Psalms with scholia (incomplete). | Psalms with scholia written in majuscule script, with a few notes in minuscule script added by a later hand. Each stichos begins with an initial, rubricated and adorned with gold. The codex is nowadays incomplete: the beginning up to Ps 20:9b is missing, as is the final portion from Ps 148:7a onwards. The section now located in St Petersburg was originally situated between folios 72 & 73. Within the main body of the manuscript, ten leaves are missing between folios 161 & 162, resulting in the loss of Ps 118:100a–123:6a, and two leaves are missing between folios 168 & 169, leading to the loss of Ps 134:16a–135:11b. The initial of each psalm is enlarged, and the initial of each verse is highlighted in red and yellow. The titles of the psalms are rubricated. The scholia predominantly convey hexaplaric readings (these readings were fully collected by F. Albrecht in 2023). The manuscript has been heavily trimmed, with some scholia partially cut off. | Text-type: L.
