How rare were mules in ancient Greece?

Mules were relatively uncommon in ancient Greece compared to horses and donkeys. While they were valued for their strength and endurance, especially in agriculture and transportation, their breeding was less widespread due to the specific conditions required for their production. Mules are hybrids of male donkeys and female horses, which limited their numbers since their breeding depended on the availability of both parent species. Overall, while not extremely rare, mules were not the most common draft animals in ancient Greek society.
