The ancient world lacked standardized practices of forensic science, which aided criminals in escaping punishment. Criminal investigations and trials relied on oaths, confessions and witness testimony. In a time when a distinction between science and such phenomena as religion, magic and superstition had not yet been made, some civilizations used practices such as the trial by ordeal to determine guilt or innocence. However, ancient sources contain several accounts of techniques that foreshadow the concepts of forensic science that were made possible by the Scientific Revolution centuries later. Predating the scientific method, these techniques were not based on a scientific understanding of the world in the modern sense, but rather on common sense and practical experience.〔 On the other hand, the development of an accurate way of measuring density by Archimedes marks a watershed in the use of objective methods, not just in forensics but also in physical science. ==Physical methods== The "Eureka" legend told of Archimedes (287–212 BC), where the philosopher proved that a crown was not solid gold by comparing measurements of its displacement of water and its weight, is a direct forerunner of modern forensic engineering techniques.〔Schafer, 41.〕 The case marks a critical point when quantitative methods become vital, as well as establishing the concepts of density, buoyancy, force and equilibrium. The first recorded example of forensic dentistry may be the account of Agrippina, the Roman emperor Nero's mother, who sent for the head of her enemy Lollia Paulina to verify her death. While the face was distorted beyond recognition, Agrippina could recognize a distinctively colored front tooth that she had previously noticed in Lollia’s mouth.〔 The Old Testament story of the ''shibboleth'', in which the victorious Gileadites identified (and killed) the vanquished Ephraimites because they could not properly pronounce the word "shibboleth", foreshadows modern voice identification techniques.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Forensics in antiquity」の詳細全文を読む スポンサード リンク
