With a big-R, it’s a philosophical and artistic movement that served as a counterweight to the Enlightenment by advocating for Idealism (versus Materialism) and spirituality (if not necessarily religiosity.)

Being thirsty,
I filled a cup with water,
And, behold! -- Fuji-yama lay upon the water,
Like a dropped leaf!
I see Dragons on the walls
Of temples and market stalls.
From Shanghai to London way,
I've seen them by night and day.
I've seen them skewered by St. George
And belching flame like a forge.
I saw one once in Baku,
But never saw one in a Zoo.
