Attempted translation, reading TVRCA:
Under this bridge the hidden moon surrendered to the sun. 1686
The Turk yielded to Austrian arms while Charles II was
king by the grace of God.
Under what bridge?
The moon must equal the crescent, the Turkish enemy, but why hidden?
Does the sun mean Charles II,
Austria, or the
West generally?
Why name Charles II, Hapsburg
king of
Spain, 1665-1705, rather than Leopold VI, Archduke of
Austria, 1665-1705?
