The book, which covers a time span from 1921 to 1985, illustrates the glassworks' work in the field of lighting, from large to small scale, tracing an excursus through its most significant interventions. More than five hundred entries, accompanied by a considerable amount of mostly unpublished iconographic material, document an incessant activity made up of numerous projects of historical and cultural importance, including those in collaboration with Angiolo Mazzoni in the 1930s, the realisation of the Palazzo Grassi in Venice in 1951, Carlo Scarpa's large installation for Italia 61 in Turin, the Fulda theatre in Germany in 1978, etc. A careful selection of works recounts the transformation of Venini lamps, their form and material. With material from Venini's historical archive, most of it previously unpublished, it is also accompanied by a rich documentary apparatus, consisting of a substantial graphic corpus (catalogue drawings, preparatory drawings for the Blue Catalogue and the pages of the Red Catalogue), for a total of more than four hundred images that contribute to the narration of Venini's extraordinary history.
