The final argument.

The final argument of kings. Louis XIV of France, recognized that force is the final argument, so he directed that his cannons carry the engraving ultima ratio regum (1650). As a result, this phrase usually signifies "war" or "the use of military weapons as a force". The phrase was adopted in the form of Ultima ratio regis for the same purpose which appears on cannon cast for Frederick the Great after 1742.

Ancient Greek mariners believed that the northern end of the world was an island called Thule, said to be six days' sailing distance from Britain.

The precise location of Thule is not known today, but ultima Thule, mentioned in Virgil's Georgics, survives as a useful expression for describing any place whose appearance gives one the feeling of standing at the end of the world. Maybe it was one of the Shetland Islands.

It may be of interest to note that the current list of Chemical Elements has an element named for this unknown "end of the world": thulium; symbol, Tm; atomic number, 69; which was discovered by Per Teodor Cleve in 1879.
