title RIASSUNTO /title

Questo articolo tratta di un particolare tipo di strumenti ottici, gli orologi a rifrazione costruiti nel secolo XVI, collocandoli nel contesto delle conoscenze ottiche contemporanee. Verranno affrontate in primo luogo le propriet delle meridiane a rifrazione e la loro introduzione nel XVI secolo a opera del costruttore di strumenti tedesco Georg Hartmann. Si mostrer poi il modo in cui questi orologi a rifrazione venivano costruiti nel '500. Attraverso l'analisi delle note di Ettore Ausonio, il presente saggio sostiene che la procedura utilizzata dai disegnatori di strumenti del XVI secolo per la realizzazione di orologi a rifrazione si fondava sulle conoscenze della rifrazione contemporanee.
