As for the purpose of the VMS circles-of-nymphs, I've already blogged about what I think they are...
I don't think they they represent a calendar in the sense that we interpret the word (a time-keeping tool to keep track of months, days, etc.), I think they diagram a variety of human events that are time-related, like stages of life (from youth to old age), like menstruation, like the cycle of pregnancy, etc.
This is actually pretty logical. This kind of event is time-related, often cyclical, like the movement of the stars, the cycle of the moon.
