Kritische Zeitschrift für die gesamte klassische Altertumswissenschaft (Gnomon: Critical Journal of the Entire Field of Scholarship on Classical Antiquity) is a German review journal covering the classics.

Since 1950, odd-numbered volumes contain a "Bibliographic Supplement" of new books, dissertations and submitted journal articles, in addition to the regular contents.

The editors-in-chief are Hans-Joachim Gehrke, Martin Hose, Henner von Hesberg, Ernst Vogt, and Paul Zanker.

[2] In both 2007 and 2011 the journal received an "INT1" ranking (internationally recognised with high visibility) from the European Reference Index for the Humanities.

Since the beginning of 1996 there has been a sister project, Gnomon Online, which provides access to the database through the internet and is updated weekly.
