Achelous

Swimming through the rivers of Earth
Achelous, a great divinity of Greece
Each and every oracle had its worth
Heavenly nourishment shall increase
Worship sweet water he does release
All at once he lost his daughters
Alas his soul began to crease
His mother conjured gushing waters
Gradually sorrow did decrease
Now Achelous simply flows at peace
