Translation to latine and Late antiquity cursive

[AMELIANVS]

I guess something like paryrus rolls From Egypt or syria might possibly still exist.It is not a problem to find text in other forms but handwriting is harder to find from this era.I only find earlier and also this text dated to 5th century and later adorned with image of Heraclius with family.So I got something for Greek part at least or I can use mozaic works from those centuries-not really a handwritten letters but better than nothing.
