Book IX, 485: From his Aethiopica, iii. 2

I sina Thetis, golden-haired Thetis, the immortal daughter of the sea-god Nereus, who by the counsel of Zeus wedded Peleus, the glory of the sea, our Aphrodite, her who bore from her womb the raging spearman, the Ares of war, the lightning of Greece, divine Achilles, whose glory reaches to heaven. By him Pyrrha bore Neoptolemus, the sacker of Troy and saviour of Greece. Be gracious unto us, blessed hero Neoptolemus, now lying in Delphian earth ; receive favourably this sacrifice and ward off all fear from our city. Thetis I sing, golden-haired Thetis.
