Sinopsis

Excerpt from A Calendar of Invention and Discovery

The scholar mourns and antiquity weeps over the wreck of ancient learning and art - the philosopher regrets that sufficient of both has not been preserved to elucidate interesting discoveries, which history has mentioned; nor to prove that those principles of science, upon which the action of their machines depended, were understood. The mechanic seeks in vain the processes by which his predecessors in remote ages worked the hardest granite without iron, transported it in masses that astound -ud used them in the erection of stupendous buildings, apparently with the facili-t that modern workmen lay bricks or raise lintels 0 doors. We are ignorant of their modes of working metals. Of their alloy which rivaled steel in hardness, of their furnaces, crucibles, and moulds; or of the details of forming the ennobling statue. Unfortunately learned men of old deemed it a part of wisdom to conceal from the vulgar all discoveries of science. They wrapped them in mystical figures that the people might not apprehend them.
