Gods, Goddesses, and Ancient Legends
Romulus killed his brother on the day Rome was founded. He was deified on the day he disappeared. Both acts expressed the same Martian logic — that order required absolute force, and that force, properly used, was sacred.
Amulius forced Rhea Silvia into the Vestal order to prevent her from producing heirs. She produced Romulus and Remus. Their father was Mars.
The Romans had a word for the advance — and a god for it. Mars Gradivus governed the moment between preparation and battle, when discipline either held or broke.
