 Among the incunables, dated back from the 15th century, stand out "De Claris mulieribus" (1497) by Giacomo Filippo Foresti and "De re militari" by Roberto Valturio.The collection of illuminated manuscripts, coming from different cultural and linguistic European boundaries, includes the "Regalis Historia" by Frate Leonardo and "De Civitate Dei" by Saint Augustine.The first stable theatre in Rimini is documented since 1681, when the city council decided on the transformation of the Arengo's main hall into a large theatre hall, hosting shows of amateur dramatics companies and the young Carlo Goldoni, who was studying philosophy in the city at that time.
