I actually recognise the glass, it is Phoenician, from Malta.
(I've been after one of these for a long time!)
But what I
seem to be able to read on the base is Mtarfa. Also Maltese. I'm confused.
Welcome!
Can you try taking another photo of the mark on the base, but rub a little talcum powder over the marks first, to help make them clearer?
I cannot speak any language other than english, so you are already far better than I am.
(I've been peering again, perhaps the bit I think says "Mtarfa" says Malta? and there is something above that?)
The talcum powder trick should help!
