The taka-ure spirits at the beginning of line Gb3 could refer to the flying horse Pegasus, and the 'nose' (the beginning) of this season probably was at heliacal Enif (ε) - and possibly also the reason for the exaggerated nose in Gb2-10:

 

February 13 was also where the Goat reached his tail end (Deneb Algiedi):

... Februa, also Februatio, was the Roman festival of ritual purification, later incorporated into Lupercalia. The festival, which is basically one of Spring washing or cleaning (associated also with the raininess of this time of year), is old and possibly of Sabine origin. According to Ovid, Februare as a Latin word which refers to means of purification (particularly with washing or water) derives from an earlier Etruscan word referring to purging.

The Roman month Februarius ('of Februa', whence the English February) is named for the Februa/Februatio festival, which occurred on the 13th to 15th days of this Roman month. A later Roman god Februus personified both the month and also purification, and is named for them. Thus, the month is named for the festival and not for the god ...

He was raised to the status of a god (among the other gods of the state) under the name Jupiter Julius. Marcus Antonius, who this year was consul together with Ceasar, became high priest and responsible for the ceremonies. In the middle of February, at the time of the old feast of Lupercalia, he ran around naked (except for a girdle - like a maro), and whipped the Roman ladies with thongs made from goat-skin, in order to promote ... their fertility ...

A month later Pegasus was still there and the figure ended at χ, at the chain which held Andromeda in place. The beginning of the Square was where the pair Scheat (β) and Markab (α) rose with the Sun (*349) and the end of the Square was at Algenib (γ) together with the head of Andromeda in March 22. The measure of this Square was *366 - *349 = 17 days.
