' 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 aad especially 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.' Libri Catalogue.

A copious account of Magini's Ephem ritlts will be found in Delambre's Hixtoire de I'aslronomie du mnyen n<je. Kepler, 

 who referred to Magini as 'sununus in professione mathematioa vir', invited him to help in the compilation of new 

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

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

According to the same authority, the above and the Xovce cu'lestium orbium theories, published in 1C08, were the only 

 two works in which the author follows wholly the Copernican system. In all the works published between 1585 and 1GOS 

 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.
