International Standard Bible Encyclopedia
dam'-a-ris (Damaris, possibly a corruption of damalis, "a heifer"): The name of a female Christian of Athens, converted by Paul's preaching (Ac 17:34). The fact that she is mentioned in this passage together with Dionysius the Areopagite has led some, most probably in error, to regard her as his wife. The singling out of her name with that of Dionysius may indicate some personal or social distinction. Compare Ac 17:12.
