The senmurv is an ancient Persian monster with the front half of a dog and the wings and rear body of a bird. It dates from 7th Century legends [Ernst and Johanna Lehner, A Fantastic Bestiary], but no examples have been found in period armory. As a motif from outside Europe, the use of the senmurv is a step from period practice.
The senmurv has its forelegs extended, and wings elevated and addorsed, by Society default. See also simurgh.
