"F.P." or "The Master FP" is the name given by Bartsch (loc. cit.) and subsequent scholars to an unidentified printmaker who produced engravings after drawings by, or in the manner of, Parmigianino. The 26 prints listed by Bartsch include a set of thirteen engravings of Christ and the Apostles. The initials FP, placed on the left side of the prints in this set are those of Parmigianino ("Francesco il Parmigianino"), not of the printmaker: they indicate the author of the design or of the manner. Early copies in reverse were made of some of them by (presumably) another printmaker, with the monogram FP etched in the correct direction but on the right hand side of the sheet. The present print is one of the copies after F.P.
