This new critical edition of Aulus Gellius’ Noctes Atticae is intended to replace the previous Oxford Classical Text by Peter K. Marshall, published in 1968 but soon superseded by Marshall’s own later discoveries as well as by other scholarship. Based on a thorough reconsideration of the manuscripts, of the indirect tradition, and of both the Latin and the Greek text, it evinces a more sceptical, less trusting approach than that of many recent editors and provides numerous emendations and suggestions, while correcting the attribution of previous scholars’ conjectures in several places.
