At the same time, or not much later, a second town grew up on the mainland opposite the isle; and the two together were long regarded as constituting a single city.

After the time of Alexander the continental town went to decay; and the name of Palae-Tyrus was given to it,[415] to distinguish it from the still flourishing city on the island.
The islands of which we have spoken formed a chain running nearly in parallel to the coast.

They were some eleven or twelve in number.

The southern extremity of the chain was formed by three, the northern by seven, small islets.[416] Intermediate between these lay two islands of superior size, which were ultimately converted into one by filling up the channel between them.

A further enlargement was effected by means of substructions thrown out into the sea, probably on two sides, towards the east and towards the south.
