Another tent picture

I don't know the exact source of this picture, but it looks 14th century to me. It shows parts of four tents (one circular, three rectangular), decorated variously with circles and fringes, and with "crow's-foot" guy ropes emerging from grommets, possibly metal, in the tent wall just below the shoulder. In the foreground, two fashionably-dressed gentlemen in tights and fur-lined mantles sit on benches playing chess while two military men (one in articulated plate armor, one in a quilted arming-coat) and a horse (note the curious straps around its chest) look on.

Thanks to Bob Charrette, who found this picture.
