These are
Roman lead
votive mirrors dating to the 2nd to 3rd centuries.
The decoration is full wavy lines and tendrils but is not
writing.
Some of these originally
had a small piece of
glass in the centre but many (most ??) did not. As
votive items (offered at sacred sites like shrines and temples and wells) they did not have to actually
work, they were a symbolic offering.
