Ridges were of tile or stone. A fragment in the Reading Museum from Silchester has a knob rising from the saddle-back of a ridge-tile strangely mediæval in appearance (Fig. 8). Probably one came at each end of the ridge only (cf. V. le Duc’s “Faîtière”). Ridges were frequently terminated by stone gable knobs, which have been found in many places (see Ward’s _Roman Buildings_), and occasionally in such a position as to show that a gable end fronted a street. A ridge termination in Exeter Museum is shown upside down as if it were a corbel (Fig. 15 is a memory sketch, and compare Fig. 16 from Bath). These terminations are late derivations from acroteria and prototypes of gable crosses; they are links in a continuous chain from Greek to Gothic. [Illustration: FIG. 17. ] Little joiner’s work has survived to our day. Doors would not have been very different from our own, as is shown by many examples of framed panel work from foreign sites in museums. A bronze pivot in the Museum at Westminster Abbey must have been a hinge of a door (Fig. 17). Iron strap-hinges in the museums are very similar to our own. There are two in the British Museum (Fig. 18). The plane found at Silchester is evidence for joiner’s work. In Leicester Museum is a fragment of a lion’s head and leg from a piece of furniture—probably a table. Turning in a lathe was practised, as some wooden dishes at the Guildhall show. There are many excellent locks and keys and hinges and handles in our museums. [Illustration: FIG. 18. ] The use of window glass was very general. It was cast in small panes, as is shown by the large proportion of existing fragments which have edges and corners. Practically a whole pane, about 12 in. by 12 in., is in the Rochester Museum. Near Warrington, on a Roman site, was found a stone slab with a shallow recess 12 in. by 8 in., which Mr. May regarded as a mould for glass (Ward). The average size of panes would have been about one Roman foot long. Glassware seems to have been made in London, Silchester and elsewhere, doubtless from imported “metal.” Some windows, possibly unglazed, were protected by iron gratings. An iron star X in the Guildhall Museum came from such a window guard as is shown by a complete example I sketched many years ago in the Strasbourg Museum (see _Arch. Rev._, May 1913) (Fig. 19). It had been suggested that such X-pieces were “holdfasts,” to keep the glass panes in position (Ward); but this is not the case; moreover, the pane at Rochester shows that it was “cemented” into place. [Illustration: FIG. 19. ] Lead must have been largely used; there are a dozen large “pigs” in the British Museum. Melted lead was found at Verulam in a position which suggested that it had been used on an important building. In the Guildhall Museum are some sections of lead water-pipes found in London, and at Westminster Abbey is a piece 4 in. in diameter, which must, I think, be Roman (Fig. 18, C).
