While Braque challenged the need to be figurative, De Chirico challenged the need to have clear meaning altogether.
Up until then, most art had "made sense".
No matter who the artist was, the viewer would have immediately had a sense of what they were trying to represent.
But unlike previous artists, De Chirico was not interested in representing something real or readily accessible.
His paintings act as puzzles - distorting time and space and challenging the viewer to find meaning in them.
For Magritte, seeing De Chirico's paintings was like "seeing thought for the first time".
The painting is a homage to Surrealist poet Apollinaire.
De Chirico had recently moved to Paris and wanted to thank the poet for his support.
The sculpture represents the Greek mythical poet Orpheus.
