The half-arcaded pool - f78v

[Jorge_Stolfi]

I am not convinced that there is any reliable way to measure the length of time that passed between those events.

The "only bit of evidence" I mentioned was on You are not allowed to view links. Register or Login to view. [IIRC].  Microscopic examination, including by Rene, shows that the green pigment lies on top of the ink of the folio number.  That is evidence (if not proof) that the painting occurred after the folios were numbered.  And those numbers must be rather late, both because of their style and because the folios were nested and numbered in the wrong order.

All the best, --stolfi
