Tar-Ardamin becomes King of Númenor
Meaning: The Pillar of Earth
Event Type: Political
Age: 2nd Age - Rings
He assumed the sceptre on the death of Tar-Calmacil. His name in Adûnaic was Ar-Abattârik.
In 'Unfinished Tales' Christopher Tolkien writes:
"When editing the Akallabêth I changed the actual reading "And the twentieth king took the sceptre of his fathers, and he ascended the throne in the name of Adûnakhôr" to "And the nineteenth king..." (The Silmarillion p. 267), and similarly "four and twenty" to "three and twenty" (ibid. p. 270). At that time I had not observed that in "the Line of Elros" the ruler following Tar-Calmacil was not Ar-Adûnakhôr but Tar-Ardamin; but it now seems perfectly clear, from the fact alone that Tar-Ardamin's death-date is here given as 2899, that he was omitted in error from the list in The Lord of the Rings."
