What does this mean?AR MA REGVM LEX EST?

Question

The order may not be correct. It is on a ring I found metal detecting.

Answer 1

The correct spelling is "ARMA REGUM LEX EST" (U=V). It's Latin and means "Weapons are (a) king's law."

Answer 2

All I can tell you for sure is that it is a latin expression of some kind.
LEX EST means "is (the) law". REGUM means "of the Kingdom"/"of the land". Until here, everything is certain and clear.
AR and MA do not mean anything I know of in Latin. They may not be the entire words. Provided that ARMA would form a single word..it could mean "arm" or "weapon".
Risking a full translation i would go for "The King's arm (in the sense of will, or representation, I guess) is Law".
Sounds like something a British officer or official would have engraved on his ring, if you ask me. Where did you find that ring, geographically speaking, if I may ask?
Good luck with finding out everything you want to know!

Answer 3

Arma regum lex est can be translated as follows:
War is the law of tyrants (or)
Military force is the law of kings

Answer 4

This means, in Latin, "The law is the arm of the realm (or king)". This phrase comes from a lawyers ring. As early as the 14th century, when a man finished his education and apprentice time and was ready to work for himself, he would be given a ring such as the one found. There is one in a museum from centuries ago. It is reproduced by the lost wax method in silver and gold and still popular as a law school graduation gift or bar exam passing gift. I got one when I graduated from law school in 1997.

Answer 5

I know a merchant who sells it as "Lex est arma regum" and defines it as "Law is the tool of the monarch" or "Law is the arm of the realm."

Answer 6

It seems like something that would be either Latin or Greek. Is the writing on the inside of the ring or the outside?

edit: Ah, Helga seems to have it.

Answer 7
