I'm illustrating the Book of Psalms mainly under the light of the exegesis Saint Augustine did on them in his bright work “Enarrationes in Psalmos” (Expositions on the psalms). In any case I'm deepening into the psalms with all the help I can get as well from readings like "The art of biblical poetry" by Robert Alter, "Interpreting the psalms" by Mark D. Futato, "Praying the psalms" by Thomas Merton, "Biblical geography" by Denis Baly, "The Symbolism of the Biblical World: Ancient Near Eastern Iconography and the Book of Psalms" by Othmar Keel, "Dictionary of Biblical Imagery" by Ryken/Wilhoit/Longman, and all kind of guides through the Old Testament.
For this project I am using mainly the psalm's translations from "Biblia de Jerusalén" and "Nueva Biblia Española" in spanish. "New International Version", "NASB" in english.
