Abstract

Little is known on the published works of Ruggiero Giuseppe Boscovich that refer to a tradition of applied antique knowledge this distinguished philosopher of nature from Dubrovnik has implemented in his scientific and engineering work. The study by Boscovich and his colleagues Thomas Le Seur and François Jacquier in 1742 indicates that when defining the form and structure, the builders of St. Peter Basilica Dome in the Vatican, among whom was Michelangelo Buonarroti, complied with the antique tradition based on geometric implementation of the system of continuous division and musical analogy, but also on their synthesis within the so-called Plato's geometrical number. Regarding this, we aim to show that the ancient- and Byzantine-Renaissance teachings continued development and were used in a technical manner after the XVI century. Among XVIII century prominent scholars who continued application of ancient knowledge, a special place is dedicated to Ruggiero Boscovich.

Keywords: Ruggiero Giuseppe Boscovich, Plato's geometrical number, golden ratio, St. Peter's Basilica, musical analogy
