Delmedigo, Joseph Solomon, 1591-1655.
Sefer Elim [The Book of Elim (a Biblical place name)]
Amsterdam: Manasseh ben Israel, 1628.

A discussion of problems in mathematics, natural philosophy and metaphysics.

Delmedigo, a doctor’s son, was admitted at age 15 to the University of Padua, then in the Republic of Venice. As a medical student he studied under Galileo (1564-1642) geometry and geocentric astronomy. Astronomy and astrology were legitimate diagnostic tools at the time. In 1620 he settled in Vilna and became the private physician of Albert III Radziville (1589-1636), its Polish ruler. Elim discusses problems in mathematics, natural philosophy and metaphysics. It also includes the first explanation of the theories of Copernicus (1473-1543) in Hebrew. The book was edited and published by another Renaissance Jew, the famous Manasseh ben Israel (1604-1657). Manasseh, son of a Portuguese Converso who returned to Judaism, became a highly respected Talmudic scholar, and established in 1626 the first Hebrew printing press in Amsterdam.
