Signs advertising business premises have been around for thousands of years and were used in ancient Egypt, Greece and Rome to attract customers; and they often used symbols to illustrate what kind of business it was - for example, bushes or branches of ivy meant the place was a tavern. Both of these, the tavern and its sign, were introduced into Britain by the Romans in the first half of the 1^st century AD. In Europe in the Middle Ages signs became more common, then, in the 14^th century, English merchants were obliged to have them outside their shops. However, the fashion was to have large swinging signs hung from a strut sticking out of the wall - and many public houses still have such signs - but so many accidents occurred, mostly involving people on horseback, that in the 17^th century a law was brought in requiring shopkeepers to mount their signs flat against the wall of the premises, where they could do no harm.
