 Other Versions of the Legendarium
In the Tale of Years, it said in 2251 "Tar-Atanamir takes the Sceptre", however, Atanamir died in S.A. 2221. The year 2221 is itself an emendation of 2251, and the former (2221) appears in the later tables, while the latter (2251) in the earlier tables: therefore 2251 (properly 2221) should have read "Death of Tar-Atanamir. Tar-Ancalimon takes the sceptre".
