Mrs Mendoni has confirmed that the letter I pointed out in a photo is indeed there, and probably a mason's mark dating the building. Press report here.
I'm going to stop using puns like "hold your horses" which just means to be patient, but which I realise is open to interpretation ... and try to be clear.
This sort of mark is not like seeing things in clouds, but is easy to spot if you're an archaeologist - and that's why I've been trying to explain the finds.
That's the easy part - doing the research and explaining the finds, and it is very easy for me to do from the photos being released without being on site. It doesn't need leaks if you're good at what you do, and can recognise something seen on many other buildings.
The hard work is what those on the site are doing - not just Dr Peristeri and architect Lefantzis, who get the credit, but every single person on the team including the too often overlooked technicians who are some of the most skilled in the world.
