Coeck was painter to Charles V, and to his sister, Mary of Austria, Queen of Hungary (born in Brussels in 1503), to whom Charles V gave the government of the Low Countries. In her the arts and sciences found as enthusiastic a patron as they had in her aunt Margaret of Austria. Just as the latter had had her favourite painters in van Orley and Jean Mostaert, so she chose Peter Coeck for hers.

Coeck achieved great fame in the remarkable triumphal arches which he designed for the joyous entrance of Philip II into Antwerp. In 1527, he was made master of the Guild of St. Luke. Thierry de Moelenere intrusted him with the decoration of his rich house in Antwerp, in which he displayed his knowledge as architect, painter and sculptor. Some of the caryatides from this house are now preserved in the Steen Museum. A superb mantelpiece with three tiers of subjects carved by his hand is in the Town Hall of Antwerp.

Coeck also executed a window for the Church of Notre Dame in Antwerp.

Among his pupils were the painters, Pierre Clays, Gilles de la Hee, Nicholas van Nieucasteel, surnamed Nicholas Lucidel, and Pierre Breugel the Elder (who married his daughter).

Lambert Lombard (1506–66), went to Italy in 1537. He returned to Liège in 1539. He was a painter, and more particularly an architect. He set up a school of painting and engraving, the first of its kind there. Three of his pupils brought great honour to his school: these were Francis Floris, called the “Flemish Raphael,” William Key and Hubert Goltzius. He worked very little himself beyond designs for engravers, and more often for paintings on glass. He was rich enough to indulge his taste for objects of antiquity. It was at this date that the study of numismatics came into existence in Belgium, and learned men took delight in setting up a cabinet of medals and coins: among the wealthy it became even a mania that was carried to extremes. Lombard’s collection, the beauty of which was praised by all his contemporaries, was composed of medals, coins, carvings, and other objects of high antiquity.

Hubert (or Hugo) Goltius (or Goltz), was a painter, engraver, numismatologist and historian. He was born at Venlo in 1526 and died in 1583. He studied under Lambert Lombard and was also influenced by Erasmus’ friend, van Watervliet, who guided him in his classic studies, Greek and Roman antiquities, etc.

Goltius visited all the great towns in Belgium, Holland, Germany, France and Italy, in order to examine the cabinets of collectors for material for his book on coins. His itinerary reveals an astonishing number of collectors of coins and medals.

Goltius made the decorations in Antwerp for the fêtes of the Golden Fleece. He was also appointed historian to Philip II.

A marriage coffer of leather, designed by him, represented the King of Spain and Margaret of Austria standing beside the Fountain of Love.

The craze for medals, coins and curios during the sixteenth century was widespread. We have seen that the Regent had a coffer full of corals and various trifles. To meet the demand for housing curios, the cabinet was developed. This was usually a double chest, the upper one smaller than the other. Both closed with doors and contained drawers and shelves.
