In the context of Saint Luke the Evangelist (Master Theodoric), discuss the The results of the technological survey of the painting of the Description and classification.
The construction of the thin beechwood backing board, which is covered with canvas at the joints, is originally from the Netherlands. The technique of execution reveals familiarity with French painting en grissaille, popular in Paris in the mid-14th century. The painting follows a highly detailed and sovereignly executed underdrawing executed with fine strokes. Only the modelling of the face is subject to minor changes. The ground layer consists of lead white on a chalk ground. The colour layer consists of egg tempera interspersed with intermediate layers of walnut oil. These prevented rapid drying and allowed perfect modelling of volumes with thin glaze layers. Theodoric is characterised by the complex construction of the ground and covering colour layers, of which there are usually up to six in the draperies. The painter took care in selecting the grain size of the pigment, achieving high transparency of the layers with the help of an oil binder. The incarnations are usually painted in a single layer and the colours are the result of mixing pigments on the palette.
