This work was first published in 1871. It contains a map. Continuing the history to 1870, Badger has translated from Arabic texts and included a lengthy introduction and analysis. Badger writes in the Introduction: This work embraces the annals of ‘Oman from the rise of Islam down to a very recent period, and is, I believe, unique in the continuity and fullness of its narrative. The native records from which the earlier portions are compiled, if they ever came within their reach, have never, to my knowledge, been utilized by foreign authors either in the East or West.
