Geometria speculativa, by Thomas Bradwardine (ca. 1295-1349), was published in 1511. It was one of the first geometries not based solely on Euclid. The cover of the particular edition examined here contains marginal comments of previous readers.

An edition of Thomas Bradwardine’s Arithmethica was published in 1513. It was a rather brief book of a few pages and considered some basics of arithmetic. The cover illustration depicts fourteen monks listening to a reader depicted in the upper center. One assumes that the lecture concerned mathematics.
