This piece of artwork is composed of two pieces of agate dating back from Roman times, which form the bowl and the base. Around the year 1063, Lady Urraca incorporated a rich decoration of gold, filigree and precious stones into these pieces, thus giving the Chalice its current form.
Lady Urraca, daughter of the monarchs Fernando I and Sancha, was named ‘Domina del Infantado’ of Leon and later Lady of Zamora.
Media interest regarding this work awakened motivated by the publication of a research study (“The Kings of the Grail”, ed. Reino de Cordelia, Madrid 2014), carried out by the Doctors Margarita Torres Sevilla and José Miguel Ortega del Río.
According to the aforementioned historical investigation the original Roman bowl that was decorated to form this chalice, had been venerated since the fourth century BC as the cup used by Jesus Christ during the Last Supper, and also known as the Holy Grail.
Its artistic wealth is undeniable and its decoration is composed of gold, gilded silver, precious stones such as amethyst and emeralds, pearls and a human face made of glassy paste that has been considered a Roman cameo. In the knot we see green enamels, pearl cabochons, sapphires and emeralds. All this set with ornamented gold filigree topped by leaves and stems. In the lower part of the tiller or knot, there is an inscription made with a thin gold cord that reads: “IN NOMINE D (OMI) NOR VRRACCA FREDINA (N) DI” That can be translated as “In the name of the Lord, Urraca of Fernando’s”.
