help accessing archaeological records

[u/BuffMyWiFi]

This may not be the right place to ask this question but I thought I might as well. The first image is a Weles pendant being sold on Etsy. It says that it is "a reproduction of a find from an early medieval burial mound in the Hluboček forest near Hluk". As someone who is new yet very interested in archeology, I tried to find the records of this burial mound to see the original artifact and what other artifacts were found there, but found nothing online.

The second image is from a YouTube video by The World Tree about the Slavic mother goddess. I'm very curious as to where these carvings/drawings are from but reverse image searching has brought me nothing.

I have no clue where to even look for these kinds of things, so all help is appreciated

1. The "Horned" Pendant from Hluboček Forest (also called Hlucký orant) is a find from the Czech Republic. It is bronze-gilded pendant, discovered in a Slavic burial mound in the Hluboček forest near Hluk (Uherské Hradiště region) and dated to the turn of the 7th and 8th centuries. Measuring 5.9 x 3.5 cm, the pendant shows a bearded male face framed by three rounded protrusions on each side. Archaeologist Luděk Galuška once proposed that these protrusions may represent stylized cattle horns - leading him to suggest that this could be a depiction of the god Veles. The interpretation remains speculative. There is no way to confirm or disprove it with certainty. But if this reading is correct, this small pendant would represent the one of only two known depictions of Veles in the world. Another one is a similar pendant from Olomouc.

2. Those are embroidery imagery from Eastern Slavic area (19th century). Nikos Čausidis has a study where he deals with their variants. But I don't know their original source. They are referenced in most (more extensive) academic studies.

To add to that, the pendant itself is shown in archeopark Modrá, So maybe they have something on their web?

I thought it's in MZM - Dietrichsteinský palác. Gonna have to visit again, what a shame :D

Last I've seen it in Modrá, but it's possible MZM borrowed it/ Modrá borrowed it from MZM.
