In 146, nearly a hundred years after the ruin of Corinth, Julius Cæsar built it up again in great strength and beauty, and made it the capital of Achaia.  As it stood where the Isthmus was only six miles across, and had a beautiful harbour on each side, travellers who did not wish to go round the dangerous headlands of the Peloponnesus used to land on one side and embark on the other.  Thus Corinth become one of the great stations for troops, and also a mart for all kinds of merchandise, and was always full of strangers, both Greeks and Jews.
