In the “Memoir of John Aubrey”, published by the Wiltshire Topographical Society in 1845, I expressed a wish that the “NATURAL HISTORY of WILTSHIRE”, the most important of that author’s unpublished manuscripts, might be printed by the Society, as a companion volume to that Memoir, which it is especially calculated to illustrate. The work referred to had been then suggested to the Council of the Society by George Poulett Scrope, Esq. M.P., as desirable for publication. They concurred with him in that opinion; and shortly afterwards, through the kind intervention of the Marquess of Northampton, an application was made to the Council of the Royal Society for permission to have a transcript made for publication from the copy of the “Natural History of Wiltshire” in their possession. The required permission was readily accorded; and had not the printing been delayed by my own serious illness during the last winter, and urgent occupations since, it would have been completed some months ago. When the present volume was first announced, it was intended to print the whole of Aubrey’s manuscript; but after mature deliberation it has been thought more desirable to select only such passages as directly or indirectly apply to the county of Wilts, or which comprise information really useful or interesting in itself, or curious as illustrating the state of literature and science at the time when they were written. Before the general reader can duly understand and appreciate the contents of the present volume it is necessary that he should have some knowledge of the manners, customs, and literature of the age when it was written, and with the lucubrations of honest, but “magotie-headed” John Aubrey, as he is termed by Anthony a Wood. Although I have already endeavoured to portray his mental and personal characteristics, and have carefully marked many of his merits, eccentricities, and foibles, I find, from a more careful examination of his “Natural History of Wiltshire” than I had previously devoted to it, many anecdotes, peculiarities, opinions, and traits, which, whilst they serve to mark the character of the man, afford also interesting memorials of his times. If that age be compared and contrasted with the present, the difference cannot fail to make us exult in living, breathing, and acting in a region of intellect and freedom, which is all sunshine and happiness, opposed to the gloom and illiteracy which darkened the days of Aubrey. Even Harvey, Wren, Flamsteed, and Newton, his contemporaries and friends, were slaves and victims to the superstition and fanaticism of their age.
