The Greeks called the "Triangle" also "Trigonon", "Delta", or "Deltoton". Among others they saw the Nile Delta in it. But the Triangle also stands for Sizily, an island in the Mediterenean Sea, which is consecrated to Demeter. It’s said that Persephone was kidnapped from there into the Hades, the underworld. Hades, also the name of the god of the underworld, fell in love with Kore. He asked his brother Zeus, the godfather, to marry her. Zeus neither agreed nor declined the request, because he knew that Kore wouldn’t want to move into the dark underworld. So Hades kidnapped Kore and brought her to the underworld against her will, where she was named Persephone from there on.
