It became fashionable in the 15th century, with the full development of classical heraldry, to provide attributed arms to saints and other historical characters from the pre-heraldic ages. The widespread attribution to George of the red cross on a white field in Western art – "Saint George's Cross" – probably first arose in Genoa, which had adopted this image for their flag and George as their patron saint in the 12th century. A vexillum beati Georgii is mentioned in the Genovese annals for the year 1198, referring to a red flag with a depiction of George and the dragon.
