Cremona. Romanesque facades with oculi include San Miniato al Monte, Florence, 11th century, San Michele, Pavia, c. 1117, and Pistoia Cathedral, 1150. As the windows increased in size in the later Romanesque period, wheel windows became a standard feature of which there are fine examples at San Zeno Maggiore, Verona and Monza Cathedral. On the Romanesque façade of Spoleto Cathedral there is a profusion of recessed and traceried oculi surrounding the central features of a rose window set within a square beneath a large mosaic of 1207. In England there exist five Romanesque wheel windows, notably those at Barfreston and Castle Hedingham parish churches. St Denis, Chartres, Mantes, Laon and Paris The transition from the Romanesque style to the Gothic was not clear cut, even at the Abbey of St Denis, to the north of Paris, where the Abbot Suger, between 1130 and 1144, gathered the various newly emerging features of Gothic into a single building, thereby “creating” the Gothic style. Suger's original rose window in the prototype Gothic façade of St Denis probably pre-dates many of the remaining circular windows in Romanesque buildings such as those in England, at Trebic and Spoleto and that in the façade at Speyer. Suger's window was not distinctively Gothic in its appearance. It no longer has its original form, but a mid-19th-century drawing by the restorer Viollet-le-Duc indicates that it had a very large ocular space at the centre, the glass supported by an iron hoop, and surrounded by simple semicircular cusped lobes cut out of flat stone in a technique known as "plate tracery". The window now has Gothic tracery in it, possibly added by Viollet-le-Duc who was very concerned about the lack of stability of the whole façade, and having restored the towers, was impelled to demolish the northern one when it suddenly subsided. Along with the simple wheel windows of the late Norman period in England, Germany and Italy, a large late 12th-century window still exists at Chartres Cathedral. This remarkable window combines a large roundel at the centre with the radiating spokes of a wheel window, surrounded by a ring of smaller “plate tracery” lights with scalloped borders. The window, depicting the Last Judgement, contains its original scheme of glazing and retains much of the original glass of 1215, despite suffering damage during World War II. Following the west window of Chartres, more daring Gothic windows were created at
