Frederick Holweck, writing in the "Catholic Encyclopædia" says definite in its rejection of this argument: "The feast was certainly not introduced by Pope Gelasius to suppress the excesses of the Lupercalia," (referencing J.P. Migne, "Missale Gothicum", 691) The "1911 Encyclopædia Britannica" agrees: the association with Gelasius "has led some to suppose that it was ordained by Pope Gelasius I in 492 as a counter-attraction to the pagan Lupercalia; but for this there is no warrant." Since the two festivals are both concerned with the ritual purification of women, not all historians are convinced that the connection is purely coincidental. Gelasius certainly did write a treatise against Lupercalia, and this still exists.
