What started these South Sea islanders off on their career of civilizing the central part of the Americas? Where did they get some of the traits and some of the physical features that Melanesians and Polynesians do not now possess, as well as their inventive brains? Here Gladwin has a startling and fabulous theory to put forward. Here is where Alexander the Great and his sailors and ships come in. Dead Alexander Invades America [Illustration: BEARDED WHITE GODS? _Middle American portraits of men who, unlike the generality of Mongoloids, wore beards.

Lower left, a pottery head found at Tres Zapotes, Veracruz. Lower right, a carving on a stela at La Venta, which appears to have an artificial beard such as was worn by the Egyptians. (The first three, after Vaillant, 1931; the fourth, after Stirling, 1940; the last, after Covarrubias, 1946.)_] Before Alexander died in 323 B.C. he brought 5,000 Levantine and Greek shipwrights and sailors to the Persian Gulf and built a navy of 800 vessels. We hear a good deal about what his army did after his death, of the quarrels of generals and the dissipation of their forces—but not a word about the 5,000 nautical men or their fleet. As Gladwin points out, it is hard to imagine that sailors with sound vessels under them would take shore leave and walk home to Greece. If they sailed away from the Persian Gulf, which way would they have gone? They would hardly have sailed southwestward along the Arabian coast; for Alexander died at a season when the winds would have been against them, and the coast is lacking in fresh water and harbors at any time. A southeastward voyage would have been another matter. The wind would have been behind them, and they had already found the coast attractive in that direction. With this much to go upon, Gladwin sends the fleet of the dead Alexander down the coast of India, past the Spice Islands, and out through Melanesia, Micronesia, and Polynesia. On the way the fleet picks up men and women of various races, and stimulates the whole South Seas into a navigating era. The end result is another discovery of America. It is a discovery by a varied and talented people. Along with the Melanesian-Carib and Polynesian-Arawak, the fleet of Gladwin and Alexander finally brings to our western shores those bearded white men with civilizing propensities who are found in the legends of the Toltec and Maya and the peoples of Colombia and Peru. They it is who teach the Mongoloids how to build stone edifices, work metals, weave textiles, and make fine pots. Gladwin documents all this assiduously and even goes to his opponents for evidence.
