The movement in the two left-hand slabs on the north is largely to the left. Although the first group of centaur and hoplite, BM 521:1 and 2, is virtually identical to the pair BM 522:1 and 2, the hoplite on BM 521 props himself on his shield, which serves as a visual stop to the centaur's charge and as a reinforcement to the axis of the north side. The two figures on the left of the same slab, BM 521:3 and 4, repeat the pair of woman and centaur of BM 522:1 and 2. Here, however, the woman is not attacked by the centaur but runs past him. The centaur directs his attention to the hero on the next slab, BM 520:2, at whom he hurls a rock. The hero already grapples with one centaur, BM 520:1. As the only hero to engage two centaurs at once, and because of his proximity to the woman being carried away, BM 520:3, he must be Peirithoos. The woman is Hippodameia, the only woman being abducted.
