Giuseppe Ceri (1839-1925), Quirico Filopanti (1812-1894)

The periodical Ehi! cha’l scusa... of 1844 imagined in this cloister the engineer Giuseppe Ceri who, on a night in which the ‘dull silver moon illuminates the walls of the Certosa’, is surrounded by bats that ‘are gradually closing in on his top hat’.
In Aneddoti bolognesi (1929) the protagonist is Quirico Filopanti: in search of will-o’-the-wisps, he is tricked by the caretaker Marcellino Sibaud, who ‘began to move around in various directions’ with a lantern.
