The Astra Papers are scholarly peer-reviewed research materials on the history of astrological practices and techniques, published under the umbrella of the Astra Project. They offer short or very focused studies on textual, artistic, or material historical astrological sources. These include analyses of manuscripts or printed texts, technical studies on astrological materials, editions of astrological documents, and other works on pre-modern practices and techniques of astrology. The Astra Papers are open-content and are available for download below.

The Astra Project is an international, multidisciplinary project for the study of the history of western astrological doctrines, techniques, and practices from antiquity to the early modern period. The project is housed at CIUHCT, University of Lisbon, in partnership with The Warburg Institute, University of London and the IKGF, University Erlangen-Nuremberg.
