we indeed know that griffin is one of the sumbols we find in roman / byzantine tradition as also to the previous ancient greek one.
As the lion was traditionally considered the king of the beasts and the eagle was the king of the birds, the griffin was thought to be an especially powerful and majestic creature. The griffin was also thought of as king of the creatures.
so this symbol can be found in Roman [byzantine] flags, in emperial, in official and private clothes [possible also to cloth covers of horses], as a decoration in palaces/houses, as a jewel , in relegious, imperial and private sculpture and painting etc

Panel with a Griffin, 1250–1300
Byzantine; Possibly from Greece or the Balkans
In the ancient world, the mythical beasts called griffins were symbols of royalty and protectors of the dead. They continued to play these roles for Christians. A legend popular in the Byzantine era told of griffins carrying Alexander the Great through the heavens so he could view his vast realm. Carved griffins such as the one illustrated here are found on later Byzantine tombs, where they may have been placed to identify the dead of royal status and to afford them protection. The design of the relief is similar to patterns on Byzantine silks.

So i reapeat the mention of okamido:
Griffones is a ...corruption of Greek, by which the inhabitants of Sicily Crete, and Calabria were generally known, and despised by, the Crusaders. .....
as also he mention, and i copy from the 'Notes and Queries ' :
.....King Richard had expended great labour and diligense in erecting a castle to which he gave the name of Mate Griffin; at which the Griffones were very much exasperated...........
Speaking of the people of Cyprus.......All those who put to shore in safety, the Griffones stripped of their arms........The King ....boldly attacked the Griffones.........
so as we see Roman/byzantine used this symbol to Roman/byzantine flags, imperial official and private clothing, jewells etc as also as Roman/byzantine relegious symbols, gives a medieval portrait of Roman/byzantine symbolism, which was used as a description term from Crussaders.
