Of all the historic highways of England, the story of the old Road to Dover is the most difficult to tell. No other road in all Christendom (or Pagandom either, for that matter) has so long and continuous a history, nor one so crowded in every age with incident and associations. The writer, therefore, who has the telling of that story to accomplish is weighted with a heavy sense of responsibility, and though (like a village boy marching fearfully through a midnight churchyard) he whistles to keep his courage warm, yet, for all his outward show of indifference, he keeps an awed glance upon the shadows that beset his path, and is prepared to take to his heels at any moment.And see what portentous shadows crowd the long reaches of the Dover Road, and demand attention! Cæsar's presence haunts the weird plateau of Barham Downs, and the alert imagination hears the tramp of the legionaries along Watling Street on moonlit nights. Shades of Britons, Saxons, Danes, and Normans people the streets of the old towns through which the highway takes its course, or crowd in warlike array upon the hillsides. Kings and queens, nobles, saints of different degrees of sanctity, great blackguards of every degree of blackguardism, and ecclesiastics holy, haughty, proud, or pitiful, rise up before one and terrify with thoughts of the space the record of their doings would occupy; in fine, the wraiths and phantoms of nigh upon two thousand years combine to intimidate the historian.
