"Matthijs started with the left eye, which - since he painted the portrait à trois quarts - is about the center of the bud. The [left] eye finished, he started to paint around it the details of forehead, nose, the right eye, the mouth, etc.. ..until he finally enclosed all of these with the contour of the head and the light-brown background. (translation from original Dutch, Fons Heijnsbroek, 2018)"
