DON JUAN, the member of a distinguished family of Seville, who seduces the daughter of a noble, and when confronted by her father stabs him to death in a duel; he afterwards prepares a feast and invites the stone statue of his victim to partake of it; the stone statue turns up at the least, compels Don Juan to follow him, and delivers him over to the abyss of hell, the depths of which he had qualified himself for by his utter and absolute depravity.

DON QUIXOTE, the title of a world-famous book written by Miguel Cervantes, in satire of the romances of chivalry with which his countrymen were so fascinated; the chief character of which gives title to it, a worthy gentleman of La Mancha, whose head is so turned by reading tales of knight-errantry, that he fancies he is a knight-errant himself, sallies forth in quest of adventures, and encounters them in the most commonplace incidents, one of his most ridiculous extravagancies being his tilting with the windmills, and the overweening regard he has for his Dulcinea del Tobosa.

DONALDSON, JOHN WILLIAM, a philologist, born in London; Fellow of Cambridge and tutor of Trinity College; author of “New Cratylus; or Contributions towards a more Accurate Knowledge of the Greek Language,” a work of great erudition and of value to scholars; contributed also to the philological study of Latin, and wrote a grammar of both languages; he failed when he intruded into the field of biblical criticism (1811-1861).

DONATELLO, a great Italian sculptor, born at Florence, where he was apprenticed to a goldsmith; tried his hand at carving in leisure hours; went to Rome and studied the monuments of ancient art; returned to Florence and executed an “Annunciation,” still preserved in a chapel in Santa Croce, which was followed by marble statues of St. Peter, St. Mark, and St. George, before one of which, that of St. Mark, Michael Angelo exclaimed, “Why do you not speak to me?”; he executed tombs and figures, or groups in bronze as well as marble; his schoolmasters were the sculptors of Greece, and the real was his ultimate model (1383-1460).

DONATI, an Italian astronomer, born at Pisa; discoverer of the comet of 1858, called Donati’s comet (1826-1873).

DONATISTS, a sect in N. Africa, founded by Donatus, bishop of Carthage, in the 4th century, that separated from the rest of the Church and formed itself into an exclusive community, with bishops and congregations of its own, on the ground that no one was entitled to be a member of Christ’s body, or an overseer of Christ’s flock, who was not of divine election, and that in the face of an attempt, backed by the Emperor Constantine, to thrust a bishop on the Church at Carthage, consecrated by an authority that had betrayed and sold the Church to the world; the members of it were subject to cruel persecutions in which they gloried, and were annihilated by the Saracens in the 7th century.

DONATUS, a Latin grammarian and rhetorician of the 4th century, the teacher of St. Jerome; the author of treatises in grammar known as Donats, and, along with the sacred Scriptures, the earliest examples of printing by means of letters cut on wooden blocks, and so appreciated as elementary treatises that they gave name to treatises of the kind on any subject; he wrote also scholia to the plays of Terence.
