Psalterium. Latin, French. 13th century. Parchment. Ilum. 15,5 x 10,5 cm. K. 170 + VI. 19th century velvet binding. Rps BN I 8003 Psałterz wilanowski, called also Psałterz Potockich is a 13th century hand-written psalter. Thanks to its excellent painting technique, perfect drawings and conscientious execution of full-page miniatures, is regarded as one of the best works of Paris studios in the early Gothic period. It is ornamented with 4 fullpage miniatures, six figurative initials (which, in keeping with the principle adopted for this kind of psalter, mark the beginning of psalms), small calligraphic initials and colourful interlines. The Psalter, probably purchased in Paris at the beginning of the 19th century for Stanisław Kostka Potocki’s Wilanów Library, was transferred in 1932 to the National Library together with the Wilanów collections. In 1939 it was evacuated to Canada, whence it returned twenty years later.
