The horseman is said to be a deity. Is that a 'xyston' length weapon he is using?

Nice find and a detailed write up too

The six legged horse is a bit of a giveaway.

Nice. Bearing in mind that the find is probably from the 3rd century AD, and it is suggested that the deceased may have been a Roman army veteran, the horseman reminds me of portrayals of Roman contarii.

I did at first think it was well on the way to being Sleipnir, but I think the extras may be tracery rather than legs.

maybe, but multilegged animals as shamans' steeds are a feature of steppe religion, being found in Scythian contexts.  And there is this piece of Hungarian folklore

The táltos steed would typically appear at first to the protagonist (usually a peasant's son, adventuring prince, or a youngest son) disguised as an old and ugly jade. If it is treated well, it would ask the hero to feed it hot cinders, whereupon its transform into a steed with golden coat, golden saddles and five or six legs. In this form it could fly with the protagonist on its back; its speed is mandatorily described as "faster than a bird", "faster than wind", and finally "faster than thought".
