Probably also worth noting this is the only green paint on the page (80r)
On 80v, green is seen with the "fighting nymphs", the less than healthy looking animal and the three nymphs bottom left, who I only just noticed are missing limbs (/hands)..
The idea also makes the "green water" images on 79r and 79v interesting
As with anything VM.. pinch of salt and all that, but thought worthy of note.
