Marco Fressura disseminates the first results of his inquiries in the Vienese Papyrussammlung; a particular attention is devoted to P.Vindob. inv. L 00158, which appears to preserve a fragment from Hermeneumata Monacensia on one side, and on the other a Vergilian glossary. Fressura dwells upon the conservation of the papyrus (it was re-used into binding a later codex) and tries to put it in context: it probably was destined for Greek-speaking readers to learn Latin. L 151, as many other Latin or bilingual fragments, might come from a library fallen into disuse, and whose items were scattered.
