"Irises at Yatsuhashi" (Eight Bridges) by Ogata Kōrin
Ogata Kōrin (1658–1716) turned to a painter at the age of 35. And he succeeded the art style of Tawaraya Sōtatsu (c. 1570–c. 1640). Kōrin became an official painter of the court in 1701. This picture is just after the honor.
It is a work in which the irises were drawn on a golden screen. This elegant flower painting is a design that had been from the Muromachi Period as a motif to recall a scene of Ise-Monogatari, and he also used it for the lacquer work and inkstone before the folding screen.
The mineral pigments were used for coloring in blue(ultramarine) and green (verditer) which clearly appears in the golden background.
You may think that each plant are drawn in a plane. However, when looking at the whole from a little far away, you would notice that irises are lined up in three dimensions.
