Now as they spoke and urged each other on,
and once more the suitors were plotting certain doom
for the young prince – suddenly, banking high on the left
an omen flew past, an eagle clutching a trembling dove.
And Amphinomus rose in haste to warn them all,
"My friends, we’ll never carry off this plot
to kill the prince. Let’s concentrate on feasting."
– Homer
The Odyssey, Book 20, lines 267-273. As the suitors discuss the killing of Telemachus, their murderous plot is stopped in its tracks by an omen forecasting death and destruction. An eagle flies by with a dove in its jaws. Amphinomus at once recognizes the warning and urges them to abandon their plot and just carry on feasting. But it is too late, as their own doom is foreshadowed here.
