Hi Joe,
I have a list (somewhere) of a large number of ancient river-gods from
Asia-Minor as depicted on coins (mostly the reclining
type, rather than
the man-headed
bull types).
It is fairly comprehensive, but may not be
complete. I recall compiling it
from three or four sources, and have added pretty much anything new
that I have come across since.
I
had planned to do some sort of article/listing some time, but have
had other matters take precedent.
That may be a useful start. The modern names are another thing, a far
greater task I expect.
