Family
Son of Cronus and Rhea; brother of Zeus, Hades, Hera, Demeter, and Hestia in the standard Olympian genealogy.
Realm
Sea, earthquakes, horses, and aspects of coastal and civic power. Ancient religious roles were broader than modern character summaries.
Symbols
Trident, horse, bull, dolphin, chariot, waves, and coastal springs. Their importance changes by artwork and story.
Temperament
Majestic, competitive, protective, and dangerous when dishonoured. Myths resist reducing him to a single moral type.
Limits
He is immensely powerful but not omnipotent. Fate, Zeus’s senior authority, other gods, bargains, and narrative circumstance can constrain him.
Reading ancient mythology
Greek myth survives through works created in different regions and centuries. Details can conflict without one version being a modern “mistake.” This atlas uses careful language—“in one tradition,” “often associated,” and “later writers”—to preserve that variation.
