The oldest keys known to exist date from around 4,000 BC in Ancient Egypt. These were simple wooden cylinders that were part of a mechanism to secure doors. By the time of the Roman Empire, metal keys were in common usage and had begun to adopt the recognizable pattern of keys today. This book tells the complete story of the key, backed by numerous photos from all time periods.
Today, old keys are more than just security mechanisms. They are highly collectable artifacts that can either be artistically beautiful or coldly functional, but either way, they can help us unlock the secrets of the past.
The world of locks and keys is fascinating. The book, gives interesting and detailed information on the history of keys / locks from Egyptian times to the 20th Century. Describing her made them, how were they made and discussing the working conditions of some key and lock makers. The book is illustrated with black and white photos and simple black outlined drawlings. Some people may find the detail a little bit dry, but I looked upon it as fascinating. For the collectors, there is suggestions of where to buy such objects, how much you may pay for it. Also how to clean your key and what not to do. Lastly information of furter reading and what museums to visit in the UK, to view old samples of keys and locks. Overall an excellent book on a niche subject.
