An episcopium (Latin for an episcopal palace) is an ecclesiastical figure and their administration. The episcopium emphasizes "an essential unity between his [the bishop's] person, power and place."[1] In medieval Italy episcopia were frequently part of a complex connected to the baptistery and cathedral.[2]
In Rome, the Basilica of St. John Lateran housed the Lateran Palace. This was the principal episcopium of medieval Rome, although Pope John VII (705–707) built an episcopium upon the Palatine Hill.[3]
