More recent attributions of authorship range from "the Arabic version is anonymous" to reiterations of the old claim that the author is "the celebrated astronomer and mathematician Abu l-Qasim Maslama b. Ahmad Al-Majriti". One recent study in "Studia Islamica" suggests that the authorship of this work should be attributed to Maslama b. Qasim al-Qurtubi (died 353/964), who according to Ibn al-Faradi was "a man of charms and talismans". If this suggestion is correct it would place the work in the context of Andalusian sufism and batinism.
