Some Voynichy crowns

[Aga Tentakulus]

Next to the gate, according to the archives, is Albert III, the brother of Rudolf IV. After Rudolf’s death, Albert continued to finance the construction.
To the right is his wife, , the sister of Rudolf’s wife.
I believe Rudolf and his wife are depicted further up (second crown).

Interestingly, there is a statue of Margaret of Luxembourg (Rudolf IV’s mother) in which she is wearing the same crown.

It’s hard to say exactly who is depicted on the gate.
