Egg tempera painting technique Catherine of Aragon

Showing all the stages from underpainting to final glazes of the Portrait of an Infanta (Katherine of Aragon, aged 11) by Juan de Flandes, ca 1496. Juan de Flandes (John of Flanders) was court painter to Isabella of Castile. He worked in oil on wood, so my egg tempera copy is not as smooth as the original. Pigments (all natural): flake white, yellow ocher, burnt sienna, lazurite from Afghanistan, vermilion, indigo, light lead tin yellow. With thanks to David Cranswick for excellent tuition.
