YOU'VE HEARD OF THE LORD'S PRAYER IN ARAMAIC, but how about the Lord's Prayer in Elvish? Translated by Tolkien himself:

�taremme i �a han �a
na aire esselya
aranielya na tuluva
na care ind�melya
cemende tambe Erumande :
�men anta sira ilaur�a massamma
ar �men apsene �caremmar
s�v� emme apsenet tien i �carer emmen.
�lame tulya �saht�enna
mal �me etelehta ulcullo
: n�sie :
