Athanasius Kircher Correspondence (AKC)


The publication of Kircher's Correspondence is the primary goal of the project. Our first aim is transcribing all the letters within the 14 codices preserved in the Historical Archives of the Pontifical Gregorian University; letters kept in other institutions will be added too. Each letter will be transcribed, commented and annotated with the help of GATE contributors. Annotation allows to univocally identify entities cited within the texts, such as names, places, works and so on; entities will have a dedicated page where users can acquire information about them.

The Athanasius Kircher Correspondence is a huge corpus of letters written and received by Athanasius Kircher during his whole life. From this page you can browse the correspondence through indexes and other research tools.

If you want to collaborate to the Athanasius Kircher Correspondence transcription project, you should ask for an account by using this form.

Thanks to the collaboration with the Early Modern Letters Online (EMLO) project, it's also possible to search directly on GATE some of the metadata of the whole correspondence (2,739 letters) recorded in EMLO. Read more at this page.


You can browse Years, Names and Places indexes of the Athanasius Kircher correspondence. Currently, these indexes include letters metadata only, so they don't list, e.g., cited names or cited works. If you want to perform a full-text search, you should use the search bar within this page.
By clicking on , you can expand the main index and sub-indexes of your interest; if you find a grey , it means no letters have been uploaded so far in that sub-index; by clicking on the index name, you will instead be redirect to that index special page, where you can find detailed information about how the entries have been structured.
