Travelling Festivals in Late Antiquity: How Christmas Came to the Greek East

This article argues that the liturgical tradition of celebrating Christmas on 25 December travelled from the Latin West to the Greek East at the behest of Theodosius I upon his arrival in Constantinople in AD 380. From there it made its way to Cappadocia, Pontus and Syrian Antioch by means of travelling clerics who belonged to a pro-Nicene network. The essay also makes the larger methodological point that in late antiquity liturgical traditions did not travel of their own accord; rather, they were often carried by networks of travelling bishops and ‘radiated out’ from major sees to minor ones.
