SCHONER (John)

, a noted German philosopher and mathematician, was born at Carolostadt in the year 1477, and died in 1547, at 70 years of age.—His early propensity to those sciences may be deemed a just prognostication of the great progress | which he afterwards made in them. So that from his uncommon acquirements, he was chosen mathematical professor at Nuremburg when he was but a young man. He wrote a great many works, and was particularly famous for his astronomical tables, which he published after the manner of those of Regiomontanus, and to which he gave the title of Resolutæ, on account of their clearness. But notwithstanding his great knowledge, he was, after the fashion of the times, much addicted to judicial astrology, which he took great pains to improve. The list of his writings is chiefly as follows:

1. Three Books of Judicial Astrology.

2. The Astronomical Tables named Resolutæ.

3. De Usu Globi Stellif<*>ri; De Compositione Globi Cœlestis; De Usu Globi Terrestris, et de Compositione ejusdem.

4. Æquatorium Astronomicum.

5. Libellus de Distantiis Locorum per Instrumentum et Numeros Investigandis.

6. De Compositione Torqueti.

7. In Constructionem et Usum Rectanguli sive Radii Astronomici Annotationes.

8. Horarii Cylindri Canones.

9. Planisphærium, seu Meteoriscopium.

10. Organum Uranicum.

11. Instrumentum Impedimentorum Lunæ.

All printed at Nuremburg, in folio, 1551.

Of these, the large treatise of dialling rendered him more known in the learned world than all his other works besides; in which he discovers a surprising genius and fund of learning of that kind.
