In order to collect taxes for the king mesta kept track of the various herds of animals.
为了给国王收税,mesta负责跟踪记录许多种类的动物。
The reason the group was called mesta was because they took their name from Latin and a phrase animalia mixta.
mesta这一名称来自拉丁语词组“混合物种(animalia mixta)”。
Wild horses such as these began to be called mestengo due to their association with the mesta but the meaning of mestengo was “stray” or “having no master.”
