The night sky (ragi) was moving (walking) because in the Golden Age of the Bull - when the calendar dates had been definitely coordinated with the seasons of the Sun - the change from winter to summer was beginning when the Sun reached the northern point of the pair of horns of Taurus. There were 48 days for this magic transformation of Mother Nature.

Beltane came after 121 - 95 = 26 of these 48 days:

And these 26 days corresponded to the right ascension distance σ Aurigae (80.4) to ω Gemini (*105.4), both central stars in their constellations:

The current dates in the Gregorian calendar were intended to correspond to those extrapolated to the Golden Age of the Bull. Therefore the current date November 18 (322) should corresponded to NOVEMBER 18 (322) = MAY 18 (138) + 184:

When the Sun was rising in the east he came up from the sea and this could have motivated the design with a fish tail at bottom.
