31. Ducange, Fam. Byzant. p. 67. On one side, the head of
Valentinian; on the reverse, Boniface with a scourge in one
hand and a palm in the other, standing in a triumphal car,
which is drawn by four horses, or, in another medal, by four
stags; an unlucky emblem ! I should doubt whether another
example can be found of the head of a subject on the reverse
of an Imperial medal. See Science des Medailles, by the Pere
Jobert, tom. i. p. 132-1 50, edit. of 1739, by the Baron de
la Bastie.
