The traditional posture of prayer in medieval Europe is kneeling or supine with clasped hands, in antiquity more typically with raised hands. The early Christian prayer posture was standing, looking up to heaven, with outspread arms and bare head. This is the pre-Christian, pagan prayer posture (except for the bare head, which was prescribed for males in Corinthians 11:4, in Roman paganism, the head had to be covered in prayer). Certain Cretan and Cypriote figures of the Late Bronze Age, with arms raised, have been interpreted as worshippers. Their posture is similar to the "flight" posture, a crouching posture with raised hands, observed in schizophrenic patients and related to the universal "hands up" gesture of surrender. The kneeling posture with clasped hands appears to have been introduced only with the beginning high medieval period, presumably adopted from a gesture of feudal homage.
