or Caetra (καιτρέα, καίτρα). A small
round shield made of ox-hide, and forming a part of the defensive armour of the Osci. (See
Soldiers with Cetrae. (From a MS. of Prudentius.)
It was also worn by the Spaniards and Mauretanians, and by the natives of Britain
It does not appear that the Romans ever wore the cetra. Livy compares it to the pelta of the Greeks and Macedonians, which was also a small light shield.
