The article which I linked above provides a survey of the history of tidal concepts from Antiquity to Middle Ages.
I did not find anything of great interest with respect to 67v2 there. But the important thing (and I never thought before in that line) is that tides are weak in the Mediterranean, so I can suppose that anybody including tidal diagrams (implying that tides are a significant factor) would, with good probability, be an observer of the outer Atlantic coast or, at least, an inhabitant of the regions such as France, Spain or England, not e.g. Switzerland or Italy. I wonder what are the places of origin of those MSs that arca_libraria listed.
