Although particularly associated with the Romans, aqueducts were devised much earlier in Greece, the Near East, Nile Valley, and Indian subcontinent, where peoples such as the Egyptians and Harappans built sophisticated irrigation systems.

Notan is the underlying abstract framework of dark and light values, upon which you build the value structure of a painting. The arrangement of darks, lights, and grays, regardless of the colors used, creates an impression of beauty. It derives from two words that refer to the amount of ink you use for a pen and ink wash drawing. Nong( 浓 ) meaning thick, strong, concentrated, and Dan (淡) means weak, watery. Hence, the term ‘Notan’ literally means concentrated/weak.”
