The calendar takes the form of a table with thirteen columns, each of which is a month labelled with an abbreviation of its name. Still legible are the following:
IAN for
Ianuarius (January),
FEB for
Februarius (February),
APR for
Aprilis (April),
IVN for
Iunius (June), and
SEP for
September. Each column consists of several rows containing the days as well as a supplementary row indicating the total number of days in the month. Still visible are
XXIIX (28) for February,
XXIX (29) for April, June and partly for August,
XXXI (31) (partial) for May and October. Each day is marked with a letter from
A to
H, indicating the position of the day in the Roman
nundinal cycle, with occasional further letters appended to note the ceremonial category of the day: The first day of each month is marked by the letter
K, short for
Kalendae. The fifth day of January, February, April, June, August, September, November, and December is marked with the letters
NON, short for
Nonae, whereas
NON is placed in the seventh day for the months of March, May, July, and October. The eighth day after the Nones of each month is labelled
EIDVS (
Ides). Some days are marked with the letters
F,
N or
C.
F is short for
fastus dies ("allowed days", when it was legal to initiate action in the courts of civil law),
N for
nefastus dies (
banned days, when it was not), and
C for
comitialis dies (assembly days, when political assemblies were permitted). The calendar also lists the foundation dates (
dies natales) of the temples in the city of Rome. The fact that the foundation of the Temple of Venus connected to the
Theatre of Pompey is missing indicates that the calendar was created before 55 . The calendar also includes important events, like the
Ludi Megalenses, one of the festivals of the cult of
Magna Mater. The inauguration of her temple on the
Palatine occurred on 11 April 191 . The relevant festival took place from 4–11 April. A confirmation of the date of the
Ludi Megalenses is found in the
Fasti Quirinales, which additionally classify 11 April as
Endoitio Exitio Nefas. Later
Fasti contain a transmission error, which is why they provide the incorrect dates of 4–10 April. == References ==
