Whats’ with the dotted lines across Spain? There was no water route across spain in 325BC, was there?
The Midi canal wasn’t completed until the 17th century, IIRC.
Or do the dotted lines indicated Pytheas just crossed land the usual way?
Just checking his route it doesn't look like he actually went around Scota, just between Scota and Alba ~ again, the same interests that made Galicia so dangerous to Eastern invaders also made Scota dangerous.
Recall what I said about the Gaelic speaker in Galicia (NW Spain) and Scota (Ireland) using Greek as their written language ~ they were in the habit of getting a new Greek to do that writing whenever the old one wore out! (Bwahahahahahahahaha!)
