Textual criticism originated in the classical era and its development in modern times began with classics scholars, in an effort to determine the original content of texts like Plato's "Republic". There are far fewer witnesses to classical texts than to the Bible, so scholars can use stemmatics and, in some cases, copy text editing. However, unlike the New Testament where the earliest witnesses are within 200 years of the original, the earliest existing manuscripts of most classical texts were written about a millennium after their composition. All things being equal, textual scholars expect that a larger time gap between an original and a manuscript means more changes in the text.
