Cosmas Indicopleustes (i.e. voyager to India), an Egyptian monk of the 6th century, born in Alexandria, singular for his theory of the system of the world, which, in opposition to the Ptolemaic system, he viewed as in shape like that of the Jewish Tabernacle, with Eden outside, and encircled by the ocean, a theory he advanced as in conformity with Scripture.
