133 The painting “Purgatory” of the Mary retable specifically designed for the Mary retable during the assembly of the individual elements. Technical description Mounting The painting fits the space between the two columns of the retable perfectly. The canvas, however, is not mounted on a “classical” strainer or stretcher. Instead, four wooden boards, 30 mm thick and 10 cm in depth are simply nailed together to form a box-like construction. The canvas is nailed to the small front side of this wooden construction (Fig. 204). Textile support The textile support consists of one single woven piece made by flax (or hemp). The weave structure is a plain weave.86 The handwoven textile exhibits several nodes and weaving errors, such as protruding loops of threads. Selvedges do not exist. The canvas is exclusively nailed to the front of the strainer, with nails spaced approx. 10-15 cm apart; the excess fabric has not been folded over but cut off flush.
