Myth about Triangulum

The Greeks used to know this gathering of stars as Deltoton, which was after its shape as it resembled the delta which is a Greek letter.  According to the Eratosthenes this constellation represented River Nile Delta.  Then according to the Hyginus, this constellation was said to be the Sicily Island. Sicilia was among the early names that were given to the constellation. The reason was that Ceres (the patron goddess of Sicily Island) said that they begged to have a bigger planet (Jupiter) so that the island can be situated in the sky.
