This is a hand-colored print from the "Costume Di Moyen Age" series, depicting a Scottish knight.
The title "Chevalier Ecossais" translates to "Scottish Knight." He is shown in traditional Scottish attire, with a distinct tartan pattern that was common in Highland dress. His shield bears a heraldic symbol, and he's equipped with a spear and a sword, which were typical armaments for a knight. The helmet with its unique design might also reflect a particular status or rank. This illustration, like the one of Philippa of Hainaut, serves as a historical reference to the attire and armaments of a Scottish knight during the Middle Ages.
More about the vivid colors of this original hand-colored antique print:
The colors have a nice glow over them. Historically, egg whites, known as glair, and sometimes egg yolk were indeed used in illumination and painting, particularly in manuscripts, to give colors a brighter appearance and to add a sheen or gloss to the work. This technique was quite common during the Middle Ages and into the Renaissance.
Egg whites can be applied as a varnish over pigments to enhance their brightness and to protect the colors. This application could make the colors appear more vivid and also add a slight glossy sheen to the surface of the image.
Egg yolk, on the other hand, was commonly used as a binding agent in paint. It forms the basis of tempera paint, a medium that was widely used before the advent of oil painting. Egg yolk helps to create a durable and long-lasting color that adheres well to various surfaces.
In the context of the print from 1847, it's less likely that egg whites or yolks were used directly on the print, as by that time, commercial printing processes would have been more advanced and less reliant on such manual methods. However, if this print is a representation of an earlier style or is meant to mimic the appearance of hand-painted manuscripts, the original artists might have employed techniques or materials that gave a similar effect to those achieved with egg-based binders and varnishes.
