[00:00:00]When you hear the word testudo, you probably think of this, the famous Roman battlefield formation where soldiers locked shields together to create protection from missiles. And that makes sense because testudo literally means tortoise. [music] Roman soldiers advancing beneath overlapping shields looking rather like a moving shell. But here's the interesting part.

[00:00:29]Protective coverings shielding soldiers, including structures sheltering battering rams as they attacked enemy walls, could also be called testudo.

[00:00:40]Once again, the same idea appears, men advancing beneath a protective shell.
