Abstract

Cicero's Topica is transmitted as part of the so-called Leiden corpus; but it appeared in only two of the three Carolingian manuscripts carrying that corpus, and in both it lacked 1–3, 28 tratuum–73 Haec. During the ninth century, however, B was supplemented by the addition of folios which completed the text. In 1860 these folios were officiously transferred to A. There are a large number of integri, dating from the tenth century on. Editors have picked more or less at random from this pile to back up the evidence of β. They are also blessed with a detailed and intelligent commentary on the Topica written by Boethius. ‘That the text of the commentary influenced manuscripts of Cicero has been suspected but not proved’.
