I want to know the answer to the following question:
What type of sacrifices were required to expiate the minor prodigies ?
All the background I'm provided with is that "The discovery of an androgynous four-year-old child was expiated by its drowning and the holy procession of 27 virgins to the temple of Juno Regina, singing a hymn to avert disaster: a lightning strike during the hymn rehearsals required further expiation.". Is that enough to answer the question?
