Scale is a concept the antiquity of which can hardly be traced.
Certainly the familiar phenomena that accompany sc ale changes in
optical patterns are mentioned in the earliest written records. The
most obvious topological changes such as the creation or
annihilation of details have been a topic to philosophers, artists
and later scientists. This appears to of fascination be the case
for all cultures from which extensive written records exist. For th
instance, chinese 17 c artist manuals remark that "distant faces
have no eyes" . The merging of details is also obvious to many
authors, e. g. , Lucretius mentions the fact that distant islands
look like a single one. The one topo logical event that is (to the
best of my knowledge) mentioned only late (by th John Ruskin in his
"Elements of drawing" of the mid 19 c) is the splitting of a blob
on blurring. The change of images on a gradual increase of resolu
tion has been a recurring theme in the arts (e. g. , the poetic
description of the distant armada in Calderon's The Constant
Prince) and this "mystery" (as Ruskin calls it) is constantly
exploited by painters.
