Jami' al-tawarikh
John Staples Harriott (1780–1839) was a British army officer stationed in India, in the service of the East India Company. He came to acquire the "Jami' al-tawarikh" in its original manuscript. In his studies of the Roma people, he made an identification with a legend of Bahram Gur and the Luri to support a Romani presence in Sasanid Persia, now considered to be an unjustified and uncritical deduction that has persisted.
