The resemblance between the cross-shaped tunic and the Vimose coat of mail is no coincidence.
It is very probable that in antiquity the coat of mail was not seen merely as a piece of
armour, but as a tunic in its own right, albeit one that offered protection to its wearer. There is
some literary support for this suggestion. Varro, who wrote in the 1st century BC, speaks of ex
anulis ferrea tunica, or the ‘iron tunic made of rings’, to refer to the mail coat when he is explaining
the etymological origin of the word for cuirass (lorica). This author, then, confirms
that the mail coat was perceived as a tunic. Varro, De lingua latina, V.24.
