“ From an early period Vertue was ardently devoted to antiquarian research, and by his incessant and conscientious labours in this field he has earned enduring fame. Obtaining the patronage of the Earl of Oxford, Lord Coleraine, and other noblemen of similar tastes, he travelled in their company through many parts of England, visiting the great country houses and other places of interest, and making careful notes and drawings of everything of artistic and antiquarian value that he met with, and his engravings of these subjects are almost as numerous as his portraits. ”
