Here's why:
* Victorian era is a broad time frame: It spans from 1837 to 1901. Horse breeding practices evolved during this time, and many different breeds were popular.
* Breed matters: Some breeds are known for being heavier than others. For example, a Shire horse is significantly heavier than a Shetland pony.
* Individual variation: Even within the same breed, horses can vary in size and weight.
To estimate the weight of a Victorian horse, you would need more information:
* Breed: What breed of horse was it?
* Sex: Was it a mare, stallion, or gelding?
* Age: What was its approximate age?
* Size: Was it considered small, medium, or large for its breed?
With this information, you could consult a breed standard or a horse weight calculator to get a more accurate estimate.
