Valiant and Victorious?

[Tony Riches]

Chaps,

I am curious to be clear as to the meaning of the 'valeria victrix' handle attached to the 20th legion by the time of my fictional 'Empire' series, and in particular the word 'valeria'. Different sources have it translated as:

- Valiant;
- Valerian (apparently the emperor Augustus's main military advisor at the time of the legion's founding was from the Valerii clan, namely Marcus Valerius Messalla Corvinus);
- Black headed eagle (although this is apparently somewhat tenuous).

Any help that anyone can provide would be appreciated. I'm guessing that the scholars are still agreeing to differ, but it's always sensible to ask...

Thanks,

Tony.
