Among the documents relating to glass, collected by the Baron Davillier, was the report of the commission of inquiry appointed by Philip II. at the time (about 1560) when it was proposed to glaze the many thousand windows of the Escurial. Samples were sent from the glass-works of Spain, Burgundy, Lorraine, and Normandy. The Norman glass was declared to be the purest. (Quoted by Gerspach, p. 304.) Footnote 176: These _canons_, I think, correspond to the Italian _canni_, the glass rods from which beads were made. We hear of these _canons_ being supplied to the _Pâternostriers_, who take the place in France of the _Suppialumi_ of Venice. Footnote 177: It seems to me, however, very doubtful whether flint-glass was at this time necessarily _glass of lead_. I return to the point in the chapter on English glass. Footnote 178: I use the term Bohemian, here as elsewhere, for brevity’s sake. The more correct expression would be—the frontier lands of Germany and Bohemia. This will be made clear in the following chapter. Footnote 179: So in the important collection of the Musée des Arts Décoratifs at Brussels, especially strong in examples of ‘winged’ beakers, little attempt is made to separate the Venetian from the home-made specimens. Footnote 180: Attributed to the painter known as ‘The Master of the Death of the Virgin.’ In other works of this painter, who was working during the first thirty or forty years of the sixteenth century, we find examples of _cristallo_ of large size and advanced technique. Footnote 181: I do not know why this essentially Teutonic form is described in the official catalogue as a ‘Venetian green glass goblet.’ Footnote 182: Riaño, _The Industrial Arts of Spain_. The little that we know, on the documentary side, of Spanish glass is derived for the most part from this work, one of the South Kensington handbooks. This may be supplemented by the information collected shortly before his death by the Baron Charles Davillier, which has filtered out through various channels; some of it may be found in M. Gerspach’s work on glass (pp. 100-105). M. Schuermans also has not forgotten Spain in his records of the wandering Italian glass-makers (_Bulletin_ xxix., pp. 133-147). Footnote 183: In 1324 the glass-makers were ordered to remove their furnaces from the inside of the town (Riaño, p. 234). Footnote 184: A surviving vessel of this shape, as well as some examples taken from pictures by Bouts and by the so-called Mostaert, is illustrated by Mr. Hartshorne (_Old English Glasses_, p. 64). Other similar bowls were to be found in the Thewald collection (dispersed at Cologne, October 1903): in Germany such vessels are known as _halbe Wurzelbecher_. The form was imitated also at Venice, as we may see in a bowl, in this case duplicated, in the Waddesdon Room in the British Museum. Footnote 185:
