Edited sentence: In his reform of modal theory in the Dodecachordon (1547), Heinrich Glarean named this division of the octave "Hyperaeolian" and printed some musical examples (a three-part polyphonic example specially commissioned from his friend Sixtus Dietrich, and  the Christe from a mass by Pierre de La Rue), though he did not accept Hyperaeolian as one of his twelve modes.The usage of the term "Locrian" as equivalent to Glarean's Hyperaeolian or the ancient Greek (diatonic) Mixolydian, however, has no authority before the 19th century
