An ancient Roman Aucissa bow brooch

Aucissa bow brooch

Aucissa type brooch with the needle sticking out.
Date: circa 50 - 65 AD.

These were imported by the Romans from the continent and are an early example of a hinged pin, sometimes on an iron axis. This brooch type was first made in Gaul during the first half of the 1st century AD, and appeared in Britain.

There is sometimes the word avcissa or atgivios on the head of the brooch which is assumed to be the maker's name. This type is well known on military sites throughout Britain but seems to have been replaced by British made brooches.
