I’ve walked in that tunnel and one can clearly see where the two digging crews met. They weren’t off by much. Very impressive!

I can image Eupalinos smiling and say: «Trust me. I am engineer» Other: «Are you sure?» Eupalinos: «I calculated it»

This was an excellent method of tunneling until Hermot the Turk (396-325 BCE) created the Ararat tunnel using trained mining weasels (Mustelidae rapidae undergroundum.) 3,500 males at the west end and 2,000 females at the east. Significant cleanup required.

In the 19th century, the North British Railway built a tunnel with a kink in it. Due to a disagreement between the contractors involved, the two halves pointed at different angles when they met up.

Hmm with a good enough mirror (maybe made of bronze?) and a big fire for light and/or maybe the sun, depending on the orientation and how good the mirror is, I can think of a good way to align things more precisely. Did they have mirrors good enough?

If the map north is up, the tunnel seems to be nw-sw, 45 degrees inclination from the sun. That plus a couple of rotatable mirrors, one for the tunnel one on top of the mountain could do thd trick.
