（*Kosma=s), commonly called INDICOPLEUSTES (Indian navigator), an Egyptian monk, who flourished in the reign of Justinian, about A. D. 535.
In early life he followed the employment of a merchant, and was extensively engaged in traffic.
He navigated the Red Sea, advanced to India, visited various nations, Ethiopia, Syria, Arabia, Persia, and almost all places of the East. Impelled, as it would appear, more by curiosity than by desire of gain, eager to inspect the habits and manners of distant people, he carried on a commerce amid dangers sufficient to appal the most adventurous.
There is abundant reason for believing, that he was an attentive observer of every thing that met his eye, and that he carefully registered his remarks upon the scenes and objects which presented themselves.
But a migratory life became irksome.
After many years spent in this manner, he bade adieu to worldly occupations, took up his residence in a monastery, and devoted himself to a contemplative life.
