In page Walter Scott:

"

As a result of his early polio infection, Scott had a pronounced limp. He was described in 1820 as "tall, well formed (except for one ankle and foot which made him walk lamely), neither fat nor thin, with forehead very high, nose short, upper lip long and face rather fleshy, complexion fresh and clear, eyes very blue, shrewd and penetrating, with hair now silvery white".[1] Although a determined walker, he experienced greater freedom of movement on horseback.[citation needed]
