I have come across a gorgeous 16th century book showing coats of arms and was stunned by this picture’
The Coat of Arms of Prester John – The Grand Kahn – Batu Khan – Ivan Kalita – Ivan Danilovich.
Ivan Kalita began the huge expansion of the Empire of Tartary.
Here are a few other Coats of Arms.

Arms of the King of Jerusalem (?)

Kings of Panonia and Leon
Aren’t they beautiful?
