Roman Animism
the Roman Eagle (Aquila) was the Divine Standard of it's legion, held in reverence with the other lesser standards in a
special tent but in a central position of honour. It was the soul of the legion, which could not exist without it.
the standard of the 13th legion (Legio XIII Gemina)
it was carried by an Aquilifer, a senior NCO who would be a veteran of many
battles and would defend the Eagle with his life, the british defence of their regimental standards and
the french of their napoleonic 'eagle' is a pale imitation of the Legion's worship.
here is another Aquilifer, wearing a bear's skull/skin over his helmet, standing next to his centurio.
no actual roman eagle has ever been found, the rough depictions in statuary have been used to base construction of replicas like the ones above.
