Even in 400 BC

Look what I found: a golden Etruscan medallion from around 400 BC featuring Hercules and Iolaus. Unfortunately, Iolaus' face has been smushed. But Hercules has well-defined abs and chest, not to mention a heroically huge nose. And is Iolaus wearing articulated shoulder armor? Did the Etruscans even have articulated armor?

I am so clueless.

On the other hand, I am very sure that Hercules' hand is on Iolaus' thigh.
