Work dossier · summary and historical context
A collection of minor astrological texts attributed to the 11th–12th-century Georgian Neoplatonist Ioane Petritsi. The register is technical, blending astronomical observation with philosophical commentary. The texts survive in a single manuscript tradition with lacunae and marginal corrections, based on a 19th-century copy of a lost medieval exemplar. They were used in Georgian monastic schools as part of the quadrivium but never entered the liturgical canon. The edition does not collate variant readings, and technical terms are often ambiguous. The content may be influenced by Arabic and Byzantine sources, but parallels are not identified in the edition.
This work provides rare evidence of the transmission of astrological and computistical knowledge in medieval Georgian monastic education, blending Neoplatonic philosophy with practical prediction. It illustrates the cross-cultural exchange between Byzantine, Arabic, and Georgian scholarly traditions, and its attribution to Petritsi links it to the broader intellectual movement of Georgian Neoplatonism.
The texts are traditionally attributed to Ioane Petritsi, a Georgian Neoplatonist active in the 11th–12th centuries, associated with the Gelati and Athonite monastic centers. The work likely dates to the 12th century, but no colophon or external witness confirms authorship or precise date. The texts survive in a single manuscript tradition, with lacunae and marginal corrections; the TITUS edition is based on a 19th-century copy of a lost medieval exemplar. These astrological writings were used in Georgian monastic schools as part of the quadrivium, reflecting the integration of Byzantine and Arabic scientific learning into Georgian scholarly circles. The genre includes brontologia and lunar prognostications, predicting weather, crops, and events based on epact numbers. The text is preserved in Ms. A-290, fol. 258r-261r, a Georgian manuscript from the Athonite or Gelati tradition.
