"Stonehenge, at a distance, appeared only a
diminutive object. Standing on so vast an
area as Salisbury Plain, it was lost in the immensity around it. As we approached, it
gained more respect: and we could now trace
a large ditch round the whole, confined within
a gentle mound. But when we arrived on
the spot, it appeared astonishing beyond conception. A train of wondering ideas immediately crowded into the mind. Who brought
these huge masses of rock together ? Whence
were they brought ? For what purpose? By
what machines were they drawn? Or by what
mechanic powers erected?"
