Some apology may seem necessary for presenting a life of Mahomet at the present day, when no new fact can be added to those already known concerning him. Many years since, during a residence in Madrid, the author projected a series of writings illustrative of the domination of the Arabs in Spain. These were to be introduced by a sketch of the life of the founder of the Islam faith, and the first mover of Arabian conquest. Most of the particulars for this were drawn from Spanish sources, and from Gagnier's translation of the Arabian historian Abulfeda, a copy of which the author found in the Jesuits' Library of the Convent of St. Isidro, at Madrid.
Not having followed out in its extent the literary plan devised, the manuscript life lay neglected among the author's papers until the year 1831, when he revised and enlarged it for the Family Library of Mr. John Murray. Circumstances prevented its publication at the time, and it again was thrown aside for years.
