"Thanks are due to The Newman Press for permission to reproduce material from Thomas P. Scheck's previous translation of St. Jerome's Epistles 18A/B, which appears in the appendix of St. Jerome: Commentary on Isaiah, including St. Jerome's translation of Origen's Homilies 1-9 on Isaiah, Ancient Christian Writers 68 (New York and Mahwah, NJ: The Newman Press, 2015). Although Dr. Scheck has used a different Latin text for his new translation in the present volume, there is a high degree of overlap between the two texts and the two translations. The Newman Press has also kindly granted permission to reproduce some material from Dr. Scheck's introduction and endnotes in his previous volume"--Title page verso.
