He is probably alluded to by Virgil, "Eclogue" iii., 41.
(9) Herodotus was less fortunate.

For he says "Concerning the nature of the river I was not able to gain any information either from the priests or others." (ii., 19.) (10) It was supposed that the Sun and Moon and the planets (Saturn, Jupiter, Mars, Mercury, and Venus) were points which restrained the motion of the sky in its revolution.
(See Book VI., 576.) (11) Mercury.

(See Book IX., 777.) (12) That is, at the autumnal equinox.

The priest states that the planet Mercury causes the rise of the Nile.

The passage is difficult to follow; but the idea would seem to be that this god, who controlled the rise and fall of the waves of the sea, also when he was placed directly over the Nile caused the rise of that river.
(13) So also Herodotus, Book ii., 22.
