[2][3] The psalter was perhaps produced c. 1310–1320 by one main scribe and, unusually for a work so heavily illuminated, a single artist,[4] who is now known as the "Queen Mary Master".
[6] It remained in the possession of Queen Mary and her successors until 1757, when George II donated the Old Royal Library to the British Museum.
[7] Kathryn Smith argues that specifically the scenes depicting Joseph, if read in the proper historical context, suggest Isabella: "it [the Joseph cycle] functioned in two ways: as a commentary on royal policy and current events during the reign of Edward II, and as an "anti-model" of conjugal fidelity for his queen, Isabella of France.
[8] The psalms are accompanied by over 800 illustrations, which fall into three categories: initials, many containing imagery related to David; large illuminations depicting the Life of Christ; and marginal drawings at the bottom of every page.
According to Anne Rudloff Stanton, "the codex is an intricately designed and encyclopaedic masterpiece, presenting largely visual stories that span the courtly world as well as biblical history."
