introduced at the crossing of the centre mullion and transom, which resembles the treatment adopted in the screen at King's College Chapel (Plate VIII.). The date of Layer Marney may be put at 1520, Lacock Abbey at about 1540, and the screen at 1535. The greatest development of windows was, however, to be found in the bay. The bay window is one of the most important features in the architecture of the time. English designers had always been fond of bay windows: they put them to the daïs of their halls in quite early times, and there are many examples of small bays being corbelled out on an upper floor, where the exigencies of the ground plan did not permit of their starting from the ground. But as a rule these early bays were only one storey in height: as time went on, however, they grew to two storeys, and then to as many as the main building itself had. From being an adjunct they became a dominating feature, and most of the large houses of the time derive variety of outline and rhythm of composition from their bay windows. Hoghton Tower, in Lancashire (Fig. 94), has a fine bay at the end of the hall. It is only one storey high, but that storey is the full height of the building in that part. The sill is brought down lower than those of the other windows in order to enable the occupants of the daïs to look out into the court. At Astley Hall, also in Lancashire (Plate XXXIII.), the two bays are the dominating feature of the front; indeed, the whole architectural interest of this side of the house lies in the management of the windows, for the doorway, flanked by double columns which lend their united strength to supporting a peaceable lion, is hardly worth attention. The long range of windows which reaches continuously from one end of the building to the other forms a striking feature, but must be a matter of much concern to the housewife who has to drape them on the inside, and to consider the claims of her carpet on sunny days.
