Aerope's father was Catreus, the son of Minos, and king of Crete. Catreus had two other daughters, Clymene and Apemosyne, and a son Althaemenes. According to the tradition followed by Euripides in his lost play Cretan Women, Catreus found Aerope in bed with a slave and handed her over to Nauplius to be drowned, but Nauplius spared Aerope's life and she married Pleisthenes, who was the king of Mycenae. Sophocles, in his play Ajax, may also refer to Aerope's father Catreus finding her in bed with some man, and handing her over to Nauplius to be drowned, but the possibly corrupt text may instead refer to Aerope's husband Atreus finding her in bed with Thyestes, and having her drowned. However, Apollodorus tells us that Catreus received an oracle saying that he would be killed by one of his children, so Catreus gave Aerope and her sister Clymene to Nauplius to be sold off in foreign lands. But Nauplius kept Clymene for himself and Aerope married Pleisthenes, by whom she became the mother of Agamemnon and Menelaus.
In Mycenae
From Crete, Aerope was taken to Mycenae. And there she became, according to most accounts, the mother of Agamemnon and Menelaus. Their father was either Atreus or Pleisthenes, who was Atreus' son, according to some. For Homer, Agamemnon and Menelaus were the sons of Atreus and Aerope. And although in Euripides' Cretan Women, and the passage by Apollodorus cited above, Aerope was the wife of Pleisthenes, with Apollodorus saying that Pleisthenes was the father of Agamemnon and Menelaus, elsewhere both Euripides and Apollodorus follow Homer. Indeed, most sources do so. However Euripides and Apollodorus were not alone in making Pleisthenes the father of Agamemnon and Menelaus. These included, so we are told, Hesiod, Aeschylus, Porphyry, and "others". Bacchylidescalls Menelaus both "Atreides" and "Pleisthenides"—meaning a descendant of Atreus and Pleisthenes respectively—in the same poem. It is plausible that Aerope could have first married Pleisthenes and then Atreus, with Atreus adopting the children from the first marriage. And indeed some have asserted just this, though this may simply be an attempt to reconcile separate traditions.
Atreus and Thyestes
While the wife of Atreus, Aerope was the lover of Atreus' twin brother Thyestes, and became involved in their power struggle for the kingship of Mycenea, and blood feud. The story was a popular one in Greek tragedy. Aeschylus' play Agamemnon, contains several obscure allusions to the story, which indicate that, by at least 458 BC, the story was well known. There were several other latter plays, all lost, which presumably also dealt with the story. We hear of plays by Sophocles, with titles Atreus, Thyestes, and Thyestes in Sicyon, and by Euripides, with the titles Kressai, and possibly a Thyestes. Agathon, wrote a play titled Aerope, and perhaps so did the younger Carcinus. In addition Euripides' Electra, and Orestes, also contains significant references to the story. Atreus and Thyestes were the sons of Pelops and Hippodamia. Their desire for their father's throne led to the murder of their half-brother Chrysippus, because of which they were banished, and sought refuge in Mycenae. When the Perseid dynasty came to an end, the Myceneans received an oracle saying they should choose a son of Pelops as their king. Aerope and Thyestes, were lovers and Aerope stole the golden lamb from her husband Atreus and gave it to Thyestes, so that the Myceneans would choose Thyestes as their king. According to Hyginus, Aerope was the mother by Thyestes of two sons, Tantalus and Pleisthenes, and in Euripides' Cretan Women, it may have been these children that Atreus famously fed to Thyestes. From Byzantine period annotations to Euripides' Orestes we learn that, in some unspecified Sophocles work, Atreus cast Aerope into the sea in revenge for her adultery and theft of the golden lamb.
The stories told about Aerope, share elements with those told about Auge and Danae. These elements include, foretold killings, sexual impurity by daughters, and their subsequent punishment by their fathers, by being cast into the sea, or given away to be sold overseas. Auge was the daughter of Aleus, king of Tegea, and the mother of the hero Telephus. According to one version of the story, Aleus had received an oracle that his sons would be killed by the son of Auge, so Aleus made Auge a priestess of Athena, requiring her to remain a virgin on pain of death. Nevertheless, she became pregnant by Heracles. Then, by various accounts, she was either cast into the sea, or given to Nauplius to be either drowned or sold overseas, however in all these accounts she ended up in Mysia as the wife of King Teuthras. Danae was the daughter of Acrisius, king of Argos, and the mother of the hero Perseus. An oracle told Acrisius that he would be killed by the son of Danae, so he locked her away. Nevertheless, Danae became pregnant, by Zeus according to most accounts, and was cast into the sea by her father, but survived through the intercession of Zeus.
''Ars Amatoria''
In Ovid's Ars Amatoria, Aerope is given as one of several examples showing that "women's lust", is "keener" than men's and having "more of madness":
