The Ten Oxherding Pictures Square Wall Clock

A series of ten images, generally known in English as the Ox-herding (or Bull-herding or Ten Bulls) pictures, by the 15th century Japanese Rinzai Zen monk Shubun. They are said to be copies of originals, now lost, traditionally attributed to Kakuan, a 12th century Chinese Zen Master. Ten Ox Herding Pictures is, in the tradition of Zen Buddhism, a series of short poems and accompanying pictures that are intended to illustrate the stages of a Mahāyāna Buddhist practitioner's progression towards enlightenment, as well as his or her subsequent perfection of wisdom.
