It seems that I did this copy of a portrait from the Zuishin Teiki emaki back in June of 2019, but never bothered to scan it in.
This emaki (illustrated scroll) presents portraits of the members of the Imperial Guard Cavalry, and is representative of the highly realistic “documentary” style of emaki that flourished in the Kamakura period.
It is interesting because although this emaki is from the time period when the black-and-white hakubyou style was the dominant expression of Yamato-e, it has light washes of color on the clothing of the rider and the tack of the horse.
I have exaggerated the coloring on this copy, but left the horse pure white.
