Why the Picture?

Romulus and Remus counted vultures, not the Eagles of Jupiter. It's a little piece of dramatic foreshadowing. Remus saw 6 (or 8) and then Romulus saw 12 (or 16). Remus said he won since he saw them first, Romulus said he won because he saw twice as many.

Both right, both wrong.

Remus and his followers come down from the Aventine and make their way to the Palatine to dispute the issue. In the resulting melee Remus is killed - "There is a storm of blows, Remus fell".

So the vultures, who appeared on spec, predicted correctly and wound up with a meal.

This is going to end up in my thesis word for word. Thanks Pooya.
