Globus cruciger

[Dobri]

Here is an example of royal regalia in folio 72v (Libra), a naked nymph wearing a crown (added later ?) with a distinctive half-arch hoop crown and a small cross on top of it.

Note that a crown of a queen must have the monde (orb) at the top of the crown below the cross.
Either the artist was unaware of this, or the crown was for the consort of a king, or there is some unknown symbolism in the drawing in folio 72v (Libra).
