agreeable of pleasures; but his profound studies rendered expedient for him the quiet of a single life.” Swedenborg seems to have had much intercourse with the King. In one of his letters, he says: “I found his Majesty very gracious to me; more so than I could expect. This is a good omen for the future. Every day I laid mathematical subjects before his Majesty, who allowed everything to please him. When the eclipse took place, I had his Majesty out to see it, and we reasoned much thereupon. He again spoke of my ‘Dædalus,’ and remarked upon my not continuing it; for which I pleaded want of means. This he does not like to hear of; so I hope to have some assistance shortly.” But assistance did not come, and “Dædalus” went the way of many such undertakings. Talking of mathematics one day, Charles remarked that “he who knew nothing of mathematics, did not deserve to be considered a rational man;” a sentiment which Swedenborg thought “truly worthy of a king.”[1] Charles XII. was now engaged in the siege of Frederickshall, and Swedenborg’s aid was called in. He very ingeniously planned rolling machines, by which two galleys, five large boats, and a sloop, were conveyed from Stromstadt to Iderfjol, overland; a distance of fourteen miles. Under cover of these vessels, Charles was enabled to transport his heavy artillery under the very walls of Frederickshall; but it availed little, for at the siege of this town, on November 30, 1718, (old style,) this inveterate warrior received the fatal blow which ended his troublous and eventful career. He was struck in the head with a cannon ball, and though death must have been instantaneous, he was found with his right hand firmly grasping the handle of his sword; so prompt was he to put himself in an attitude of defence. “His fall was destined to a barren strand, A petty fortress and a dubious hand; He left a name at which the world grew pale, To point a moral or adorn a tale.” In 1719 the Swedberg family were ennobled by Queen Ulrica Eleonora, and Swedenborg from that time took his place with the nobles of the equestrian order, in the triennial Assemblies of the States. This distinction conferred little else than a change of name. He was neither a Count nor a Baron, as has very commonly been supposed. Emanuel Swedenborg was rapidly winning for himself the name of a deep thinker and a ready writer. In 1717 he published “An Introduction to Algebra,” under the title of “The Art of the Rules.” It was highly praised for its clearness, and the order and force of its examples. The first portion of the work, however, was all that was published. The second, containing the first account given in Sweden of the differential and integral calculus, still remains in MS. His second publication this year was, “Attempts to find the Longitude of Places by Lunar Observations.” Both works were written in Swedish.
