The Linear B tablets of the Mycenaean Greeks preserve no mythic narratives, so Homer is our earliest source. Mycenaean artifacts indicate the importance of unnamed goddesses and goddess votive (?) figurines continue in use. In art the bull is an important symbol, as is the labrys, the Minoan sacred ax. Linear B records refer to "the (two) ladies and the king," and "the (two) ladies and Poseidon." Is this the sort of triadic grouping that sometimes occurs in association with the Twin Goddesses? Alongside this Pelasgian substratum, Linear B records the names of Indo-European gods. Clearly, a great deal of syncretism was occuring.

There is a myth in Greek that deals with a Minoan goddess (or possibly two goddesses!). The text itself of course does not antedate Homer, but its central figure does. The myth is of Britomartis, and a Greek text in which it is preserved specifies that her name is Cretan for "The Sweet Virgin." Little is known of the Cretan language, but the name is not Greek and appears to be Cretan. Further, in post-Minoan (Mycenaean and later) times there was a temple to Britomartis at Kalydonia in western Crete. Britomartis is said to bear the epithet Diktynna because she caught the eye of King Minos. He pursued her, and she ran from him on foot for nine months. Realizing that she was about to be caught, she chose death over the loss of her virginity. She threw herself off a cliff, simultaneously escaping Minos and surviving by virtue of falling into some fishers' nets -- diktna in Greek.
The nine-month footrace certainly seems to put us into the realm of fertility, but we cannot know precisely what it meant. The Greek explanation that Britomartis is called Diktynna because she fell into diktna is known as a folk etymology -- a traditional etiology for a word or name whose true source or meaning is no longer known. In actuality Diktynna is another Minoan figure, the goddess of Mt. Dikte. It is possible that Diktynna and Britomartis together were a realization of the Twin Goddesses. On the other hand, since Britomartis seems to be associated with western Crete and Mt. Dikte is on the eastern half of the island, perhaps they are two localized names for essentially the same goddess -- or perhaps the two originally were completely independent of one another.

The Greek sources variously claim that Britomartis is a nymph in the retinue of Artemis or that Britomartis is simply another name for Artemis. If, as seems likely, Britomartis was a virgin goddess, it is logical that she become associated with the Greek virgin goddess, Artemis.

Finally, one Greek source specifies her parents as Zeus and Karme; since nothing is known of this woman, the reference is not illuminating.
