Large deltas spotted at Pompeii?

Hey folks,

I've been running around the EU for the past couple of weeks. While visiting Pompeii I spotted two large deltas on site! ?
I haven't had a chance to look into them yet as I've just arrived home (after 22hrs of travel)
Thinking of you guys I took a photo (they were behind bars hence one angle).
Let me know if you have anything on them (Haven't had a chance to look yet).

Joe
