Joseph Smith began translating the papyri in early July 1835, with Oliver Cowdery and William W. Phelps serving as his scribes. The current published text of the Book of Abraham, and probably more, seems to have been translated by the end of July 1835; the Book of Abraham appears to have been longer than the current text. In August 1835, Joseph Smith left Kirtland to visit the Saints in Michigan, and no translation was done during the trip. Revelation pertaining to the Book of Abraham was not known to have been received again until 1 October 1835. Translation continued intermittently through 25 November 1835, but Joseph then set aside the papyri to study Hebrew, finish and dedicate the Kirtland Temple, and, later, deal with troubles in Missouri. Joseph revised the translation preparatory to its publication in 1842, but other than that, no evidence has survived that he worked on the translation of the existing Book of Abraham after 1835. Unfortunately, Joseph was extremely busy and consequently somewhat haphazard in his record keeping, so we cannot be certain.
