Carrington's art often depicts horses, as in her "Self-Portrait (Inn of the Dawn Horse)" and the painting "The Horses of Lord Candlestick". Her fascination with drawing horses began in her childhood. Horses also appear in her writings. In her first published short story, "The House of Fear", Carrington portrays a horse in the role of a psychic guide to a young heroine. In 1935, Carrington's first essay, "Jezzamathatics or Introduction to the Wonderful Process of Painting", was published before her story "The Seventh Horse". Carrington often used codes of words to dictate interpretation in her artwork. "Candlestick" is a code that she commonly used to represent her family, and the word "lord" for her father.
