This enumeration is based on a brief survey of the materials in the Index of Christian Art at Princeton Univ., Princeton, NJ, as well as tables at the end of van Woerden’s article, “The Iconography of the Sacrifice of Abraham,” p. 243f. I should note here that I have found several mistakes and omissions in van Woerden’s accounting, however. Other significant articles that analyze the Christian image of Abraham’s sacrifice include Graydon Snyder, Ante Pacem (Macon, GA: Mercer Univ. Press, 1985), pp. 51–52 and Elizabeth S. Malbon, The Iconography of the Sarcophagus of Junius Bassus (Princeton, NJ: Princeton Univ. Press, 1990), p. 44f.
