This article combines an analysis of Francesco Algarotti‘s influential Newtonianismo per le Dame (1737) with an examination of the author‘s courtly practices. Algarotti is examined as a translator from a dual spatial and historical perspective: first, his mediation between knowledge spaces is addressed. His introduction of Newton‘s physics, divided into six dialogues, is a free translation of Newton‘s Opticks. It translates the scientific language into a form suitable for a courtly, noble audience. The acquisition of knowledge is imagined through cabinets, temples, and theaters spread across various rooms. Secondly, the article examines the princely court as a space of translation. In this context, Algarotti acted as a translator in his courtly practices. He developed concepts of linguistic and cultural translation for this space (‚scientific conversation‘), which he also used strategically to further his own ambitions. Thus, he staged himself as a translator and mediator of texts and cultures, for whom spatial thinking, movement in space, and spatial metaphors played a central role.
