Roman cavesson

Salve,
time again I will return to my visit to Mainz archaeological museum, where I saw some surviving first class Roman cavalry harness.
They have on display two fragments of such cavessons as used by the Roman cavalry. I have seen a name 'psalion' used in the academic literature for this type of cavesson.
As usual the Comitatus website is a good place to start your reading on the Roman cavalry reconstruction and reenactment.

Roman military artifacts has some great photos of the cavessons used by the Romans.
Roman Coins page has some first rate images of the Roman cavalry harness and  armour.

 Finally, Roman Army Talk has a discussion on the Roman cavalry horse tack.
enjoy
