Asbamaeus
A surname of Zeus, the protector of the sanctity of oaths. It was derived from a well, Asbamaeon near Tyana, in Cappadocia, the water of which was said to be beneficial and pleasant to honest persons, but pestilential to those who were guilty of perjury. When perjured persons drank of the water, it produced a disease of the eyes, dropsy, and lameness, so that the guilty persons were unable to walk away from the well, and were obliged to own their crime. (Philostratus; Pseudo-Aristot. Mirab. Auscult; Ammianus Marcellinus)
From Smith's Dictionary of Greek and Roman Biography and MythologyFrom The Roman History of Ammianus Marcellinus
Also at the temple of Jupiter Asbamaeus in Cappadocia, where that famous philosopher Apollonius is said to have been born near the town of Tyana, a spring may be seen, flowing from a pool, which now is filled with an abundance of water, and again sucks itself back, and so never swells beyond its banks.
