This is a first-pass attempt to translate the Orphic Hymn to the Kouretes with the help of the Liddell-Scott Greek-English Lexicon.
The Kouretes are armed dancers who make a loud clashing noise of swords and armor.
Kouretes (Κουρῆτες) is defined in the Lexicon as young men, especially young warriors. The base term, Kour- (Κουρ-) means youth, child, son, daughter. The Lexicon adds to its definition "armed dancers who celebrated orgiastic rites; at Ephesus, religious college of six members; a Pythagorean name for 9."
Legends tell of Kouretes dancing and making noise to conceal the birth of babies (Zeus, Apollo, Artemis) whom others wished to harm.
This Hymn would have been very loud and lively, with warriors in full armor leaping and dancing and clashing their armor noisily.
Diodorus Siculus, Library of History 5. 65. 1 (trans. Oldfather) (Greek historian C1st B.C.E.) :
"Nine Kouretes (Curetes). Some writers of myths relate that these [G]ods were born of the Gaia (the Earth)."
Strabo, Geography 10. 3. 19 (trans. Jones) (Greek geographer C1st B.C.E. to C1st CE.) :
"And the author of Phoronis speaks of the Kouretes . . . as earth-born (gigantes)."
Toward the end of the hymn, there is some indication that the Kouretes may have been charged with securing the sacrificial bull.
