 In the Irish tradition there were two types of such "peregrinatio", the "lesser" peregrinatio, involving leaving one's home area but not the island, and the "superior" peregrinatio, which meant leaving Ireland for good.This voluntary exile to spend one's life in a foreign land far from friends and family came to be termed the "white martyrdom".Most "peregrini" or exiles of this type were seeking personal spiritual fulfilment, but many became involved in missionary endeavours.
