When there was a ritual sacrifice of an animal (or of a human), the way in which the blood dripped from the altar was often considered by the priest/soothsayer. Divining in this way was known as dririmancy. This form of divination might also be employed on the battle field. Dririmancy was a form of haemotomancy.
