The cult of Saints was, as throughout Christian lands, of great importance in later Pictland. While kings might patronise great Saints, such as Saint Peter in the case of Nechtan, and perhaps Saint Andrew in the case of the second Óengus mac Fergusa, many lesser Saints, some now obscure, were important. The Pictish Saint Drostan appears to have had a wide following in the north in earlier times, although he was all but forgotten by the 12th century. Saint Serf of Culross was associated with Nechtan's brother Bridei. It appears, as is well known in later times, that noble kin groups had their own patron saints, and their own churches or abbeys.
