Gemme Frisii, Medici Et Mathematici, De Radio Astronomico Et Geometrico Liber est liber a Rainero Gemma Frisio scriptus anno MDLVIII. In hoc libro, Gemma Frisius, qui erat medicus et mathematicus, tractat de radio astronomico et geometrico, quae sunt instrumenta ad mensurandum altitudinem stellarum et locum eorum in caelo. Liber est divisa in tres partes: prima pars est de radio astronomico, secunda pars est de radio geometrico, et tertia pars est de usu utriusque radii in astronomia. In his partibus, Gemma Frisius explicat constructionem et usum radii, et ostendit quomodo adhiberi possunt ad mensurandum altitudinem stellarum et locum eorum in caelo. Liber est consideratus ut unum ex libris clavibus in historia astronomiae et instrumentorum mathematicorum.This Book Is In Latin.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
