I got very badly stuck on this one and then I woke up this morning and went - well, it's a hymn so translate it as one. So, unlike most of my poems, this one is singable - it may not be great verse but it is singable.
Specifically, it is singable to the tune that used to be known to every Catholic, actual or lapsed, as 'Mother of God, Star of the sea'. Since the Church appropriated all sorts of ideas from pagan worship, it seems fair to steal something back...
Pure boys and maidens We sing to thee Diana Queen of Chastity
Latona on fair Delos isle rested under an olive tree bore you and watched the infant smile Greatest of all Jove's progeny
Pure boys etc.
Mistress of every wooded peak and of secluded forest glades of swift high streams that foaming speak and of the fields the forest shades
Pure boys etc.
patron of women that give birth and the reliever of their woe queen of each crossroad on the earth, as moon across the sky you go
Pure boys etc.
As moon you shed light on the soil bringing the seasons round in turn blessing the humble farmer's toil bringing the harvest that he'll earn
Pure boys etc.
We worship you by every name in every shape and aspect too You have helped Rome; please be the same to all of us who worship you
