Winged wheel
A winged wheel or flying wheel is a symbol used on monuments by the ancient Greeks and Romans and more recently as a heraldic charge. The symbol is mostly formed with one or two wheels and one, two, or three wings—with one wheel and two wings being the most common form.
The symbol was historically associated with the ancient Greek god Hermes and Roman god Mercury. In heraldry the symbol has been used to represent transport, speed and progress. It is an international symbol for railway transport, and still forms the basis of many railway company logos. Other modern uses are for sport, cycling and motorbikes.
