This miniature illustrates a siege in which Nebuchadnezzar captured Jerusalem and, on the plain of Jericho, the escaping King Sedecias of Judah. At the bottom left sits the enthroned Nebuchadnezzar, flanked by guards in thirteenth-century armour; he directs the blinding of Sedecias and the killing of his sons (4 Kings 25:1–7).
Referenced in p33, The Moors - The Islamic West - 7th-15th Centuries AD by David Nicolle:
The Beatus de Liebana was made around AD 1220, and although it is a Spanish rather than Mozarab manuscript, the artist has modelled several military figures upon Muslim Andalusian troops. Here the army and guards of King Nebuchadnezzar have some distinctive features, such as large white shields with three tassels - a common Moorish fashion. They also have quilted soft armour worn over mail hauberks.
