Texts
Latin commentary on Virgil’s Eclogues (al. Bucolics) and Georgics. It is regarded as a representative of the so-called Servius auctus or Servius Danielis (DS), an expansion and reworking of Servius’ commentaries along with other material incorporated into the text. The extant manuscript versions, different though each of them may be, represent an early medieval recension of material which probably originated in late antiquity and which may have been written by the commentator Philagyrius.

A 9–12.771. Scholia written in the outer column. This text lacks the scholia which in Bern MS 172 are found in the right margin, suggesting that the scholia were only incompletely copied. It has been argued that the text derives directly from Bern MS 172.

abstract:
The 'Digital Library of Late-Antique Latin Texts' was officially established on March 1, 2010, thanks to funds granted by the 'Regione Piemonte' to support research in the area of Humanities and Social Sciences. The project, conceived by Raffaella Tabacco, was developed and substantiated by her and Maurizio Lana. It aims to produce a digital corpus of late-antique Latin literary texts (from the second to the fifth century AD), making it freely available to the scholarly community.
