Weeks five and six for Claudius introduced blinkers (blinders -winkers etc) and eventually his four-wheel marathon wagon. Going from a two wheeled vehicle to a double axle is a big deal. A horse can easily jack knife a four wheeled vehicle if he doesn't have patience to stand. If a horse is reluctant to pass through a puddle it can also make for a rough ride. Claudius is off to a good start. I look forward to bringing him out into the real world.
