there is an excellent british doco that either the abc or sbs played a number of times in recent years - it was about the ancient celts being a matriarchal society that worshiped the moon - not the sun as previously believed - and stonehenge and the famous scottish mound one - were actually being built more around worshipping the moon than the sun - EDIT: i should of said - is a general astronomical observatory - but more a lunar observatory) for the life of me I cant find its name on the web
but it was very much about this topic and the standstill years and the cycle - the standstill years being of special significance to them -and that stonehenge was made to highlight the standstill years in the cycle - the sun wasnt the main interest at all
it had many great animations dealing with the cycles - very educational!
from memory they talked about the moon bobbing up in down in its orbital plane like in a wave situ (I think the earth bobs up an down as well)
not being a big moon worshipper i have to concede i havent taken a great interest in this cycle much
