"Golden Swords of the Early Nomads of Eurasia: A New Classification and Chronology (https://www.mdpi.com/2076-0752/13/2/48)", by Denis Topal, from Arts (2024).
Quite dense with stylistic data and arguments, but some lovely pictures of beautiful gold-decorated swords and scabbards.
Thanks for flagging that up Duncan. Great pictures and lots of things to chew on.
Some stunning stuff :)
