FROM THE FOREWORD: “It is altogether fitting that the discoveries described in this book were made by an astronomer affiliated with the Smithsonian Astrophysical Observatory. Samuel P. Langley, third secretary of the Smithsonian Institution and founder of its Astrophysical Observatory, was the first maior scientist to recognize the possible astronomic importance of the "rude, enormous monoliths" of Salisbury Plain. In his book The New Astronomy he wrote, "Most great national observatories, like Greenwich or Washington, are the perfected development of that kind of astronomy of which the builders of Stonehenge represent the infancy. Those primitive men could know where the sun would rise on a certain day, and make their observation of its place . .. without knowing anything of its physical nature." By "that kind of astronomy" he meant classical positional observation, the study of the motions rather than the structurest the "where" rather than the "what" —of beavenly bodies. His "new astronomy" was what we now call astrophysics. Langleywrote that in 1889,b y happy coincidence the same year in which construction was begun on the Smithsonian Astrophysical Observatory. He would have been pleased to know that just seventy-five years after he made his extraordinarily wise evaluation a worker in the observatory which he founded would play a part in establishing the great astronomical signiticance of Stonehenge.
