Crux (Latin for "cross", "gallow", or "t-shape") is a term applied by palaeographers, textual critics, bibliographers, and literary scholars to a point of significant corruption in a literary text. More serious than a simple slip of the pen or typographical error, a crux (probably deriving from Latin crux interpretum = "crossroad of interpreters") is difficult or impossible to interpret and resolve. Cruxes occur in a wide range of pre-modern (ancient, medieval, and Renaissance) texts, printed and manuscript.
