He wrote an essay on the Hindu-Arabic numeral system which became the most widely read introduction to that subject in the later medieval centuries. He also wrote a short astronomy textbook, De sphaera mundi, which was widely influential as an introduction to astronomy. In De Anni Ratione, his longest and most original book, Sacrobosco correctly described the defects of the then-used Julian calendar, and, three centuries before its implementation, recommended a solution much like the modern Gregorian calendar.Credit:Science Source / Science SourceSize:3330px × 4050px (~38 MB)Get PricingHow Will The Visual Be Used?ShareKeywords:13th century-astronomer-bw-catholic-DE SPHAERA MUNDI-famous-history-johannes de sacrobosco-man-medieval-monk-personality-scholarModel release:N/AParent folder:2018-07-15 LOC89
