Imagine, you are living in the early 1800s. You are from a wealthy family and you are lucky enough to enjoy lots of luxuries, including beautiful furniture and china. Of course, having beautiful things means that you have to look after them too - you don't want to loose them to a thief! Luckily, your doors, and the beautiful objects behind them, have vert solid locks so any thief would have a lot of trouble getting in. You're just glad it isn't your job to carry the keys - they're huge and weigh so much!

These keys are one of the most popular items I share with children, and they are often used to accessorise imaginary play scenarios. Indeed, many children suggest that 'they're so big, they must be toys. There aren't any locks that big!' Children today have never seen such big, ornate keys before - to them, keys are small and lightweight, easily carried in a pocket or handbag. These keys though are like nothing they have seen before, because not only are they massive, they are very heavy. Not only that, the keys appear to be handmade, which makes them even more intriguing - just imagine the effort which went into forging these individual, beautiful keys!

The history of keys is, of course, irrevokably tied with the history of locks and since people first had nice things which they wanted to keep safe, they have needed locks and keys. The history of keys and locks dates back thousands of years, right back to the Egyptians, Greeks and Romans. The oldest existing lock is about 4000 years old, was Egyptian and was probably quite common at the time it was made. It used a wooden bolt as the lock securing the door, and then had a series of holes in the wood which would be filled by wooden pegs to stop the lock being opened.In fact, it was this which was the forerunner of our modern locks! The pegs fell into the holes automatically, like the tumblers in modern locks, and they had to be lifted back out again to allow the lock to be opened. At first a handshaped hole in the door allowed the lock to be opened (so the hand was the first 'key') but later long, thin, wooden 'keys were used. The Greeks used locks to keep Temples and sacred places safe, and women carried large angular 'keys' over one shoulder. In fact, it was apparently the Greeks who invented the keyhole as we know it, though the Romans are the ones who refined it. At this time, particularly in Rome, having keys was quite a status symbol because it showed you had things which were worth protecting.The Romans also improved on Egyptian locks by adding 'wards' which the key had to get past before the tumblers could be removed. Apparently the portable lock (padlocks) were also invented by the Romans, though they were also independantly invented in China.

Throughout history, locks continued to be improved, and although by Medieval time locks were a little more complicated, the main innovation in lock and key history was to make them beautiful. They made exquisitely embellished locks and beautifully decorated keys which were not only secure, but also attractive. These early locks were still quite easy to 'pick' for a determined thief. In the late 1700s and early 1800s though these locks were improved upon. In 1778 Robert Barron created a lock which had two sets of tumblers which had to be raised to exactly the right height to allow the door to be opened. In 1818 Jeremiah Chubb further improved on this by adding a spring which would catch and hold the tumbers if they were lifted to the wrong position by a thief. This not only made the lock more secure, only able to be opened by the correct key, but it also made it possible to tell if a lock had been tampered with.
