Sun-wise (Re-post from misc to get crit)

[Brownlie]

Stone grinds out a diamond arc,
trilithons frame the heel.
Beasts of burden down from field,
parade around the fires wheel.

Rural beacons blind the night,
leapers launch above the flames,
marking out the crops new height,
all-fathers play their manly games.

Sun passes power onto leaf,
vervain, trefoil, rue and rose
sleep to dream of loves new lease,
the bard within reclaims belief.

It sounds good when I read it out loud but I'm missing something on the meaning. Is this some pagan society celebrating the sun and the harvest?
