Archytas of Tarentum, a celebrated Pythagorean philosopher, who flourished about four hundred years before the Christian era, is indeed said to have constructed a wooden flying pigeon; but, from the imperfect accounts transmitted to us of its machinery, there is every probability that its flight was one of the many deceptions of the magic art which the ancients so well understood and so expertly practiced. The attention of man was much earlier, as well as more earnestly and successfully turned to the art of navigating lakes, rivers, and seas. To gratify his curiosity, or to better his condition, he was prompted to emigrate, or to pass from one place to another, and thus he would tax his ingenuity to discover the means by which he might be enabled to accomplish his journey. To make the atmosphere the medium of transit, would, in the early stages of society, hardly strike the mind at all, or, if it did, it would only strike it as a physical impossibility. Nature has not supplied man with wings, as it has done the fowls of heaven, and to find a locomotive means of transportation through the air was in the infancy of all science absolutely hopeless. But advantage would be early taken of the buoyant property of water, particularly of the sea, which must have been known to mankind from the creation. The canoe and the raft would be first constructed, and, in the course of time, experience would teach men to build vessels of a larger size, to fix the rudder to the stern, to erect the mast, and unfurl the sails. Thus would the art of navigating the ocean advance from step to step, while the art navigating the air remained a mystery, practiced, it may be, by flying demons, and flying witches, and the like ethereal beings of a dark mythology, but an achievement to which ordinary mortals could make no pretensions. Our object in this paper is to give a concise history of aeronautics, commencing at that period when something like an approach was made to the principles upon which the art could be reduced to practice.
