Neptune's trident

The trident of Poseidon and his Roman equivalent, Neptune, has been their traditional divine attribute featured in many ancient depictions. In Hesiod's account, Poseidon's trident was crafted by the three Cyclopes. According to Robert Graves, however, both Poseidon's trident and Zeus' thunderbolt were originally a sacred labrys, but later distinguished from each other when Poseidon became god of the sea, while Zeus claimed the right to the thunderbolt. In another view shared by Friedrich Wieseler, E. M. W. Tillyard and several other researchers, Poseidon's trident is a fish spear, typical for coast-dwelling Greeks. In that sense it resembles the arrow-headed pronged fork, used by the Mediterranean fishermen to catch eels. Poseidon became particularly worshipped in coastal countries, where fish formed a basic commodity of trade. According to competing proposal by H. B. Walters, Poseidon's trident is derived from Zeus' lotus sceptre, with Poseidon being Zeus in his marine aspect.

In Greek myths, Poseidon wields his trident on a number of occasions. During the contest with Athena over the possession of Attica, Poseidon strikes the Acropolis with the trident to produce a well of seawater. In a similar myth Poseidon strikes the ground with trident to produce a horse for mankind, while his rival Athena produces an olive tree. The oldest coins of Poseidonia from the 6th century BC depict trident wielded by Poseidon in his right hand, similar to Zeus's thunderbolt. An Attic red figure kylix from c. 475 BC depicts Poseidon killing the Giant Polybotes with his trident. In another myth, Poseidon creates a spring or springs with the strike of his trident to reward Amymone for her encounter with him. In a version of another myth Poseidon wields his trident to scare off a satyr who tries to rape Amymone after she mistakenly hits him with a hunting spear. There is also a myth where Poseidon touches the island of Delos with his trident, affixing it firmly to the sea floor. Another myth tells how Poseidon, enraged by sacrilegious behavior of Ajax the Lesser, splits with trident the rock to which Ajax was clinging. While visiting Athens, geographer Pausanias was shown within the Erechtheion the alleged print of Poseidon's trident on a rock and related sea well which, he writes, gave forth the sound of waves when the south wind blew.
