1. Meridiana Monumentale / Monumental Sundial Marker
Meridiana Monumentale Concepita come 'ornamento matematico' del Museo Galileo, la meridiana θ stata costruita nel 2007 su disegno di Luise Schnabel e Filippo Camerota, col contributo di Ente Cassa di Risparmio di Firenze. Nel 2015 θ stata restaurata grazie al generoso sostegno di Officine Panerai. L'ombra del poliedro di vetro collocato in cima al grande gnomone di bronzo indica l'ora solare vera e la data. Le linee radiali di ottone sul selciato marcano le ore, mentre le linee trasversali di travertino segnano il percorso diurno del Sole in vari periodi dell'anno, indicando la data e il succedersi di mesi e stagioni. La meridiana segna il tempo solare vero che varia periodicamente rispetto al tempo medio indicato dall'orologio.
Monumental Sundial
Conceived as an attractive identifying marker for the Museo Galileo, this sundial was designed by Luise Schnabel and Filippo Camerota and built in 2007 with the contribution of Ente Cassa di Risparmio di Firenze.

Excerpt: "The monumental sundial was built in 2007 as a mathematical ornament for the Museo Galileo. Well known since antiquity, the sundial is a time-measuring instrument made up by a style casting a shadow on a quadrant. Its functioning is based on the observation of the styles shadow combined with the notion of the Sun as a time-keeper apparently revolving around the immobile Earth in a uniform daily motion."(Submitted on September 2, 2025, by Sean P.
