Roman Armor

[Tarbicus]

I don't think there is any evidence that the pomerium was supposed to keep all weapons outside of the city. It was about the arma/toga distinction.

How does that explain taking weapons inside the pomerium was a blasphemy? I'm fairly certain Caesar's murderers were wearing togas at the time. Had they done the deed inside the pomerium they'd have been charged with blasphemy. Not for murder, but for carrying weapons inside the pomerium.
