The building remains in the picture belong to the presumed Tomb of Luke in Ephesus. The column bases with their capitals, placed upside-down, are part of a circular building that dates to the second century AD. It was built over the remains of an earlier building, but its function is unknown.
Later, in the 5th or 6th century, the structure was turned into a church. During excavations in the 19th century, a pillar with the relief of a cross and a bull were found. The bull was the third of the four faces of the winged creatures described in Ezekiel 1.10. As Luke’s gospel is the third, the representation of the bull was transferred to this gospel in early Christian symbology.
There is no proof, however, of any connection between these building remains and the place where Luke is buried.
