In Plato's Symposium, Penae (or Penia) was the personification of poverty an need. She married Porus at Aphrodite's birthday and was sometimes considered the mother of Eros. Her sisters are Amechania and Ptocheia. Penia was also mentioned by other ancient Greek writers such as Alcaeus (Fragment 364), Theognis (Fragment 1; 267, 351, 649), Aristophanes (Plutus, 414ff), Herodotus, Plutarch (Life of Themistocles), and Philostratus (Life of Appollonius).
