Eos, the goddess of the dawn, embarked on several ill-fated trysts with mortal men, including Tithonos and Kephalos. Deeply besotted with the former, a Trojan prince, Eos begged Zeus to grant him immortality so that they might never be parted; Zeus consented, but Eos had forgotten to ask for eternal youth, and so her young lover withered away into interminable old age. Kephalos, a handsome youth whom she kidnapped whilst he was hunting, was reluctant to become Eos' lover, and the rejected goddess was forced to return him to his wife Procris after he pined incessantly for her; it is likely that the latter is depicted here (cf. C. Weiss, 'Eos', Lexicon Iconographicum Mythologiae Classicae, vol. III, 1984, Zurich and Munich, nos 47, 61, 76 and 80).
