Old Man of the Sea

Old Man of the Sea
In Greek mythology, the Old Man of the Sea was a figure who could be identified as any of several water-gods, generally Nereus or Proteus, but also Triton, Pontus, Phorcys or Glaucus. He is the father of Thetis (the mother of Achilles).
Mythology
In book 4 of Homer's Odyssey, Menelaus recounts to Telemachus his journey home, and how he had to seek the advice of the Old Man of the Sea. The Old Man can answer any questions if captured, but capturing him means holding on as he changes from one form to another. Menelaus captured him, and during the course of questioning, asked if Telemachus' father Odysseus was still alive.
Sinbad
Sinbad the Sailor encountered the monstrous Old Man of the Sea on his fifth voyage. The Old Man of the Sea in the Sinbad tales was said to trick a traveller into letting him ride on his shoulders while the traveller transported him across a stream. However, the Old Man would then not release his grip, forcing his victim to transport him wherever he pleased and allowing his victim little rest. The Old Man's victims all eventually died of this miserable treatment, with the Old Man either eating them or else robbing them. Sinbad, however, after getting the Old Man drunk with wine, was able to shake him off and kill him.
References in poetry
The Old Man of the Sea is alluded to in Edwin Arlington Robinson's book-length narrative poem King Jasper. In part 3 of the poem, King Jasper dreams of his deceased friend Hebron (whom Jasper betrayed) riding on his back. "You cannot fall yet, and I'm riding nicely," Hebron tells Jasper. "If only we might have the sight of water, / We'd say that I'm the Old Man of the Sea, / And you Sinbad the Sailor." Hebron then turns to gold (a symbol of Jasper's motivation for betraying him) and coaxes Jasper to leap across a ravine with the heavy, golden Hebron on his back.
The Old Man of the Sea also figures in the poetry of West Indian poet Derek Walcott. In a 1965 paper, "The Figure of Crusoe", writing about the poem "Crusoe's Journal", Walcott notes:
Referencing the figures of Adam, Christofer (Columbus) and Friday in succession, the poem's narrator remarks, "All shapes, all objects multiplied from his,/our ocean's Proteus;/in childhood, his derelict's old age/was like a god's."
