Browne's account of the twelve months he spent in Persia in 1887–8, travelling from Tabríz to Ṭeherán, Iṣfahán, Shíráz, Yezd and Kirmán. Fluent in Persian, he sought out mystics, philosophers, dervishes and the persecuted Bábís, and set down their conversation at length: one of the classic books of travel, and a portrait of Persian thought and belief from the inside.
