Textual criticism involves examination of the text itself and all associated manuscripts with the aim of determining the original text. It is one of the largest areas of biblical criticism in terms of the sheer amount of information it addresses. The roughly 900 manuscripts found at Qumran include the oldest extant manuscripts of the Hebrew Bible. They represent every book except Esther, though most books appear only in fragmentary form. The New Testament has been preserved in more manuscripts than any other ancient work, having over 5,800 complete or fragmented Greek manuscripts, 10,000 Latin manuscripts and 9,300 manuscripts in various other ancient languages including Syriac, Slavic, Gothic, Ethiopic, Coptic and Armenian texts. The dates of these manuscripts are generally accepted to range from c.110–125 (the papyrus) to the introduction of printing in Germany in the fifteenth century. There are also approximately a million direct New Testament quotations in the collected writings of the Church Fathers of the first four centuries. (As a comparison, the next best-sourced ancient text is the "Iliad", presumably written by the ancient Greek Homer in the late eighth or early seventh century BCE, which survives in more than 1,900 manuscripts, though many are of a fragmentary nature.)
