Pierrot is a stock character of pantomime and Commedia dell’Arte whose origins are in the late seventeenth-century Italian troupe of players performing in Paris and known as the Comédie-Italienne. His character in postmodern popular culture—in poetry, fiction, the visual arts, as well as works for the stage, screen, and concert hall—is that of the sad clown, pining for love of Columbine, who usually breaks his heart and leaves him for Harlequin. (...) The defining characteristic of Pierrot is his naïveté: he is seen as a fool, always the butt of pranks, yet nonetheless trusting. Especially after his appropriation by the late nineteenth-century Symbolist poets, he is also portrayed as almost tragically moonstruck, distant from and oblivious to reality.

"I am not a sad clown. I am not a sad clown."
(Nathan Lane)
Clown In The Moon
My tears are like the quiet drift
Of petals from some magic rose;
And all my grief flows from the rift
Of unremembered skies and snows.
I think, that if I touched the earth,
It would crumble;
It is so sad and beautiful,
So tremulously like a dream.
Dylan Thomas
