Calouste Gulbenkian (1869–1955), the famous Portuguese collector, was a friend of René Lalique’s for fifty years, as well as a great connoisseur of the various activities of this versatile artist. Between 1899 and 1927 he acquired eighty extraordinary works of art directly from the artist. Today, these are conserved in an exclusive space inside the Calouste Gulbenkian Museum in Lisbon. This unrepeatable collection of jewelery, art objects, artistic glass, and drawings, being published for the first-time in a large format catalogue gives the reader a complete and exhaustive idea of the entire artistic activity of Lalique.
