"Abulafia himself wrote an autobiographical account of this conversion attempt [of Pope Nicholas III] in his Sefer HaEdot (Book of Testimonies). In this account, he calls himself Raziel, an anonym that he frequently used, this being the name of the angel who taught the mysteries to Adam. Raziel () has a numerical value of 248, this being the same as that of Abulafia's first name, Abraham (). As Abulafia himself indicates, this relationship is more than a simple gematria, but it is a mishkal (balance), since both the numerical value and the number of letters in both names are equal."
