You can start simply from wikipedia:
"The Seal of Solomon (or Ring of Solomon; Arabic: Khātam Sulaymān) is the signet ring attributed to King Solomon in medieval Jewish tradition and in Islamic and Western occultism. It was often depicted in either a pentagram or hexagram shape; the latter also known as the Star of David in Jewish tradition.
This ring variously gave Solomon the power to command demons, jinn (genie), or to speak with animals. Due to the proverbial wisdom of Solomon, his signet ring, or its supposed design, it came to be seen as an amulet or talisman, or a symbol or character in medieval and Renaissance-era magic, occultism, and alchemy."
I want to draw your attention to the words "magic, medieval, occultism, alchemy, speaki to animals & command demons". I believe this is directly linkd to the witch craft and the occultism stuff those weirdos do.
The rest is in here: https://en.wikipedia.org/wiki/Seal_of_Solomon
There are links and they even talk about King Solomon's sword, if you want to go that far into this rabbit hole.
They are selling plenty of books about it as well, i believe some are manuals for witch craft, you can find on amazon or ebay. I bet you can also find they in your local bookstore or library if interested. As for the "seals" themselves, they are selling them like candy on the net. You can check that out if you want and see who is selling and what they are. I believe each seal as it's own "powers", some are for protection, while others are to harm, or do good, while there are some related to money and stuff like that….. so happy digging anon.
