Acker, Paul. "The Emergence of an Arithmetical Mentality in Middle English Literature." 28 (1994): 293-302.
Arithmetical methods passed from Pythagoras to Boethius, who passed these ideas on to Cassiodorus and Isidore. Bartholomaeus Anglicus picks up these ideas in De proprietatibus rerum, translated by Trevisa into Middle English. In the twelfth century, algorism began to replace arithmetic. Gower refers to this new arithmetic in the Confessio amantis in a stanza borrowed from Brunetto Latini. The Court of Sapience also reveals a shift in mathematical models. The Art of Nombryng and Mum and the Sothsegger give evidence that even those writers not concerned with mathematics were becoming aware of it.
