The Cathedral of Sigüenza (Guadalajara) owns sixteen Flemish tapestries, that are very valuable, scarcely known and until now unstudied. In eight of them the "History of Romulus and Remus" is represented. In the other eight, that the author calls "Allegories of Palas Atenea", are depicted the virtues that the mythology conferred to this goddess. All of them were woven in the 17th Century in Brussels, in the workshops of the Le Clerc and the Eggermans. Both factories worked both series sharing the work. These beautiful tapestries were donated by D. Andrés Bravo of Salamanca, bishop of the diocese from 1662 to 1668, and they are mentioned for the first time in the Acts of the Chapter of the Cathedral in the year 1664 as a valuable present of the above mentioned bishop.
