Arvegil lived for one hundred and ninety years, longer than any of his descendants until Aragorn, as is noted in the Appendices to The Lord of the Rings. By the standards of his own ancestors, though, this was an early death. Of all the northern Kings before Arvegil - excepting those slain in battle - only two had lived less than two hundred years: his father Argeleb II and his grandfather Araphor.
Arvegil ruled Arthedain for seventy-three years, and was succeeded by his son, who ruled as Arveleg II.
The date of Arvegil's birth appears only in The History of Middle-earth volume 12, The Peoples of Middle-earth. It cannot therefore be considered completely reliable.
The Ar- element of Arvegil's name denotes his claim to royal title over the old land of Arnor, but -vegil is uncertain. Some sources suggest that it may be a mutated form of the word megil, 'sword'.
