Апостольская церковь
In Germany, Worms Cathedral, has wheel windows in the pedimental ends of its nave and gables, very similar to the Early Christian Basilica of S. Agnese in Rome. The apsidal western end has a central wheel window with smaller oculi in each face. The Church of the Apostles, Cologne has an array of both ocular and lobed windows forming decorative features in the gables and beneath the Rhenish helm spire. The octagonal dome has a ring of oculi with two in each of the curved faces.
