Mark Jenkins’ article on the “Treasures From the Royal Tombs of Ur” exhibition (“The Ur-Text of History,” 10/29) was scholarly and informative. One mixed metaphor jarred, however. “Ur owes its metaphorical prominence—reflected in terms like ‘Ur-text’—not to archaeology but to the Bible…” The prefix “ur-” in “ur-text” has nothing to do with Ur of the Chaldees but is a German root expressing origin or great antiquity, as in Ursache (“cause”), Ursprung (“source”), or Urvater (“ancestor”). Jenkins should have paid less attention to “ur-text” and more to context.
