118 the intercalation by marks placed on the horizon, to denote where the sun rose and set on the days of the solstices and equinoxes. Observations of the sun were taken each month.

There is some want of agreement among the authorities who give the names of the months. Some have the same names, but they are not given to the same months, while others have different names. After a careful analysis I have come to the conclusion that the list given by Calancha, Polo de Ondegardo, Acosta, Morua and Cobos, which is the one accepted by the second Council of Lima, is the most correct. Each one of the other authorities has more names in agreement with the Calancha list than with any other. Acosta is in complete agreement as far as he goes, but only gives eight months.

The correct calendar was, I believe, as follows:

June 22 to July 22. (June 22), Winter Solstice. Harvest Festival. July 22 to Aug. 22. Aug. 22 to Sept. 22. (Sept. 22), Spring Equinox. Expiatory Festival. Sept. 22 to Oct. 22. (Sept. 22), Spring Equinox. Oct. 22 to Nov. 22. Nov. 22 to Dec. 22. (Dec. 22), Summer Solstice. Or Dec. 22 to Jan. 22. (Dec. 22), Summer Solstice. Huarachicu Festival. Jan. 22 to Feb. 22.
