In two recent studies we have examined the prose rhythms in the clausulae of late imperial Latin authors. We found two clausular systems to be prevalent, the
cursusand the cursus mixtus. The cursusinvolves the use of accentual rhythms and consists of three basic cadences: planus, tardus, and velox. The cursus mixtushas been defined by modern scholars as a type of prose rhythm in which the clausula is structured along both accentual and metrical lines, that is by the combination of one of the three forms of the cursuswith one of the standard metrical forms derived from Cicero's system — cretic-spondee, dicretic, cretic-tribrach, or ditrochee.
