The question to be discussed in this paper can be put in simple terms: at what date were the collections of scholia on classical Greek authors compiled? Scholars have given two conflicting answers. The first was put forward by J. W. White in his edition of the scholia to Aristophanes' Birds. Developing an opinion of Dindorf, he suggested that the archetype of the scholia was a large parchment codex of the fourth or fifth century, which contained in the margins a (...) commentary drawn from several sources. A very similar view has been expressed about the scholia to Apollonius Rhodius and Pindar. (shrink)
