Resumen de Un nuovo titolo iniziale nella collezione ercolanese e un nuovo libro (del trattato) sul Sole di Demetrio Lacone (P.Herc. 177)
Differently than what has formerly been suggested, P.herc. 177 preserves the initial, not the final, title of a roll. Besides, the author of the work it transmits is not Philodemus, but Demetrius Laco. Finally, its subject is not geometrical, but astronomical. P.herc. 177 probably belongs to the same treatise as P.herc. 1013, which was devoted to the Epicurean discussion concerning the Sun and of which these papyri might represent two different books.
