The black pigeons of Dodona.
Two black pigeons, we are told, took their flight from Thebes, in
Egypt; one flew to Libya, and the other to Dodona, in Greece. On the
spot where the former alighted, the temple of Jupiter Ammon was
erected; in the place where the other settled, the oracle of Jupiter
was established, and there the responses were made by the balck pigeons
that inhabited the surrounding groves. This fable is probably based on
a pun upon the word pelciai, which usually means “old women,” but in the dialect of the Epirots signifies pigeons or doves.

Flocks of wild pigeons presage the pestilence,
at least in Louisiana. Longfellow says they come with “naught in
their craws but an acorn.” (Evangeline.)
