Divino Afflante Spiritu §11

¹¹ There is no one who cannot easily perceive that the conditions of biblical studies and their subsidiary sciences have greatly changed within the last fifty years. For, apart from anything else, when Our Predecessor published the Encyclical Letter Providentissimus Deus , hardly a single place in Palestine had begun to be explored by means of relevant excavations. Now, however, this kind of investigation is much more frequent and, since more precise methods and technical skill have been developed in the course of actual experience, it gives us information at once more abundant and more accurate. How much light has been derived from these explorations for the more correct and fuller understanding of the Sacred Books all experts know, as well as all those who devote themselves to these studies. The value of these excavations is enhanced by the discovery from time to time of written documents, which help much towards the knowledge of the languages, letters, events, customs, and forms of worship of most ancient times. And of no less importance is papyri which have contributed so much to the knowledge of the discovery and investigation, so frequent in our times, of letters and institutions, both public and private, especially of the time of Our Savior.
