An eighth-century Latin version of a Greek edition of Aratus preserves valuable ancient scholarship on the Phaenomena, including material not preserved in Greek. Examination of over thirteen thousand Latin–Greek correspondences enables one to interpret passages of the Latin that have so far resisted analysis, including information about an ancient edition equipped with critical signs and commentary, ancient discussion of the primary narratee in Aratus and Homer, and the alternative proem to Anclides (SH 84).
