This manuscript, illustrated with 155 marginal paintings, is one the few surviving “marginal psalters,” in which images provide a pictorial commentary on the Biblical text. Other examples include the Khludov Psalter (circa 850, Moscow, State Historical Museum, Muz. 129), the Barberini Psalter (circa 1050, Vatican City, Biblioteca Apostolica Vaticana, Vat. Barb. Gr. 372), the Theodore Psalter (1066, London, British Library, Add. Ms. 19,352), and a Cyrillic psalter made in Kiev (1397, Saint Petersburg, National Library of Russia, cod. OLDP, F6). The marginal psalter of the Walters Museum was apparently copied from the same 11th-century model as the Saint Petersburg manuscript, as the iconography of the two is very similar.
