Earlier today, while diving at one of the ancient shipwrecks in Vis, Croatia, I found another treasure. I discovered an ancient Greek jug. I reported the item to the Croatian Ministry of Culture and Media and it will be recovered by them in the near future.
Here is what the jug looks like
If you find any object of archaeological interest under water or on land, then report it to the relevant authorities. Do not move it off site. Leave it where you found it, unless there is a possibility someone may steal it.
This is actually my second ancient jug found in Vis. Here you can read about the one I found last year.
