49 Stand 42 Only edition, rare. Edo Hildericus von Varel (1533 - 1599), attended Wittenberg  Univ.  while  Melanchthon  was  still  alive.  He  taught mathematics at Jena from 1564 to 1567, and then held a variety of brief positions teaching oriental languages elsewhere in Germany, before becoming Professor of Theology at Altdorf from 1584 until his death in 1599. Although a career track from mathematics, through languages, to theology would be unusual today, Edo is in many respects a prime example of Melanchthon‘s educational ambitions, which produced humanists with prodigious literary and linguistic skills. Among Edo‘s achievements are several works on astronomy. He was responsible for the first modern Latin translation of Geminus‘s Elements of Astronomy (published in Altdorf in 1590). In addition, he wrote one of a very small number of books on the mathematical techniques of Wittenberg astronomy. According to Edo, the book presents the method Reinhold used in the Prutenic Tables, later adopted by Peucer „and everyone who studied at Wittenberg“.- Nachweis: VD16 H3637, Zinner 2457, not Barchas, not Kenney; KVK: Dresden, Wolfenbüttel, Jena, Halle, Göttingen, Stabi Berlin [verm.

The work seems to be read quite a lot, because we find copies in A. Shaftesbury‘s, in C. Huygens‘ and the Macclesfield library. Honorat de Meynier (ca 1570 - 1638) was an engineer who served with distinction in the Wars of Religion and of the League, retiring in 1608, after „thirty-six years in arms“, to Provence where he produced a number of works of poetry, history, arithmetic, art military and fortification. The present exploration of Euclid was described by Bayle as being „full of good sense.“ - Marie Locoarre.

One plate shows a „Quadrans pour le canonnier“. Mathematician, courtier as well as man of letters and scholar of classical and oriental languages, David Rivault (1571-1616) was an intimate of the great classical scholars Causabon and Scaliger. He was tutor to the young Louis XIII but lost his job when he beat the King‘s dog for continually interrupting their lessons. Rivault was thus entrusted with what was regarded in the France of the ancien regime as one of the most important of responsibilities, the education of royalty. His catholic orthodoxy made his appointment highly acceptable to the papal nuncio. In 1612 he published a design for  the  establishment  of  an  academy  at  the  court. This  academy should teach less theology and more practical arts, mathematics and military exercises and the art of war. He edited Archimedes in 1615.- KVK: Wolfenbüttel, Düsseldorf, Stabi München; COPAC: only BL London [also 1608]; OCLC: New York Public; Harvard; Cockle 676; Spaulding & Karpinski 81; Riling 67.
