ANYONE ANY IDEAS? -MEDIEVAL SWORD INSCRIPTION/INVOCATION

[Reventlov]

Based on comparison with other inscriptions, I think a plausible reading of the first side might be RCDNISRTNEDA. The two most relevant comparisons that I've found are swords from Oldenburg and Karlstad.

The Oldenburg sword belongs to the NED group, and also uses the sequence RC. This can be found in a several other inscriptions, in at least two cases as the first two letters.

The Karlstad sword is instead part of the SDX group, this sequence having been recently identified by scholars as sanctus dominus Christus. The sequence RT is used twice, immediately before IS, versus immediately after. The odd uncial variant of the letter T is used again here (not illustrated very clearly), and the cross of the sword is again type 2.

Both swords seem to have incomplete versions of the other's key sequence (SD vs. NE). I think the "inscription groups" that have been identified (NED, DIC, SDX) are not really distinct at all; there are many similarities and shared minor sequences like RT and RC, which probably also refer to certain standard phrases.

Both swords use the seemingly conjoined form of IS that is extremely close (or actually is?) a letter U/V. The crosses are also very elaborate and distinct; is there any chance that similar details are present in the crosses on your sword, Jasper?

Best,

Mark
