Crux is an American comic book published by Cross Gen Entertainment from May 2001 to February 2004. It was cancelled due to bankruptcy in 2004. Crux was one of the later titles that came first in a sort of second wave of Crossgen titles which included Sojourn and Brath.
Crux (Latin for "cross," or "torment") is the term apllied 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 the latin term crux interpretum, "torment of interpreters") presents difficulty in interpretation and resolution—if, indeed, resolution is possible. Cruxes occur in a wide range of pre-modern (ancient, medieval, and Renaissance) texts, printed as well as manuscript.
