Its preface stated: Mediam autem inter has latinam beati Hieronymi translationem velut inter Synagogam et Orientalem Ecclesiam posuimus: tanque duos hinc et inde latrones medium autem Iesum hoc est Romanam sive latinam Ecclesiam collocantes (Prolog. II).
Here is a translation following Basil Hall (in Greenslade, E.L. ed., The Cambridge History of the Bible):
We have placed the Latin translation of blessed Jerome as though between the Synagogue and the Eastern Church, siting them like the two thieves, one on each side, and Jesus, that is the Roman or Latin Church, between them.This sardonic statement appears at the start of the bible, a masterpiece of typography and Catholic scholarship, which was printed between 1514 and 1517 in Alcalá de Henares (Complutum in Latin). The Complutensian Bible is available as a PDF from Archive.org.
