Hallowed Een

The feast of All Hallows', on its current date in the Western Church, may be traced to Pope Gregory III's (731–741) founding of an oratory in St Peter's for the relics "of the holy apostles and of all saints, martyrs and confessors".[79][80] In 835, All Hallows' Day was officially switched to 1 November, the same date as Samhain, at the behest of Pope Gregory IV.[81] Some suggest this was due to Celtic influence, while others suggest it was a Germanic idea,[81] although it is claimed that both Germanic and Celtic-speaking peoples commemorated the dead at the beginning of winter.[82] They may have seen it as the most fitting time to do so, as it is a time of 'dying' in nature.[81][82] It is also suggested that the change was made on the "practical grounds that Rome in summer could not accommodate the great number of pilgrims who flocked to it", and perhaps because of public health considerations regarding Roman Fever – a disease that claimed a number of lives during the sultry summers of the region.
