Imperial Itallic D Mainz Helmet

[trottlesnot]

Thank you very much Trottlesnot for these important informations!!!
Perhaps, do you know the archaeological context (place, chronology and other informations) within the hoard was found?

best regards

Archaeological context is a bit unclear.

The official story is that it was found in a  heap of sand coming from construction work on the A4 high way near Leiden, where the highway crosses the Rhine, not too far from the fortress of Matilo. That is was found in sand is probably an indication the helmet (parts) is coming from the Rhine bed.  

However, quite a few people are a bit sceptical about this story.
