Maroquin
The coach weighs four tons and is long and high. It is gilded and features painted panels by Giovanni Battista Cipriani and rich gilded sculpture including three cherubs on the roof (representing England, Ireland and Scotland) and four tritons, one at each corner (representing Britain's imperial power). The body of the coach is slung by braces covered with Morocco leather and decorated with gilt buckles. The interior is lined with velvet and satin. The sculptor Sir Joseph Wilton produced the elaborate carvings on the coach. The roof supports three cherubs representing the union of England, Scotland and Ireland. They carry the Imperial Crown and hold the sword, sceptre and the badge representing Knighthood. The branches of eight gilded palm trees frame the roof. Four corner trees rise from a lion's head and are decorated with symbols of Britain's victory in the Seven Years' War with France. The war was drawing to a close when the coach was built in 1762. Morocco leather straps support the body of the coach and are held by four Triton, mythical sea-gods with a man's head and a dolphin's tail. At the front wheels, the tritons seem to be using the straps to pull the coach. They are blowing conchs, trumpet-like shells to herald the arrival of the Monarch of the Ocean. Gilded dolphins hold in place the bar by which the coach is drawn, and the driver's foot board (no longer used) is in the shape of a scallop shell. The two tritons at the back carry imperial symbols, representing Britain's maritime traditions and status as a dominant sea power.
