| Beginning
in the early Renaissance artists kept their informal drawings from nature
and first ideas in sketch books of various sizes. This practice was derived
from the medieval model book, in which artists recorded their finished ideas
for study within their workshops and application in finished works or art.
In the fifteenth century metalpoint and prepared paper were considered the
ideal media for sketch books, but chalks and pen and ink replaced it early
in the sixteenth century, succeeded by the graphite pencil in the nineteenth. |
