Browne was not a Baháʼí, but rather an Orientalist. His interest in the Bábí movement was piqued by a book by de Gobineau found while he was looking for materials on tasawwuf. The history "A Traveller's Narrative" was written by `Abdu'l-Bahá and translated by Browne, who added a large introduction and appendices. Browne was fascinated by the development of the written historical perspectives of the Baháʼís regarding successorship after the Báb including their idea of an independent dispensation of Bahá'u'lláh. These Baháʼí-authored works emphasized Bahá'u'lláh to a greater extent than the Báb and took a critical view against Subh-i-Azal, whom Arthur de Gobineau listed as the Báb's successor. Browne expressed sympathy for Subh-i-Azal and surprise at the route the religion had taken.
