lded.... On these the Indians painted the accounts of their years,
wars, inundations, famines, hurricanes, and other events. From one of
them, which Dr. Aguilar took away from some Idolaters, it was learned
that in ancient times there was a plague called _Mayacimil_ and also
another called _Ocna Kuchil_, which is to say Sudden Deaths, and
Times-in-which-ravens-entered-the-houses-to-eat-the-corpses. Inundation
and hurricane they called _Hunyecil_, Overflowing-of-trees....

"They counted the year as having 365 days, divided into months of
twenty days each, corresponding to ours in this order:

Jan. 12-Feb. 1 was Yaax July 11-July 17 was Vayeab
Feb. 1-Feb. 21 " Zac July 17-Aug. 6 " Poop
Feb. 21-Mch. 13 " Ceh Aug. 6-Aug. 26 " Voo
Mch. 13-Apr. 2 " Mac Aug. 26-Sept. 15 " Cijp
Apr. 2-Apr. 22 " Kan Kin Sept. 15-Oct. " Zeec
Apr. 22-May 12 " Muan Oct. -Nov. " Zul
May 12-Jun. 1 " Paax Nov. -Dec. " Yax Kin
Jun. 1-Jun. 21 " Kayab Dec. -Dec. " Mool
Jun. 21-July 11 " Cum Ku Dec. -Jan. 11 " Cheen

By this count the year was divided into eighteen months, but their year
began on the seventeenth of our July. The five days which were lacking
to complete the 365 were called Nameless Days. They held them to be
melancholy, and they said that on them happened disastrous deaths and
unforeseen events, such as stings and bites from poisonous snakes and
wild or venomous animals as well as quarrels and dissensions; and they
especially feared the first of these days. During this period they
tried not to go out of their houses, and so they always provided
themselves with what was necessary beforehand so as not to have to go
to the fields or elsewhere. At this time they attended especially to
their Heathen Rites, begging their Idols to keep them free from harm in
those dangerous days and to grant that the following year might be
fertile and abundant. And these days so greatly feared were the 11, 12,
13, 14, 15 and 16 (sic) of our July. All the days of the month had each
its name, which I leave untold for fear of prolixity.

"By means of this count they know the time in which to clear the
woodlands and to burn the underbrush, to expect rains, to sow the Maize
and other vegetables, for all which actions they have their Proverbs.
The first Religious (says Aguilar), holy men, and true Keepers of the
Vineyar
