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 >
Come, thou long expected Jesus,
born to set thy people free;
from our fears and sins release us,
let us find our rest in thee.
Israel's strength and consolation,
hope of all the earth thou art;
dear desire of every nation,
joy of every longing heart.
