Athenian lekythos. Eos, the winged goddess of dawn who accompanies her brother Helios across the sky each morning, is probably depicted on this fifth-century B.C. oil jar. In this scene, she is very likely pursuing her lover Tithonus (pictured on the reverse side of the 15-inch-tall flask). In Greek myth, Eos requests that Zeus grant Tithonus immortality, but she forgets to ask also for immortal youth—so Tithonus grows forever older and more decrepit.
