Well, one or two have come close, but not close enough - though I suppose it's possible that the object
had more than one use.
Frank, your girlfriend it lucky to be excavating at
Gadara (Umm Qais). You will probably know that the city was built on a promontory overlooking Lake
Tiberius (Sea of Galilee) and the Golan Heights and the views are just
superb. You can tell her that the object is alongside the main street.
I found the answer to my question in this photo I took at
Gerasa (
Jerash).
Gerasa ("Pompeii of the east") is high in the mountains between
Gadara and
Philadelphia (Amman). All were
Roman cities of the
Decapolis (10 cities) and they all issued coins! They seem to have been very big on columns in that
part of the world - which was tempting
fate, since there have been several major earthquakes in the last two thousand years.
