Crested aloof, and carbuncle his eyes.”

John Norton,[758] an alchemist in the reign of Edward IV., wrote a poem entitled the “Ordinal,” or a manual of the chemical art. One of his projects, we are told, was a bridge of gold over the Thames, crowned with pinnacles of gold, which, being studded with carbuncles, would diffuse a blaze of light in the dark. Among the other references to it given by Shakespeare may be mentioned one in “Henry VIII.” (ii. 3), where the Princess Elizabeth is spoken of as

“a gem
To lighten all this isle.”

And Hamlet (ii. 2) uses the phrase, “With eyes like carbuncles.”
