For the benefit of pseudo-scholar who claims that ancient Tyre is submerged under the sea and that the present-day city of Tyre is not located at the ancient site, I provide the following map with overlaps the two graphics provided in Marriner's article:
I highlight the coastlines as follows: in red I give the coastline of ancient Tyre as it was in Phoenician times. In blue I give the coastline of present-day Tyre. And in orange I give the ancient coastline of the mainland. And in pink I've highlighted the part of ancient Tyre that is still presently not submerged and which is presently occupied and urbanized to this day. Even part of the ancient harbor today has buildings on it.
Here is the description of Tyre in Roman times; note how it mentions how the city "restored itself" after the desolation of Alexander:
"Tyre is wholly an island, being built up nearly in the same way as Aradus; and it is connected with the mainland by a mole, which was constructed by Alexander when he was besieging it; and it has two harbours, one that can be closed and the other, called "Aegyptian" harbour, open. The houses here, it is said, have many stories, even more than the houses at Rome, and on this account, when an earthquake took place, it lacked but little of utterly wiping out the city. The city was also unfortunate when it was taken by siege by Alexander; but it overcame such misfortunes and restored itself both by means of the seamanship of its people, in which the Phoenicians in general have been superior to all peoples of all times, and by means of their dye-houses for purple; for the Tyrian purple has proved itself by far the most beautiful of all; and the shell-fish are caught near the coast; and the other things requisite for dyeing are easily got; and although the great number of dye-works makes the city unpleasant to live in, yet it makes the city rich through the superior skill of its inhabitants" (Strabo, Geography 16.2.23).
