BIBLE HISTORY DAILY: The Masada Siege. The Roman assault on Herod’s desert fortress (Robin Ngo). This was originally posted in 2014, but I seem to have missed it then. To access the BAR article that it introduces, you need a paid personal or institutional subscription.
For past posts on the siege of Masada, the archaeology of the site, and related matters, see here and links (cf. here and here).
