Truro Cathedral has three rose windows: one on the West wall, and one in each transept. They were all manufactured by Clayton & Bell. These windows exemplify the vibrant colours and bold designs that make Truro’s stained glass some of the finest Victorian glass to be found in the country. • The West rose window (top) celebrates God the Father, the first member of the Trinity. It is divided into seven segments for the seven days of creation. It is the first in the set of three such rose windows, celebrating the three Persons of the Trinity. We shall see that the black framed squares and circles form a unifying link with the other windows. • Jesus, the Son of God, is at the heart of the North transept rose surrounded by the prophets and his antecedents: Jacob, Isaac, Judah and Abraham, leading through to Mary and Joseph. • The beautiful rose window in the South transept (bottom right) has interesting mathematical symmetry. The central disk features a white dove representing the Holy Spirit. This is surrounded by worshipping angels.
