Editing Rose window (section)

=== The windows of Oviedo ===
In the vicinity of [[Oviedo]] in Spain are several churches of the late 9th and early 10th century which display a remarkable array of windows containing the earliest examples of roses windows outside the [[Byzantine Empire]].  The designs closely resemble the motifs found on the Byzantine relief carvings of marble [[sarcophagus|sarcophagi]], [[pulpit]]s and well heads and pierced decorations of screens and windows of [[Ravenna]] and [[Constantinople]]. The church of [[Church of San Pedro de Nora|San Pedro de Nora]] has at its apsidal end a trio of rectangular windows with pierced decoration of two overlapping circles, the upper containing a [[Greek cross]], the window being divided by the circles and the arms of the cross into numerous sections like tracery "lights".

In another of these churches, [[San Miguel de Lillo]], is the earliest known example of an axially placed oculus with tracery. Several such windows of different sizes exist, and decoration of both Greek Cross and scalloped petal-like form occur, prefiguring both wheel and rose windows.
