Not just a historic but a prehistoric line, Aegaeon Lines of Kourtzis. I have no idea where I got this ad, but I am sure it was somewhere on the Web. And it is pre-1908.

I love all the routes but especially the one from Trieste to Trapezous:
Trapezous, Kallipolis, Ellispontos, Mytilene, Smyrna, Chios, Tsesmes, Piraeus, Gytheion, Kalamae, Patras, Corfu, Trieste!!! This is a route to drive nationalists nuts!
