So that upon a single view and outward observation they may be the Monuments of any of these three Nations: Although the greatest number, not improbably, of the Saxons; who fought many Battels with the Britaines and Danes, and also between their own Nations, and left the proper name of Burrows for these Hills still retained in many of them, as the seven Burrows upon _Salisbury_ Plain, and in many other parts of _England_. But of these and the like Hills there can be no clear and assured decision without an ocular exploration, and subterraneous enquiry by cutting through one of them either directly or crosswise. For so with lesser charge discovery may be made what is under them, and consequently the intention of their erection. For if they were raised for remarkable and eminent Boundaries, then about their bottom will be found the lasting substances of burnt Bones of Beasts, of Ashes, Bricks, Lime or Coals. If Urns be found, they might be erected by the Romans before the term of Urn-burying or custom of burning the dead expired: but if raised by the Romans after that period; Inscriptions, Swords, Shields, and Arms after the Roman mode, may afford a good distinction. But if these Hills were made by Saxons or Danes, discovery may be made from the fashion of their Arms, Bones of their Horses, and other distinguishing substances buried with them. And for such an attempt there wanteth not encouragement. For a like Mount or Burrow was opened in the days of King _Henry_ the Eighth upon _Barham_ Down in _Kent_, by the care of Mr. _Thomas Digges_ and charge of Sir _Christopher Hales_; and a large Urn with Ashes was found under it, as is delivered by _Thomas Twinus De Rebus Albionicis_, a learned Man of that Country, _Sub incredibili Terræ acervo, Urna cinere ossium magnorum fragmentis plena, cùm galeis, clypeis æneis et ferreis rubigine ferè consumptis, inusitatæ magnitudinis, eruta est: sed nulla inscriptio nomen, nullum testimonium tempus, aut fortunam exponebant_: and not very long ago, as _Cambden_[271] delivereth, in one of the Mounts of _Barklow_ Hills in _Essex_, being levelled there were found three Troughs, containing broken Bones, conceived to have been of Danes: and in later time we find, that a Burrow was opened in the Isle of _Man_, wherein fourteen Urns were found with burnt Bones in them; and one more neat than the rest, placed in a Bed of fine white Sand, containing nothing but a few brittle Bones, as having passed the Fire; according to the particular account thereof in the description[272] of the Isle of _Man_. Surely many noble Bones and Ashes have been contented with such hilly Tombs; which neither admitting Ornament, Epitaph or Inscription, may, if Earthquakes spare them, out last all other Monuments. _Suæ sunt Metis metæ._ Obelisks have their term, and Pyramids will tumble, but these mountainous Monuments may stand, and are like to have the same period with the Earth.
