This confusion of identity arises from Giovanni, who wrote the dedication for Vittoria, in her only published book of music. In it he suggests that while his oldest daughter was being prepared to become a nun and trained in music, his younger daughter, Vittoria, overheard and took a liking to music. With this knowledge, some suggest that Vittoria and Raffaella are two different women. To support this assertion, many have written that it was almost impossible and highly unlikely that the same woman would publish two books of different music under two different names. In addition, it is said that while Vittoria entrusted the dedication of her works to her father, Raffaella took full responsibility of writing her own dedication, thus insinuating the stark personality differences as well.
