Geronimo Stilton is a mouse on a mission.
The Arabs endeavoured to induce Geronimo to renounce Christianity, but as he steadfastly refused to do so he was condemned to death.
And the algebraists or arithmeticians of the 16th century, such as Luca Pacioli (Lucas de Borgo), Geronimo or Girolamo Cardano (1501-1576), and Niccola Tartaglia (1506-1559), had used geometrical constructions to throw light on the solution of particular equations.
In one of the chapels is a tomb containing the bones of San Geronimo.
Haedo sets forth that a young Arab who had embraced Christianity and had been baptized with the name of Geronimo was captured by a Moorish corsair in 1569 and taken to Algiers.
