Book Summary

The Horse's Mouth is a portrait of an artistic temperament.  Its principal character, Gulley Jimson, is an impoverished painter who bothers little about the customary obligations and decencies.  But although he is a bad citizen he is a good artist, so wholly preoccupied with his art that he is unwilling to endure any privation for its sake.  Gulley Jimson, however, is no self-conscious martyr.  He is so wholly allergic to conventional values as to find a sardonic delight in flouting them, and the only morality he practices is the devotion he gives to painting.  It was the third volume in a trilogy that included Herself Surprised (1941) and To Be a Pilgrim (1942).
