The 'Chinese' Theory: For and Against

[eggyk]

Keep in mind that „mars“ is written in complete different alphabet, ink, language, positioning and style, compared to original page. Possibly also in a completely different time.
Maybe that helps with viewing the original work of the VMS „zodiacs“ — whenever the months‘ names were added.

Precisely, a february label would have been extremely useful to work much of that out, as it's a name that varies quite strongly across regions and centuries compared to other months. 

But in any case, I only mention it because a perefectly equal 15/30 is being used as evidence of eastern astrology in this discussion. One of the months being 29 raises questions there that have to be answered.

You can say that the 29 is a mistake, and that it was meant to be 30 in line with eastern astrology. If you do that, though, you can start stating that the lack of 31 days are also mistakes in a western astrology depiction. 

A third option of course is a seperate astrology (in either area) that used 29 for a month, and 30 for the rest. I don't have any evidence for or against that, of course. But it is worth thinking about.
