This 13th century Flemish Psalter, another survivor of Edwardian purges, was presented to Queen Mary Tudor by a London grocer Ralph Prynne.

Edward IV owned this indistinctive collection of medical and instructional texts before his accession to the throne. A note on one of the front flyleaves refers to him as the Count of March ('Iste liber co[n]stat Edwardo comiti / marchie p[rim]ogenit[us] fili[us] ducis / Eboraci'). The manuscript also bears the Westminster inventory number 'no. 806' (f. 3) confirming its continuous royal ownership.
