De Vera Anni Forma: Sive De Recta Eius Emendatione est liber a Josepho Zarlini scriptus, anno 1580 editus. In hoc libro, Zarlini de vera forma anni disputat et rectam eius emendationem proponit. Liber constat ex quinque capitibus, in quibus auctor de annis solis, lunae, planetarum, et anni tropici tractat. Zarlini argumentat quod annus tropicus, qui est tempus inter duos solstitia, est verus et rectus annus, et quod annus sideralis, qui est tempus inter duos transitus solis per eundem punctum aequinoctialis, non est verus annus. Liber est valde importantis in astronomia et in tempore suae publicationis fuit laudatus pro sua eruditione et perspicuitate.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.
