Textual critic

Textual criticism is a branch of textual scholarship, philology, and literary criticism that is concerned with the identification of textual variants in either manuscripts or printed books. Scribes can make alterations when copying manuscripts by hand. Given a manuscript copy, several or many copies, but not the original document, the textual critic might seek to reconstruct the original text (the archetype or autograph) as closely as possible. The same processes can be used to attempt to reconstruct intermediate versions, or recensions, of a document's transcription history. The objective of the textual critic's work is a better understanding of the creation and historical transmission of texts. This understanding may lead to the production of a "critical edition" containing a scholarly curated text.

There are many approaches to textual criticism, notably eclecticism, stemmatics, and copy-text editing. Quantitative techniques are also used to determine the relationships between witnesses to a text, with methods from evolutionary biology (Phylogenetics) appearing effective on a range of traditions.

In some domains (religious and classical text editing) the phrase "lower criticism" is used to describe the contrast between textual criticism and "higher criticism", which is the endeavor to establish the authorship, date, and place of composition of the original text.

Textual criticism has been practiced for over two thousand years. Early textual critics, especially the librarians of Hellenistic Alexandria in the last two centuries BC, were concerned with preserving the works of antiquity, and this continued through the medieval period into early modern times and the invention of the printing press. Textual criticism was an important aspect of the work of many Renaissance Humanists, such as Desiderius Erasmus, who edited the Greek New Testament. In Italy, scholars such as Petrarch and Poggio Bracciolini collected and edited many Latin manuscripts, while a new spirit of critical enquiry was boosted by the attention to textual states, for example in the work of Lorenzo Valla on the purported Donation of Constantine.
