A Couple of Seals

Hi

I found these two lovely Seals within a month of each other, the first one has a the reverse writtening on it saying 'such are my subjects' and is probably Georgian era.  The lower one is Medieval, 13th century and below is a description of what both was Identified as.

The Georgian one with the chap (George III?) on an unwilling donkey reads "SUCH ARE MY SUB[JEC]TS, some sort of parody of the time.

The medieval (13th Century or thereabouts) one starts "SIGIL ROGERI", the Seal of Roger. The surname could be "CARI"? Cary?

For those who don't know the purpose of the above item, they could be used on a letter or document where wax is melted onto it and then the seal is pressed against the wax so the image then becomes the right way around.  It shows and proves who it is from and that it has not been tampered with and hence sealed.
