A surname of Dionysus, which he derived either from Eleuther, or the Boeotian town of Eleutherae; but it may also be regarded as equivalent to the Latin Liber, and thus describes Dionysus as the deliverer of man from care and sorrow. (Paus. i. 20. § 2, 38. § 8; Plut Quaest. Rom. 101.) The form Eleutherius is certainly used in the sense of the deliverer, and occurs also as the surname of Zeus. (Plut Sylmpos. vii. in fin.; Pind Ol. xii. 1; Strab. ix. p. 412; Tacit Ann. xv. 64.)
