Flos Carmeli...
has a link to an online version of the poem "Christ" by Cynewulf. It is written in English prose, and its rendering of the two most famous lines in the poem leaves something to be desired. It has

"Lo ! Thou Splendor of the dayspring, fairest of angels sent to men upon earth..."

This is a translation of

Éala Éarendel Engla Beorhtast
Ofer Middangeard Monnum Sended

A closer rendering would be

"Hail, Earendel, brightest of angels
Over Middle-earth sent to men..."

These lines intrigued the young Tolkien, who developed the character and story of Eärendil from this slender hint. This was one of the earliest seeds of the entire Legendarium.
