The 1901 Jewish Encyclopedia
A tomb twenty feet high and twenty-four feet square, which late tradition points out as the resting-place of Absalom. It is situated in the eastern part of the valley of Kidron, to the east of Jerusalem. In all probability it is the tomb of Alexander Jannæus (Conder, in Hastings' "Dict. Bible," article "Jerusalem," p. 597). It existed in the days of Josephus ("Ant." 7:10, § 3). See illustrations on pp. 133,134.
