ALOIDAE (aro-i'de), or ALOADAE; i.e., Otus and Ephialtes, in ancient Greek legend, the twin sons of Aloeus or Poseidon, celebrated for their extraordinary stature and strength. According to Homer (Od., xi. 3o5), they made war upon the Olympian gods and endeavoured to pile Pelion upon Ossa in order to storm heaven itself, but Apollo destroyed them before they reached manhood. In the Iliad (v. 365) Ares is imprisoned by them, but delivered by Hermes. They sought Artemis and Hera in marriage, whereupon Artemis appeared between them in the shape of a stag, which they endeavoured to kill, but slew each other. The Aloidae (Gr. a/de=threshing-floor) represent the spirits of the fertile earth and agriculture.
