Hidden in Plain Sight: Musical Treasures in the Penn Library Curated by Marjorie Hassen Otto E. Albrecht Music Library University of Pennsylvania

Anthologion Anthologion Manuscript, 17th century Ms. Codex 140 Anthologia were service books containing Byzantine liturgical texts, often with neumatic notation, compiled either for private use or monastic communities. They typically contained the verses for the 8 octoechos (tones or modes) and stikhera from the great feasts of the liturgical year. This volume, likely compiled in the 17th century (the earliest such volumes date from ca. 1300), includes theoretical treatises on music and psalms for the office, all with musical notation. The opening exhibited here displays a diagrammatic depiction of the relationship between the tones of the octoechos.
