The most important manuscript in the Pantokratoros Monastery is the 9th century parchment psalter with the number 61. It is one of the three surviving psalters which was made immediately after the end of the iconoclastic period and had the unique characteristic of being decorated in the margins of the text with small images. The subjects of these miniature images, which are painted in a relatively free style, are drawn from the psalms as an expression of active defiance to the constraints of the iconoclasts. The parchment sheet of codice 61 had been previously used in another book with capital letters, which was subsequently erased in order to write the psalter; parchment is an expensive material. This palimpsest manuscript, with its long history, is a priceless, living witness to the iconoclastic conflict.
