Engraving with etching of Theodo IV, Duke of Bavaria. Half length with plumed cap, doublet, and embroidered robes, holding a dagger in right hand. Within an oval border bearing German inscription, and with an allegorical design of a dagger within a cartouche below.

Theodo IV was an early Duke of Bavaria, one of the Dukes who supposedly ruled between Garibald II (r.610-25) and Grimoald (r.715-25).

From a series of 56 portraits of the Dukes of Bavaria, from the early rulers of the sixth century to Ferdinand Maria, Elector of Bavaria (ruled 1651-79). The portraits were published as plates to Andreas Brunner's Schau-Plaz Bayerischer Helden. Das ist Auführlicher Entwurff aller Bayerischen Herzoge (1681). The portraits were copied after an earlier series, engraved by Wolfgang Kilian, which originally appeared in the 1637 edition of Excvbiae Tvtelares Serenissimi Principis Ferdinandi Mariae Francisci Ignatii VVolfgangi, Vtr. Boiar. D. Com. Pal. Rheni, also by Brunner.
