ABSTRACT
In the summer of AD 43, the independent Celtic kingdoms of Britain were confronted by an invasion force of some forty thousand armed men together with their various camp followers.1 Apart from various political and military factors this force was the cultural spearhead of a process we call ‘Romanisation’, and it would thus be very interesting to know something of the religious attitudes prevalent amongst the troops massed at Boulogne (Dio LX, 19). Unfortunately we are not well-informed, but the fact that the troops mutinied at the idea of crossing the sea is significant, for it sets the limits of their horizons, literally.
