Helmet with laurel wreath from Aquileia-IT

[S. Marcer]

Hello everybody,
Looking the section of the website roma-victrix.com dedicated to the dona militaria I'd come across at this representation of roman helmet with laurel wreath from Aquileia (N-E of Italy), likely as part of funeral monument.

I would like to ask if anyone has more information about this monument, the chronology, and about the type of helmet represented ….

Thank you in advance for any information

Seems a cavalry helmet, often depicted with such wreaths (laurel or oak).
