Ars Amatoria
The centaur lovers' episodic digression and their "ideally mutual relationship", within Nestor's narration of the Battle of the Lapiths and Centaurs in Met. 12. Ovid, alludes to two didactic poems, Lucretius' De Rerum Natura and Ovid's own Ars Amatoria III. In the Cyllarus-Hylonome interlude he explores hybridity itself illustrating the relationships and "possible combinations of a number of conceptual opposites: natura and cultus, human and animal, male and female, love and war, and the contrasting values of lyric-elegiac and epic poetry".
