Generally, while ass and donkey are used interchangeably, a donkey is considered to be a domesticated ass. As the illustrations show, the donkey predominately domesticated and used as a beast of burden. As donkey's have an ability to carry heavy loads over long distances in a reliable and dependable way. Comparatively, horses require more attention and have a tendency to lose focuses and become easily startled (see HMCMS:FA2010.603). Moreover, aside from French drum heads, the illustrations highlight the practical use of donkeys and this is reflective of their significance and role in society. Interestingly, one of the illustrations highlights its use for the Eastern Dervish. The term Dervish refers to a member of a Muslim (specifically Sufi) religious order who has taken vows of poverty and austerity. This reference is incredibly specific when compared to similar plates and uses. Based on this, it can be speculated that this is a reference to the use of donkeys above horses in Africa and Asia.
