15. Siege of Lachish
This wall relief carving depicts the siege of Lachish, telling the story from the Assyrian point of view. The carving was created in c. 700 BC and was discovered in the 1850s in the ancient city of Nineveh, Assyria. The full original panel measured sixty-two feet in length and was nearly nine feet tall. The same events are recorded in the Bible in 2 Kings 18-19. The relief now resides in the British Museum.
(NOTE: If you click on the photo and enlarge it, the detail is really quite engaging. The defenders are throwing flaming torches, the attackers have battering rams, etc. In the lower right there are even depictions of victims being impaled.)
