118 The painting „Death of St Joseph“ Technical description Strainer system The painting is mounted on a wooden strainer made of coniferous wood with one horizontal beam in the middle (Fig. 189). The strainer is original. It has undergone small structural changes in order to fit the painting into the decorative frame and niche. Originally the width of the strainer was slightly bigger; the canvas was dismounted along the vertical beams, the width of which was reduced by 1cm or slightly more. Textile support The textile support in plain weave is made from flax (or hemp) and composed of two pieces, joined together with a pronounced horizontal seam running close to the centre of the painting.78 The canvas is brightly coloured and fairly thin, woven relatively evenly and narrowly79 (Fig. 189, 190). The upper tacking margin and the seam have selvedges, indicating that the canvas, which has a loom width of approximately 78cm, was used in horizontal orientation. Original tacking margins are preserved along the horizontal beams. Here the canvas is fixed with the original wooden pegs80 (Fig. 190). Fig. 190: Original mounting of the canvas with wooden pegs
