This character is introduced to the reader in the prologue by the name Sister Lucrezia, a nun who has recently passed away at Santa Vitella's Convent in August of 1528. During a routine cleansing of the body made necessary by a local plague outbreak, it is discovered that Sister Lucrezia has a tattoo on her body that extends from her shoulders to her sex. The reader expects from this that this character will not be an ordinary woman, but someone who has lived an extraordinary life. The reader will not be disappointed.
