This short video shows two Sorraia horses in a carriage driving event in Portugal. The Sorraia is an ancient breed thought to have been influential in the development of the Lusitano horse. The Portuguese breed association page is here. You can find English information here.
It's interesting to see which breeds of horses were widely known in past times. Looking at show programs or books about horse breeds from past decades (or centuries) reveals which breeds were popular or recognized then, and it's often quite different from today.
The map pictured was issued in 1934.
The breeds described are (from bottom center, moving clockwise):
If you like ancient mosaics, I've just discovered a wonderful blog called the Mosaic Art Source Blog! The post on horses in mosaics is not to be missed! They have collected a wonderful set of photos of both modern and ancient mosaics from a variety of sources, all featuring horses.
This site features a detailed description (and photo) of a 5th or 6th century statue of horse and rider found in an old tomb in South Korea. Take a look at the detailed tack and clothing on the statue pictured there. The statue is considered a national treasure.
Dario over at Dario's Caballeros pointed me to Angela Swedberg's blog. Wow! Angela's profession and hobby is restoring and re-creating Plain's Indian beadwork, horse trappings and other ornamented clothing and gear. She does an astonishing job. Her work is stunning. Her blog is full of beautiful photos showing original items and her reproductions. Keep up the amazing work, Angela!
Horses in Russian Art is a fantastic book - one of my favorite horse art books. It is pretty much nothing but pictures. The wide variety of paintings, sculptures, and even old photos include scenes from battle, horses in harness, rural and farm horses, and even a whole set of illustrations of the finest horses at the old stud farms. The art includes a lot from the 19th century, but also some more modern paintings.
It's really neat to see the Russian breeds, traditional tack, and old riding costumes. I'd highly recommend this book for anyone interested in the Russian or old Soviet breeds, historic tack and costumes, or horse art in general.
