Who is Agenor?

Agenor was Pierre Bonnard's fish. And he was the star of a particular Bonnard painting that depicted his (Agenor's -- though Bonnard's too) koi pond. Since Bonnard was a good neighbor of Monet, the koi pond might have been Bonnard's way of paying homage to the older, more famous artist. In any case, I paid my own homage to Bonnard by making his fish the chief actor of my painting. And I added some friends (care of the U.S. Arboretum).
