Sinbad: The Fifth Voyage synopsis: When I had been a while on shore after my fourth voyage; and when, in my comfort and pleasures and merry-makings and in my rejoicing over my large gains and profits, I had forgotten all I had endured of perils and sufferings, the carnal man was again seized with the longing to travel and to see foreign countries and islands. Soon at sea once more, while passing a desert island Sinbad's crew spots a gigantic egg that Sinbad recognizes as belonging to a roc. Out of curiosity the ship's passengers disembark to view the egg, only to end up breaking it and having the chick inside as a meal. Sinbad immediately recognizes the folly of their behavior and orders all back aboard ship.
However, the infuriated parent rocs soon catch up with the vessel and destroy it by dropping giant boulders they have carried in their talons. Shipwrecked yet again, Sinbad is enslaved by the Old Man of the Sea, who rides on his shoulders with his legs twisted round Sinbad's neck and will not let go, riding him both day and night until Sinbad would welcome death. (Burton's footnote discusses possible origins for the old man—the orang-utan, the Greek triton—and favours the African custom of riding on slaves in this way. This is also reminiscent of an old Indian folktale, Vikram aur Betaal).
Eventually, Sinbad makes wine and tricks the Old Man into drinking some, then Sinbad kills him after he has fallen off and escapes. A ship carries him to the City of the Apes, a place whose inhabitants spend each night in boats off-shore, while their town is abandoned to man-eating apes. Yet through the apes Sinbad recoups his fortune, and so eventually finds a ship which takes him home once more to Baghdad.
