Sphaera mundi was originally composed in the 13th century by Joannes de Sacro Bosco, a 13th century mathematician and astronomer, also known as John Holywood. The work deals with the shape and apparent movement of the earth and other heavenly bodies and was the single most influential astronomy text for centuries.
