"The poor fellow-soldiers of Jesus Christ of the Temple of Solomon"--for such was the full designation of the Templars in commemoration of the quarters assigned them within the area of the former Jewish Temple--naturally had their thoughts turned towards Jerusalem, wherever they were stationed. The design of the church which Heraclius consecrated was determined by the circular chapel which stood on the site of the Old Temple in Holborn, and the prototype of both buildings was the Church of the Holy Sepulchre at Jerusalem, with which English Templars must have been familiar from the earliest days of the Order. The travels of Templars and Crusaders undeniably influenced English architecture. One such influence we find in the constructive use of the pointed arch, which is said to have been introduced about 1125 from the South of France--a route which Norman Crusaders frequently followed. For many years after that date pointed and round arches were used almost indifferently in Norman work, so that the strongly pointed arches of the Round Church are not in themselves decisive of the date of the building. It is not till about 1170 that the real transition from Norman to Early English can be said to have begun. In the interior of the Round Church this movement is in full swing. The lower arcade has been inaccurately restored and must not be taken as evidence, but in the decorative band of arcading on the upper wall which frames the openings into the triforium we see how the intersection of two semi-circular arches gives the pure lancet form. The crucial point, however, is the absence of the massive Romanesque columns which invariably mark true Norman work. In their place we have columns of comparative slenderness, each consisting of four almost insulated shafts of Purbeck marble, two smaller and two larger. These columns must be among the earliest examples of their kind in England. There is a somewhat similar treatment (two shafts only, as originally designed) in the Galilee of Durham Cathedral, built a few years later, whereas in the choir of Canterbury Cathedral, which was rebuilt only a few years before 1185, the Romanesque columns are still retained, though the style of the capitals is modified.
