Quote from : Rome: The Eagle of the Twelfth Book

The camp offices stood in the centre, adjoining the shrine to Jupiter that held the legion’s Eagle. In the camps of the Vth Macedonica and the VIth Ferrata, these buildings were of grey stone, dressed by Gaulish masons to such smoothness that a man could run his hand down them and not feel the joins. The legions’ respective signs of the bull and the eagle had been carved thereon with such pride and perfection that men copied them on their shields and carved them on the bedheads in the barracks. At Raphana, the camp office of the XIIth Fulminata and IVth Scythians before which we dismounted was built of the local baked mud, and some drunkard with a poor eye for detail had etched the Scythians’ sign of the goat and the Fulminata’s crossed thunderbolts together, so that it seemed as if the goat were thunderstruck, or else that lightning grew from its anus. Both applied equally; each was unthinkable in a legion which had any pride in itself.
