Samos - ANCIENT SAMOS - The tunnel oF Eupalinos (EUPALINEIO ORYGMA) - Problems

Problems

The problems inherent in the decision to begin simultaneously from opposite sides of the mountain in the hope of meeting head-on in the centre, can be summarised as follows. There is no serviceable landmark visible from both entrances to the tunnel. The shape of the mountain does not permit either entrance to be seen from the summit. There were no clocks to verify that a reading of the angle of the sun’s shadow—nature’s most reliable measurement—would be taken simultaneously in two different sides of the hill. There were no compasses or theodolites. And it should be remembered that any measure of direction or level which was made by a series of smaller, repeated measurements over or around the surface of the hill, was always subject to a compounding margin of error with every successive measurement taken, especially over such rough terrain. An error of one degree between the alignments of the trajectories of the two halves of the tunnel would result in a divergence of about 9m at the point where the two tunnels were to meet.

   Given all this, Eupalinos had to ensure three certain ties in his construction: (1) that the angles of the trajectory were the same and perfectly aligned so as to guarantee meeting in the centre; (2) that the two entrances on the opposite sides of the mountain were perforated at exactly the same height above sea level; (3) that the digging maintained both a constant horizontal level and a straight axial line without deviation. An error in any of these would mean failure. Lastly (4), there were purely practical problems, such as the possibility of encounter dangerously unstable rock, or seams of water in the heart of the mountain, which could respectively block or flood the tunnel

access

Samos Island, Greece.

By air: Domestic flights are frequent from Athens – four to five times daily with Olympic Air and twice a day in summer with Aegean Airlines.
There also direct flights by charter from destinations outside Greece.
By boat: Sea access to Samos is also plentiful, but a little confusing because it is split between three separate ports: Karlóvasi and Vathy, on the north coast, for the larger ferries plying the northern and western routes to Piraeus, Chios, Lesbos, Ikaria, Thessaloniki etc;
and Pythagóreio, on the south coast, for the Dodecanese and southern routes,
i.e. the F/B Nisos Kalymnos (4 days per week)
and hydrofoils (daily in summer) to Patmos, Lipsi, Leros, Kalymnos, Kos, and on to Rhodes , with the Nisos Kalymnos stopping at Agathonisi and Arki in addition, before calling at Patmos.
The summer hydrofoil service to Fourni and Ikaria (4 times weekly) also leaves from Pythagóreio. Crossings to Turkey (Kus¸adasi) run daily from Vathy, during the summer season only (Easter to mid October); thereafter more infrequently.

eating

Samos Island, Greece.

In Vathy, Christos (two blocks in from the water-front, and north of the main square) serves Asia Minor specialties, interesting salads, and good, fragrant wine.
The village of Vourliotes has several tavernas offering good mountain food in its picturesque plateia: less contrived, and more popular with islanders, is Pera Vrysi, at the entrance to the village. On the shore below, at Avlákia, the Mezedopoleío "Doña Rosa" has a pleasing touch of eccentricity, but nonetheless prepares excellent Greek dishes with localredients and good presentation.
Further west at Palaio Karlóvasi, the Oinomageireío "Dryousa", in the plateia where the paved road ends, is family run, providing fresh, home cooking.
The last true tavernas in Pythagóreio closed some time ago; the best remaining eatery there, with a pleasant view from its position at the beginning of the harbour mole, is Varka. For sunset views, however, few can match Balkoni tou Aigaiou at the south end of Spatherei;
while the taverna at Koutsi, up and west from Pyrgos, though not remarkable for food, is an unforgettable and cool refuge on a hot day, beside a spring below plane trees in the hills of central Samos .
Pure comb honey of high quality can be found at Melissa – a small supply-shop, a few metres up the main street of Pythagóreio from the harbour.
