Several ancient chronicles of the exploits of Alexander the Great depict him encountering creatures that were not entirely Human. These are creatures that modern people would describe as Ape Men.
From Nearchus voyage home [Note]
Alexander only made it into India as far as the regions we now call Pakistan, but further south on the Indian subcontinent is the land in which the Vanara are said to have dwelt. The Vanara ape men were supposedly a semi intelligent Human sub species that figure prominently in Vedic literature. See: The Vanara Ape Men
In his Natural History Pliny the Elder describes a race of silvestres [Which translates to wild], he describes them as creatures in India who had humanoid bodies but a coat of fur, fangs, and no capacity to speak. India in Plinys time was pretty much considered anything East of Persia [Iran]
1. Nearchus' voyage home. When Alexander invaded Asia in May 334 BC, Nearchus accompanied him as his Admiral. He wrote a book about the naval expedition, which was not only a military campaign but voyage of discovery. The book he wrote known as the Indike is lost to the ravages of time. Elements of its content have survived from several sources, in particular the Indike by Arrian of Nicomedia which consists of two books. The first was a description of Indian geography and culture, the second was Nearchus' voyage home. See: Nearchus' voyage home Translation by E. Iliff Robson
2. Historia Alexandri Magni [Histories of Alexander the Great] believed to have been written by a Quintus Curtius Rufus in the First Century AD, whom some scholars believe to be a pseudonym masking another. Later manuscripts attribute its origins to Alexander's court historian Callisthenes, who died before Alexander and could not have possibly written a full account of Alexanders life. The unknown author is sometimes referred to as Pseudo-Callisthenes. Its earliest extant versions are in Greek from the 3rd Century.
