The 'isthmus of Corinth' is the narrow landbridge which connects the
Peloponnese peninsula with the mainland of
Greece, near the city of
Corinth. The word "isthmus" comes from the
Ancient Greek word for "neck" and refers to the narrowness of the land. To the west of the Isthmus is the
Gulf of Corinth, to the east the
Saronic Gulf. Since
1893 the
Corinth Canal has run through the 6.3 km Isthmus, effectively making the Peloponnese an island.
The idea for a way for boats around the
Peloponnese was long considered by
the Ancient Greeks.
The first attempt to build a canal at the place was carried out by the tyrant Periander or Periandros in 7th century BC. He abandoned the project due to its technical difficulties, and instead constructed a simpler and less costly overland stone ramp, named
Diolkos, as a
portage road. Remnants of Diolkos still exist today next to the modern canal.
When the
Roman republic, later
The Roman Empire took control of Greece a number of different soloutions were tried. Julius Caesar foresaw the advantages of such a venture for his newly built Colonia laus Iulia Corinthiensis. By the rein of
Tiberius engineers had tried to dig a
canal, but because of a lack of modern equipment were reduced to using an
Ancient Egyptian invention of rolling the boats on logs as the Egyptians rolled blocks of granite to make their pyramids, which was in use by AD
32.In A.D. 67, the philhellene Roman emperor
Nero ordered 6,000 slaves to dig a canal with spades. The following year Nero died, and his successor
Galba abandoned the project, since it appeared too expensive to him.
