Inaugurating the series ‘Museum Treasures’ dedicated to a single piece or a small selection of works from the permanent collection, the museum publishes a study by Maria Helena Rocha-Pereira, the greatest Portuguese authority on Classical Studies, covering its 4th-century BC , Attic red-figure painted calyx-krater. The vase, considered the finest specimen of Greek classic ceramics in Portugal, was acquired by Calouste Gulbenkian at the important sale of T. Hope collection, through Christie’s, London, in 1917.
