These two families of glass may be traced, often side by side, in much later works—in the pictures of the Flemish and Dutch schools of the seventeenth century. In the paintings of the former school, however, a clear white glass soon becomes prevalent even in humble surroundings. In the _cabaret_ scenes of Teniers, the peasant drinks his beer from a tall hexagonal glass of thick whitish metal. The wine is kept in spherical long-necked flasks—a very old type which we have often met with in our history—a plug of rolled paper taking the place of a cork; it is drunk from wide-mouthed conical glasses of thin white metal. Similar glasses appear indeed in the pictures of the Dutch painters (as in more than one painting by Metsu and De Hooghe in the National Gallery). But in Holland, in the seventeenth century, the dark green or almost black prunted goblets of _roemer_ type were apparently held in even greater estimation. In the famous terrace scene of Jan Steen (National Gallery, No. 1421), the wine, which is kept in a large pear-shaped glass vessel with a stopper of wood, is drunk from a small graceful _roemer_. In J. van de Velde’s still-life in the same collection (No. 1255) we see again a magnificent _roemer_, of very dark glass, with prunted stem and threaded foot, half filled with Rhenish wine.[181] But if we turn again to the Flemish painters of this later time, we find that when in rich interiors they introduce specimens of glass among other _objets de vertu_, this glass is always of a Venetian type. There is one such painter, a follower of Jan Brueghel apparently, who loves to introduce among a wealth of plate and jewellery, piled on tables and shelves and even on the floor, the most elaborate specimens of the fine _cristallo_ of Venice, proving in what esteem this glass was then held in the Spanish Netherlands. I might give many further examples, but enough has been said to show that as in the case of porcelain, of fayence and of plate, so for the history of glass, a mine of information may be found in the _genre_ and other pictures of the Netherlandish school.
