119 The painting „Death of St Joseph“ Preparation The preparation was applied in two layers. The brownish bottom layer is thick, with a very rough granular structure. The upper layer is significantly thinner but irregular, reddish and with a finer granular structure (Fig. 191). On the unaltered horizontal sides, the preparation ends at the front edges of the painting, indicating that the preparation was applied after the stretching of the canvas. Paint layer The paint layer consists of oil colours applied mainly alla prima, executed in a fast, simple, and experienced manner. Glazes could only be observed in the area of the green drapery on the lower left side of the painting. The paint body itself is quite coarse resulting in a very granular appearance of the surface (Fig. 192). Brushstroke marks are clearly visible on a large part of the surface especially in bright areas where the paint layer is thicker and has visible impasto. The areas with figures seem to be of a more elaborate quality than the drapery of the baldachin, clouds, and sky in the background.
