Magritte painted the 'Lost Jockey' after seeing de Chirico's painting 'The Song of Love'. Magritte felt that in this painting he had for the first time struck the special poetic and surrealist note that was to become his trademark.
The mobility of horse and jockey is juxtaposed against the immobility of the trees. The starkness of the landscape further adding an eerie effect. At a first glance the scene seems plausible but becomes ridiculously absurd at the second.
