Hecaterus
In Greek mythology, Hecaterus or Hekateros was a minor god and the father of five daughters (the Hecaterides) by the daughter of Phoroneus, and through them grandfather of the Oreads, Satyrs, and Curetes.
His name has been interpreted as referring to the hekateris (a rustic dance which involves quickly moving hands), and himself as a patron or personification of this dance. On the other hand, it has been suggested that the name "Hekateros" (which stands in the genitive case Ἑκατέρου in the original Greek text) could result from corruption of the purported ἑκ Δώρου "of Dorus".
