Judging from the number of manuscript copies that survive today, for the next 400 years it became the most widely read book on that subject.\u003cbr\u003e He also wrote a short textbook which was widely read and influential in Europe during the later medieval centuries as an introduction to astronomy. In his longest book, on the computation of the date of Easter, Sacrobosco correctly described the defects of the then-used Julian calendar, and recommended a solution similar to the modern Gregorian calendar three centuries before its implementation.\u003cbr\u003e\u003cbr\u003eVery little is known about the education and biography of Sacrobosco. For one thing, his year of death has been guessed at 1236, 1244, and 1256, each of which is plausible and each lacking adequate evidence.\u003cbr\u003e=================================================\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003eThank You \r\n\u003c\/h4\u003e\n\u003cp\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003c\/p\u003e\r\n\u003cp\u003eRefund Policy: We will issue a FULL REFUND, 100% money back if you are not satisfied with your purchase.
