Porta Santa Marble “Quarried on the island of Chois off the west coast of Asia Minor ....Another ancient marble under this name was quarried on the island of Jasus off the coast of Proconnesus, modern Marmora, in the sea of Marmora.” “The general colors of the ancient stone as described by different authors shows a wide range of colors.
