Plate XCVIII. Open Screens with a Central Way

Plate XCVIII. — An open screen of columns giving a central way for wheeled traffic, and two openings for pedestrians, is given in No. I: it is an example of extreme simplicity and grace. Fig. II represents the famous screen placed in advance of a number of doorways and forming a loggia at Hampton Court Palace, designed by Sir Christopher Wren: the coupled columns are carefully adjusted between wing walls to give rhythm to seven bays. The screen used in a complex manner is shown in No. III: in this design will be found a fine solution of the problem of connecting two groups of buildings across the face of an open courtyard, where it is necessary to leave the ground floor comparatively open and to provide circulation under cover at an upper level.
