are also accommodated in their "elaborately carved" stalls and the archbishop's throne or cathedra (symbolising the archbishop's authority and pastoral responsibilities) – designed by Pearson resides. The episcopal throne was carved in situ by Brisbane carver and cabinet maker Hedley Smith in the 1930s. Two statuettes by Smith were added in 1948. Beyond the choir is the presbytery and then the high altar and its surrounding sanctuary. The high altar is a free-standing structure with a great Byzantine-style stone baldacchino (a permanent ornamental canopy, as above a freestanding altar or throne), rather than a reredos, (a screen or a decorated part of the wall behind an altar in a church) supported on columns planned to rise high above it. Beneath the high altar lie the remains of Bishop Webber. However, as yet the baldacchino has not been constructed. In front of the altar in the sanctuary floor are two pieces of mosaic from the Holy Land, brought back after being uncovered during the First World War by the Australian Light Horse Regiment. One of these is part of the floor of a 6th-century synagogue at Jericho. The other is a fragment from the floor of a 6th-century Christian church at Gaza and is part of a larger mosaic now housed in the Australian War Memorial in Canberra. Beyond the high altar the cathedral ends in a semicircular apse and ambulatory (processional aisle), a link to the architecture's French-Norman past. Many features beyond the crossing including the altar, cross, candle sticks, pulpit, canopy, clergy stalls, pendant lights and litany desk were designed by Frank Pearson. He also designed the carved organ case and the rose window in the north transept. Many Brisbane architects were commissioned to design liturgical furniture for the cathedral's three chapels, the Lady Chapel, the Chapel of the Holy Spirit and the Chapel of the Holy Sacrament. The initial design called for a galvanised iron roof; this was changed to terracotta roof tiles in 1907. The resolution of unfinished design elements continues to pose challenges. Pews are being replaced by free-standing chairs. The baptismal font, previously in the north transept, has been moved to the west end of the nave. Bells The cathedral has a peal of 12 bells hung for full circle ringing with the tenor weighing 16 hundredweight. The first bells were made by John Warner & Sons in 1876 with funds raised by public subscription.
