Here's a double page from a Flemish Book of Hours that demonstrates several aspect of European culture in the Middle Ages:
ONE) Fantasy Illustration is not a recent innovation
TWO) Other scripts then "GOTHIC" were used.
THREE) Interaction of Illumined Manuscript and Techniques used for larger paintings
Note the use of shadows.
FOUR) Use of workshops there seems to be at three separate "hands" involved on these pages! Possibly four if the calligrapher wasn't one of the other artists.
Or just enjoy the images without analysing them!
