Astrolabe, by Giovanni Domenico Fecioli, Trento or Bologna, 1558 (Inv. 50257)
The commission
This instrument is unusual in bearing the names of both the maker, who came from Trento in Italy, and the original commissioner, who lived in Bologna. We are told that 'Giulio Cesare Luchino of Bologna supervised the construction of this astrolabe for himself according to the Tabulæ Bergenses in the year 1558'.
