See which awesome beauty found.
In 3-4 centuries AD. In the late Roman Empire, a fashion appeared on this type of art - Chrysiography.
They painted with gravestone gold on the glass (and covered it from above the second glass, melting them). Very often it was done on the bottoms of drinking vessels, and usually it was portrait images, apparently, who was done by this gift.
In something, it is still steeper than Fayum portraits.
Medallion from Brescia (considered a portrait of Galla Plakida), 3rd century, 6 cm in diameter
The medallion from Brescia in the Middle Ages was mounted in the "Cross of Sv. Dezerria" and preserved.
Here it is, at the bottom
So-called Medallion from Arezzo, 200-250, 4.4 cm
I came across the reproductions of some of these things before, but never paid attention to the technique. Especially on such a striking and painstaking. Just a miracle that it has survived to this day. (Oh yeah, sorry, I forgot that I will write smart people in the comments: this is all the fakes of our days, or the aliens did, yes).
2nd floor. 3rd century. 4 cm in diameter
The beginning of the 4th century. 4.8 cm in diameter (see what a sharp degradation of style compared to the previous one)
3rd century, 4.9 cm
In general, they are all about one era and one size (much less than in the photo). Labor is lazy to sign me.
On the medallions sometimes written names, and sometimes it is not clear that.
So-called "Medallion Evsevia"
In general, in real life it resembles such large buttons, plaques.
But look, for comparison, the 19th century fakes, when the masters have learned something like this again. Then she rolled as originals (since the paradise of people about the ancient monuments was small), now it is immediately visible to romantic and historians.
