The exhibition 'Segnare le ore. Gli orologi del Quirinale", in the Palazzina Gregoriana of the Quirinale Palace. The aim of the exhibition is to highlight and make known to both the public and specialists the extraordinary collection of clocks housed in the Palazzo del Quirinale, which are in perfect working order thanks to the maintenance of the Palazzo's in-house workshop and the care of the cabinet-makers who have, among other things, restored precious cases, such as the one made before 1692 by the Florentine Grand Ducal Manufactory for Cosimo III dei Medici, which is on public display for the first time.
Forty-eight of the more than two hundred exhibits are on display, most of them of French manufacture, belonging to a chronological span between the end of the 17th century and the end of the 19th century and in particular related to the Louis XV style, significant interpreters of a "lightness of time" typical of the period. Accompanying the exhibition is a series of printed engravings from the Encyclopédie volume by Diderot and D'Alembert on watchmaking mechanisms. The exhibition is curated by Marco Lattanzi, art historian at the Area Tutela e Valorizzazione del Patrimonio Artistico del Segretariato Generale della Presidenza della Repubblica. The conception and design of the layout is by Michelangelo Lupo, the exhibition catalogue is published by De Luca Editori d'Arte.
