' Ouvrage ou Tauteur decouvre sa faiblesse pour I'astrologie.'— B/ogf. Gen. It is recorded that he was extremely 

 successful in his astrological predictions, which should make this work of great value to British neo-astrologers in the 

 Twentieth Century.

' In this rare work Magini speaks of the rarity of concave mirrors in his time, and mentions several made by himself. . . . 

 The mirrors made by him were of a quite extraordinary size, measuring 5 feet in their circumference. They were 

 employed for various uses aud (specially to ascertain the different heat of the sun during the various seasons. Magini 

 speaks also of the camera obscura as having been described before Porta by Ausonio, in his theory of the Concave 

 Mirror, published by Magini himself.'— Li6/'i Catalogue.

a copious account of Magini's Ephem rhhs will be found in Delambre's Ilistoire de I'astronomie du moyen age. Kepler, 

 wlio relerred to Magini as 'sunimus in professions inathematica vir', invited him to help in the compilation of new 

 astronomical tables (afterwards known as the Rudolphlne Tables). According to Biogr. Gen., this was done by 

 Copernicus— a palpable error, as Copernicus died 12 years before Magini's birth.

'Ses ecrits preuvent qu'il a fait une etude approfondie des travaux de Copernic ... On recontre dans ses ouvrages des 

 transformations et des theoremes que d'habiles astronomes avaient cru de nos jours decouvrir pour la premiere fois.' — 

 G. Lilrri. 



According to the same authority, the above and the .Yoroe co-lestium orbium theoricce, published in 1G08, were the only 

 two works in which the author follows wholly the Copernican system. In all the works published between 1.J85 and 1608 

 he adopted a curiously involved system of his own, probably inspired by a fear of the Inquisition, with which not many 

 years afterwards Galileo got into difficulties.
