1562, 4to. He translated and illustrated with notes the following works, most of them beautifully printed, in 4to, by the celebrated printer Aldus: 1. “Archimedis Circuli Dimensio de Lineis Spiralibus Quadratura Parabolae de Conoidibus et Sphseroidibus de Arenas Numero,” 1558. 2. “Ptolomaei Planisphaerium et Planisphaerium Jordani,” 1558. 3. “Ptolomuei Analemma,” 1562. 4. “Archimedis de iis qua? vehuntur in aqua,” 1565. 5. “Apollonii Perggei Conicorum libri quatuor, una cum Pappi Alexandrini Lemmatibns, et Commentariis Eutocii AscalonitaV‘ &c. 1566. 6.” Machometes Bagdadinus de Superficierum Divisionibus,“1570. 7.” Elementa Euclidis,“1572. 8.” Aristarchus de magnitudinibus et distantiis Solis et Luna:,“1572. 9.” Heronis Alexandrini Spiritualium liber,“1583. 10.” Pappi Alexandrini Collectiones Mathematics.’," 1588. ¹
