Tallay Ornan, “The Dayan Collection,” Israel Museum Journal 2 (1983), pp. 14–16, 18 n. 63. Ornan notes that a similar rosette diadem is seen on a female bust now in the collection of Mr. and Mrs. A. Spaer of Jerusalem. Because the Spaer bust appears to have been purchased from the same source as the bust in the Dayan Collection, the two busts may originally have formed a pair and should perhaps be identified as an Ammonite king and queen.
