G.T. Waters asks:

Do you by any chance know who were the first people to make use of lighthouses and the symbolism of lighthouses in antiquity?

Genuinely no idea.  I would guess that the concept of a lighthouse – a tall coastal structure (or even just a signal fire on a hilltop) that provides light for ships to navigate by – probably starts not long after the earliest permanent maritime harbours, which means it almost certainly goes back well into the Early Bronze Age (3rd millennium BC, give or take), and maybe even the Neolithic.  As for where, I’d say Syria or Israel-Palestine is a good bet, but the Persian Gulf would also make sense.  Maybe even southeast Asia, but I don’t know anything about the archaeology of that region.
