Technique and condition
attached to an expandable stretcher with ferrous tacks around the tacking margins, which are probably not original as there is an earlier set of tacking holes at all four edges. The canvas used was commercially primed probably with an initial animal glue size layer followed by a pigmented layer consisting mainly of lead white in oil.
The oil paint was applied exclusively by brush in a rather loose manner using mainly single layers of paint, apart from the edges of the forms where there is often a slight overlap. The paint is predominantly opaque and covers most of the stretched face of the canvas, although it also extends slightly around the turnover edges on the left and right sides. In some areas there is no paint application and the white ground is the layer that is seen, for example in the area underneath the man's right arm who sits on the bridge in the foreground or the base of the bridge railings at the bottom right corner. Most paint layers are fairly thin and the canvas weave texture is therefore apparent through them. However, in some areas a reasonable impasto is used, for example in some of the details of the boat and the two figures on the right by the canal side.
The work is not varnished and the paint surface is typically matt. On acquisition it was noted that at some point the painting had been removed from its stretcher, the stretcher expanded on the left and right sides and the painting then restretched back onto it, so that all areas of paint became visible from the front. Unfortunately this resulted in an excessively and unevenly expanded stretcher which had little rigidity and was no longer rectangular in shape. The stretcher was therefore returned to its original dimensions by closing up the corners and now provides reasonable support to the painting. In addition a thick and extremely disfiguring layer of surface dirt was removed from the paint surface and a frame was constructed. The frame is glazed, has a backboard and provides satisfactory protection to the painting.
