Garlandus Compotista
Garlandus Compotista, also known as Garland the Computist, was an early medieval logician, astronomer, and mathematician of the eleventh-century school of Liège. Little is known of his life; the Dialectica published under his name by L. M. de Rijk is now commonly attributed to Gerlandus of Besançon. Gerlandus was most known for his Computus Gerlandi a computus that was more complex and accurate than those used in the Early [Middle Ages]. Using more exact mathematical and astronomical methods Garlandus changed the estimates for the Date of birth of Jesus.
