My absolute favorite reading for Summer Solstice rituals is Orphic Hymn 7: To the Sun. Thomas Taylor's translation might not be perfectly accurate word for word, but his poetic license captures the grandiose feeling of a hymn perfectly. Read it like you're holding a skull on a theatre stage.
"Hear golden Titan, whose eternal eye with broad survey, illumines all the sky.
Self-born, unwearied in diffusing light, and to all eyes the mirrour of delight:
Lord of the seasons, with thy fiery car and leaping coursers, beaming light from far:
With thy right hand the source of morning light, and with thy left the father of the night.
Agile and vig'rous, venerable Sun, fiery and bright around the heav'ns you run.
Foe to the wicked, but the good man's guide, o'er all his steps propitious you preside:
With various founding, golden lyre, 'tis mine to fill the world with harmony divine.
Father of ages, guide of prosp'rous deeds, the world's commander, borne by lucid steeds,
Immortal Jove, all-searching, bearing light, source of existence, pure and fiery bright
Bearer of fruit, almighty lord of years, agil and warm, whom ev'ry pow'r reveres.
Great eye of Nature and the starry skies, doom'd with immortal flames to set and rise
Dispensing justice, lover of the stream, the world's great despot, and o'er all supreme.
Faithful defender, and the eye of right, of steeds the ruler, and of life the light:
With founding whip four fiery steeds you guide, when in the car of day you glorious ride.
Propitious on these mystic labours shine, and bless thy suppliants with a life divine."
