Through the study of some specific passages, this paper tries to show how Ovidian critics have taken advantage of Catullus’s text either to defend readings from the recentiores or to produce conjectures on Ovid’s text. The following passages are addressed: Ou. met. 14,531; epist. 6,154 (and 12,180); met. 6,656-658; 10,536; 1,689 (and 2,761) in correspondence to Catull. 64,10; 64,21; 65,14; 64,252; 63,71 respectively. Furthermore, it is also suggested that scholars working on different authors should collaborate more closely.
