The last half century has shown great advance in historical knowledge; libraries and manuscripts long inaccessible have been opened to scholars, and the spirit of investigation has made known many secrets of the past, brought many hidden things to light. Buried cities have been explored and forced to reveal their secrets; lost modes of writing have been deciphered, and olden myths placed upon historic foundations. India is opening her stores of ancient literature; Egypt, so wise and so famous, of which it was anciently said: “If it does not find a man mad it leaves him mad,” has revealed her secrets; hieroglyph-inscribed temples, obelisks and tombs have been interpreted; papyri buried 4,000 and more years in the folds of bandage-enveloped mummies have given their secrets to the world. The brick libraries of Assyria have been unearthed, and the lost civilization of Babylonia and Chaldea imparted to mankind. The strange Zunis have found an interpreter; the ancient Aztec language its Champollion, and the mysteries of even our western continent are becoming unveiled. Darkest Africa has opened to the light; the colossal images of Easter Island hint at their origin; while the new science of philology unfolds to us the history of peoples so completely lost that no other monument of their past remains. We are now informed as to the condition of early peoples, their laws, customs, habits, religion, comprising order and rank in the state, the rules of descent, name, property, the circumstances of family life, the position of mother, father, children, their temples and priestly orders; all these have been investigated and a new historic basis has been discovered. Never has research been so thorough or long-lost knowledge so fully given to the world.
