[Ruby Novacna]

the eagle was an ancient Illyrian symbol

Thank you, Cvetka for the images, unfortunately I don't see their dates. My question was just about the possible identification of the date of the image, based on the position of the feathers of our "eagle".

The VMs roots look more like a pair of wings

Eagle or pair of wings, what matters in my question is the position of its feathers to try to determine the date of the image. However, this is clearly not a vol.

Given a context of alpine northern Italy the obvious heraldry suggested by the "eagle" motif is the coat of arms of County Tyrol. The original coat of arms is still to be seen on the altar at Tyrol Castle circa 1370s.

The Tyrolean eagle is red, why should the colours be reversed?
Besides that, there are other root animals in the manuscript, why rely only on the eagle? I think Nick was talking about these images in his book.
