Contrary to what one might think after viewing some of the forensic investigation shows on television programs that show off the latest in modern (and sometime wishful) forensic science devices and techniques, forensics has a long history. From a time of slow advance in ancient Babylon when fingerprints were pressed into clay tablets to cement business transactions, through a time in circa 250 BC when Erasistratus, a Greek physician noticed that, when his patients lied, their pulse rates increased, through the time in 44 BC when Antistius, a Roman physician, counted the 23 stab wounds in Julius Caesar's body to establish a cause of death, to the present time, the rate of advancement in forensics has been steadily increasing. Various specialized fields have developed and expanded to include subfields. As a result, the number and size of documents that describe the growing number of forensic specialties has seemingly grown exponentially.
