even stocks otherwise closely related differed in their mode of
fixing the commencement of day, the Romans placing it at midnight,
the Sabellians and the Etruscans at noon. No calendar of the year
had, at least when the Greeks separated from the Italians, as yet
been organized, for the names for the year and its divisions in the
two languages have been formed quite independently of each other.
Nevertheless the Italians appear to have already in the pre-Hellenic
period advanced, if not to the arrangement of a fixed calendar,
at any rate to the institution of two larger units of time. The
simplifying of the reckoning according to lunar months by the
application of the decimal system, which was usual among the Romans,
and the designation of a term of ten months as a "ring" (-annus-)
or complete year, bear in them all the traces of a high antiquity.
Later, but still at a period very early and undoubtedly previous
to the operation of Greek influences, the duodecimal system (as
we have already stated) was developed in Italy, and, as it derived
its very origin from the observation of the fact that the solar
period was equal to twelve lunar periods, it was certainly applied
in the first instance to the reckoning of time. This view accords
with the fact that the individual names of the months--which can
only have originated after the month was viewed as part of a solar
year--particularly those of March and of May, were similar among
the different branches of the Italian stock, while there was
no similarity between the Italian names and the Greek. It is not
improbable therefore that the problem of laying down a practical
calendar which should correspond at once to the moon and the sun--a
problem which may be compared in some sense to the quadrature of the
circle, and the solution of which was only recognized as impossible
and abandoned after the lapse of many centuries--had already employed
the minds of men in Italy before the epoch at which their contact
with the Greeks began; these purely national attempts to solve it,
however, have passed into oblivion.

The Oldest Italo-Greek Calendar

What we know of the oldest calendar of Rome and of some other Latin
cities--as to the Sabellian and Etruscan measurement of time we
have no traditional information--is decidedly based on the oldest
Greek arrangement of the year, which was intended to answer both
to the phases of the moon and to the seasons of the solar year,
