Righteousness, from The Five Virtues

Two young male courtesans enjoy reading in their quarters by candlelight. One holds an illustrated book recognizable as the drawing manual Illustrated Book of the Treasure-Bag of Sketches (絵本写宝袋), published in 1720 by Tachibana Morikuni (1679–1748). The poem at the top translates as follows: In all things to be humble, discern the path of reason, and abstain from falsehood. This is what we call righteousness.
