In Plato's "Symposium," written c. 385 BC, the speaker Phaedrus holds up Achilles and Patroclus as an example of divinely approved lovers. Phaedrus argues that Aeschylus erred in claiming Achilles was the "erastes" because Achilles was more beautiful and youthful than Patroclus (characteristics of the "eromenos") as well as more noble and skilled in battle (characteristics of the "erastes"). Instead, Phaedrus suggests that Achilles is the "eromenos" whose reverence of his "erastes", Patroclus, was so great that he would be willing to die to avenge him.
