In some hymnals, the editors noted that a hymn's author is unknown to them, and so this artificial "person" entry is used to reflect that fact. Obviously, the hymns attributed to "Author Unknown" "Unknown" or "Anonymous" could have been written by many people over a span of many centuries. Go to person page >
May God bless you.
May God keep you.
May God be gracious and look kindly on you.
And may the Lord's face shine upon you
and give you peace, give you peace.
