Grania and Diarmid

There are seven that pull the thread -
There is one under the waves,
There is one where the winds are wove,
There is one in the old grey house
Where the dew is made before dawn.
One lives in the house of the sun,
And one in the house of the moon,
And one lies under the boughs
Of the golden apple tree,
And one spinner is lost.
Holiest, holiest seven
Put all your pow'r on the thread
That I've spun in the house tonight.
