Pseudo-Plutarch is the conventional name given to the actual, but unknown, authors of a number of pseudepigrapha (falsely attributed works) attributed to Plutarch but now known to have not been written by him.
D. Blank has recently shown that Pro Nobilitate was written by Arnoul Le Ferron (Arnoldus Ferronus) and first published in 1556.
[4] One pseudepigraphal philosophical work, De Fato (On Fate; included in editions of Plutarch's Moralia), is thought to be a 2nd-century Middle Platonic work.
Stromateis (Στρωματεῖς, "Patchwork"), an important source for pre-Socratic philosophy, is also falsely ascribed to Plutarch.
[6] Some works ascribed to Plutarch are likely of medieval origin, such as the "Letter to Trajan".
