Boötes, in Greek Mythology, the son of Demeter and Iasion, who, being plundered of all his possessions by his brother, invented the plough, and cultivated the soil. He was translated to heaven with the plough and yoke of oxen, under the name of Boötes ('ox-driver'), which is still borne by a constellation beside the Great Bear (or
Wain). According to others, Boötes was the son of Lycaon and Callisto (see URSAMAJOR). The bright star Arcturus is in Boötes.
