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 cursus and the cursus mixtus. The cursus involves the use of accentual rhythms and consists of three basic cadences: planus, tardus, and velox. The cursus mixtus has 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 cursus with one of the standard metrical forms derived from Cicero's system — cretic-spondee, dicretic, cretic-tribrach, or ditrochee.

In several recent studies we have developed precise statistical methodologies which have demonstrated that the cursus mixtus was the dominant rhythmical system for final clausulae in Latin prose from the third century a.d. to the fifth. The cursus mixtus consisted of four standard metrical forms derived from the richer variety of Cicero's Asiatic tradition – cretic-spondee, dicretic, cretic-tribrach and ditrochee –, which were structured according to three accentual patterns – planus, tardus and velox. The latter are differentiated by the number (...) of unstressed syllables intervening between and following two accented syllables. The planus has two unaccented syllables between two word accents and one after the last accent. The tardus has two between two accents and two after the last accent. The velox has four between two accents and one after the last accent. The four metrical forms are contained within the parameters of the accentual cadences. The planus contains either the cretic-spondee or the ditrochee ; the tardus either the dicretic or the cretic-tribrach ; the velox either the ditrochee or the cretic-spondee (nimium videbatur. Authors who used the cursus mixtus, however, preferred to effect an exact coincidence between the accent and ictus, and as a result evinced primarily the following standard rhythmical forms: planus/cretic-spondee; tardus/dicretic or cretic-tribrach; and velox/ditrochee. So far now we have examined only the rhythmical properties of final clausulae, but it is appropriate also to investigate for rhythm at internal positions within the sentence. (shrink)
