In his book The True Story of the Rosicrucians historian Tobias Churton brought to light new documents that prove the Fama was written by a group of Lutheran scholars at Tübingen in which Andreae took an active part. After one manuscript written in 1612, which was intended to be circulated privately escaped their control, the movement took a life in itself, prompting new theories and pure speculations such as those brought forward by Émile Dantinne (1884–1969) who theorised that the origins of the Rosicrucians might have had an Islamic connection. Rosenkreuz started his pilgrimage at the age of sixteen. This led him to Arabia, Egypt and Morocco, where he came into contact with sages of the East who revealed to him the "universal harmonic science". After learning Arabic philosophy in Jerusalem, he was led to Damcar. This place remains a mystery — it did not become Damascus, but is somewhere not too far from Jerusalem. Then he stopped briefly in Egypt. Soon afterwards, he embarked to Fes, a center of philosophical and occult studies, such as the alchemy of Abu-Abdallah, Gabir ben Hayan and Imam Jafar al Sadiq, the astrology and magic of Ali-ash-Shabramallishi, and the esoteric science of Abdarrahman ben Abdallah al Iskari. However, Dantinne states that Rosenkreuz may have found his secrets amongst the Brethren of Purity, a society of philosophers that had formed in Basra (Iraq) in the 10th century. Their doctrine had its source in the study of the ancient Greek philosophers, but it became more neo-Pythagorean. They adopted the Pythagorean tradition of envisioning objects and ideas in terms of their numeric aspects. Their theurgy and esoteric knowledge is expounded in an epistolary style in the Encyclopedia of the Brethren of Purity.
