I was looking for archeological finds of lamellar from early medieval Scandinavia, and came across and article mentioning lamellae found in 2 separate burial mounds in Snäckgärde, near Visby, Gotland. All it said was that they were found by a priest named Nils Johan Ekdahl in the 19th century, and were lost some time in between then and now. I’m just wondering if these finds were lost, how does anyone know about them in the first place, and are there surviving written descriptions of them or drawings?
The article can be found here: https://sagy.vikingove.cz/lamellar-armours-of-the-viking-age/
I am following the same trail of breadcrumbs you are. And the surviving written descriptions by Nils Johan Ekdahl is what we're both attempting to find. The term used in the article we're both here from though mentions scales of armour were found. Grave two says small pieces of armour, then grave four changes that to scales of the same armour, indicating the small pieces were scales. The probability it is banded armour and not lamellar is high though.
