MDDM 35 Herodot

[Otto]

"Almost all the names of the gods came into Greece from Egypt. My
inquiries prove that they were all derived from a foreign source,
and my opinion is that Egypt furnished the greater number. For with
the exception of Neptune and the Dioscuri, whom I mentioned above, and
Juno, Vesta, Themis, the Graces, and the Nereids, the other gods
have been known from time immemorial in Egypt. This I assert on the
authority of the Egyptians themselves. The gods, with whose names they
profess themselves unacquainted, the Greeks received, I believe,
from the Pelasgi, except Neptune. Of him they got their knowledge from
the Libyans, by whom he has been always honoured, and who were
anciently the only people that had a god of the name. The Egyptians
differ from the Greeks also in paying no divine honours to heroes."

"The ceremonies at the feast of Isis in the city of Busiris have
been already spoken of. It is there that the whole multitude, both
of men and women, many thousands in number, beat themselves at the
close of the sacrifice, in honour of a god, whose name a religious
scruple forbids me to mention." 

"(...) this is done at the season when the Egyptians beat themselves in
honour of one of their gods, whose name I am unwilling to mention in
connection with such a matter."

But which god is it?
