De Bissexto Liber (1637)

De Bissexto Liber est opus Erycii Puteani, scriptum anno Domini MDCXXXVII. In hoc libro, auctor tractat de anno bissextili, quod est annus, qui habet diem intercalarem, qui additur ad mensem Februarium, ut annus consistat ex trecentis sexaginta sex diebus. Puteanus explicat rationem, cur bissextus annus necessarius sit, et quomodo computatio temporis facta est in antiquis temporibus. Liber est utilissimus ad intelligendum calendarios et tempora, et est scriptus in lingua Latina eleganti et clara.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
