About a third of the pictures originally belonged in four series, and are best understood as parts of a series. The rest (the majority) come under Abstract and Miscellaneous or other Categories (see Category menu in sidebar) and stand alone.
The series,
-The Tree as a Symbol
-A City Called Life
-The Tangled Garden,
shown on the dropdown pages below this on the top menu, may also be found under the Categories menu on the right side.
– Mandalas not actually a series, also have a “category” since there are quite a few.
NB: Several other pictures of trees, which are not in the Tree as Symbol series, are under Trees Not in Series in Categories _
