Fernando Pessoa and Aleister Crowley: new discoveries and a new analysis of the documents in the Gerald Yorke Collection

The documents concerning the relationship between Fernando Pessoa and Aleister Crowley preserved in the Yorke Collection at the Warburg Institute (London) have been known for some time. However, recent new findings have prompted a new analysis of the dossier. The purpose of this article is to have a new look at the documents that were already known and introduce the documents that have been recently found. The analysis will also be based on a comparison with the related documents from the "Magick" collection, now part of Pessoa’s Archive at the Biblioteca Nacional de Portugal in Lisbon. Photographic images of the documents, together with a new edition of the texts, are also included.
