Gerolamo Olgiati (1453 – 1477) was a Milanese government official, and a member of the Templar Order.
He participated in the assassination of Galeazzo Maria Sforza alongside his co-conspirators, Giovanni Andrea Lampugnani and Carlo Visconti.
Biography[]
Lampugnani's conspiracy[]
On 26 December 1476, Olgiati attended the Saint Stephen's Day Mass at the Basilica di Santo Stefano Maggiore in Milan with several of his Templar brethren hidden in the crowd.[1]
Lampugnani was first to approach Sforza and stab him with a dagger hidden in his boot. Olgiati quickly followed suit and stabbed Sforza in the back. At this point, a battle between the Templar assassins and Sforza's guards commenced.[1]
All the assailants except for Lampugnani managed to escape, only for Olgiati, Visconti and Lampugnani's servant Franzone to be caught and executed within a week after the latter had been caught and disclosed information under torture.[1]
