The chasuble is dated to circa 1430-1440 and depicts a subject which comes up far too infrequently in vestment work, the Transfiguration. On the back of the chasuble, within the orphrey, Christ is shown transfigured on the mountain top with St. Peter, St. James and St. John below and God the Father, Moses and St. Elias above. Surrounding this are various architectural niches in a honeycomb like pattern which contain angels.
One will note how the orphrey actually overlaps the underlying textile with its angels. Indeed, this chasuble seems to have three layers, one set on top of the other: the main body of the chasuble, the orphrey and the large figures.
On the front of the chasuble we find the Baptism of Christ in the Jordan by St. John the Baptist. Above are found the other Two Persons of the Holy Trinity in yet another depiction of God the Father and the dove symbolizing the Holy Spirit. As with the back, numerous other angelic beings decorate the rest of the chasuble.
