Computus
In addition to the trivium, four other liberal arts constituted the mathematical
branch of advanced studies, known as the "quadrivium": arithmetic,
geometry, astronomy, and music. This manuscript, which features an astronomical
diagram of the planets encircling the earth, is a computus, or
text designed to facilitate calendrical calculations. The geocentric diagram
is included to provide theoretical context for the practical exercises.
Purchased in 1888 for A.D. White.
Computus. Germany, ca. 1438.
