The Cuirass
Also called a pair of curates,
a cuirass is simply a breastplate and backplate designed to be worn together.
Cuirasses were used from at least the 8th century BC on. The muscle cuirass
was most popular in 8th century BC Greece. These cuirasses were made of leather
or bronze and conformed roughly to the shape of the torso muscles. During
the middle ages, the steel plate cuirass was extensively used. Light enough
to wear dismounted, it could also be coupled with other limb plates to form
a complete suit of mounted armor. Seen head on, a cuirass appears to be a
breastplate. The only difference between a breastplate and a cuirass is that
with a cuirass, theres also a backplate you dont necessarily
see.
