The London Encyclopaedia (1829).
The etymology of farrier is somewhat up for debate, but one explanation is that it is a combination of Latin words when put together literally means blacksmith (Ryan, http://www.horseshoes.com/index.php/educational-index/articles/essays-for-horse-owners/330-a-short-history-of-the-term-qfarrierq). However, farriers were more than blacksmiths, having also to understand horse physiology, veterinarian care, and how to craft a shoe to fit each individual hoof.
In a culture dependent on horses as a primary mode of transportation, the farrier would have been indispensable. Although farriers were established as an official “company” in the 1300s in London, it wasn’t until 1887 that the Company would begin administering tests to tradesmens to verify their skills (http://www.thefarrierguide.com/2015/farrier-history/).
