Why is Pisces first?

[Linda]

The 'ten month' year doesn't seem that likely. I thought the two missing months were best explained by the excised page at the end of the existing Zodiac pages

I agree, that's the best explanation. but perhaps it still does comment on the fact that such a calendar once existed. Or, sitting here in February, it seems like it might be a commentary on the lack of being able to do much with these 2 missing months, being in the dead of winter. Or perhaps it is commentary on the ages.
