Persian Gulf

Yet the premature hour of the Pequod’s sailing had, perhaps, been correctly selected by Ahab, with a view to this very complexion of things. Because, an interval of three hundred and sixty-five days and nights was before him; an interval which, instead of impatiently enduring ashore, he would spend in a miscellaneous hunt; if by chance the White Whale, spending his vacation in seas far remote from his periodical feeding-grounds, should turn up his wrinkled brow off the Persian Gulf, or in the Bengal Bay, or China Seas, or in any other waters haunted by his race. So that Monsoons, Pampas, Nor’-Westers, Harmattans, Trades; any wind but the Levanter and Simoon, might blow Moby Dick into the devious zig-zag world-circle of the Pequod’s circumnavigating wake.

But was there no other way for the whale to land the prophet within that short distance of Nineveh? Yes. He might have carried him round by the way of the Cape of Good Hope. But not to speak of the passage through the whole length of the Mediterranean, and another passage up the Persian Gulf and Red Sea, such a supposition would involve the complete circumnavigation of all Africa in three days, not to speak of the Tigris waters, near the site of Nineveh, being too shallow for any whale to swim in.
