The period is given a number of different names by
Cicero,1 who calls it ambitus, circuitus, comprehensio,
continuatio and circumscriptio. It has two forms. The
one is simple, and consists of one thought expressed
in a number of words, duly rounded to a close. The
other consists of commata and cola, comprising a
number of different thoughts: for example, aderat
ianitor carceris, carnriex praetoris2 and the rest.
