Text and context

[Aga Tentakulus]

       

If I were to describe the root of the plant, I would assume that it grows rather flat and in all directions. Therefore, I would rather look at the root part from above.

We know that roots were often drawn in a particular shape. Let us think of the mandrake (as a male).
In the Far East it was the ginseng.
On the one hand as a hand and on the other hand the plant was assigned to a part of the body.

So why not an eagle?
But since the eagle was the symbol of the imperial Roman Empire, I would not consider it to be an indication of origin. The empire was not exactly small.
