Mirror with Aizen Myōō, turtle, and cranes, late 13th - early 14th century, Unknown Japanese, 3/8 × 4 1/2 × 4 1/2 in. (0.95 × 11.43 × 11.43 cm), Gilt bronze, Japan, 13th-14th century, Aizen Myōō, is one of the Wisdom Kings, fierce spirits associated with esoteric Buddhism. Although his name means 'Wisdom King, Imbued with Love,' a reflection of the love he holds for the Buddha and the love he is shown in return, Aizen Myōō is actually a manifestation of the wrathful aspect of Dainichi, the cosmic Buddha. As such, he has multiple heads and arms and carries a bow and arrow. In this bronze mirror, originally used in esoteric Buddhist ritual, he appears alongside auspicious cranes and turtles.
