I'm gonna have to be very Finnish because my fave opening is from the Kalevala. Also the only beginning I can quote from memory.
Original:
Mieleni minun tekevi, aivoni ajattelevi
lähteäni laulamahan, saa'ani sanelemahan,
sukuvirttä suoltamahan, lajivirttä laulamahan.
Sanat suussani sulavat, puhe'et putoelevat,
kielelleni kerkiävät, hampahilleni hajoovat.
Translation:
Mastered by desire impulsive,
By a mighty inward urging,
I am ready now for singing,
Ready to begin the chanting
Of our nation's ancient folk-song
Handed down from by-gone ages.
In my mouth the words are melting,
From my lips the tones are gliding,
From my tongue they wish to hasten;
When my willing teeth are parted,
When my ready mouth is opened,
Songs of ancient wit and wisdom
Hasten from me not unwilling.
