Britain was then under Vettius Bolanus, who governed more mildly than suited so turbulent a province. Agricola moderated his energy and restrained his ardour, that he might not grow too important, for he had learnt to obey, and understood well how to combine expediency with honour. Soon afterwards Britain received for its governor a man of consular rank, Petilius Cerialis. Agricola's merits had now room for display. Cerialis let him share at first indeed only the toils and dangers, but before long the glory of war, often by way of trial putting him in command of part of the army, and sometimes, on the strength of the result, of larger forces. Never to enhance his own renown did Agricola boast of his exploits; he always referred his success, as though he were but an instrument, to his general and director. Thus by his valour in obeying orders and by his modesty of speech he escaped jealousy without losing distinction.
