superbly balanced, suggestive of Greek art in the simplification of form, and yet realistic, without any striving after ideal proportions. The same tendencies are to be noted in the bronze putto at the Bargello.
In 1443 Donatello was invited to Padua to undertake the decoration of the high altar of S. Antonio, but in the period preceding his departure he not only assisted Brunelleschi in the decoration of the sacristy of S. Lorenzo, towards which the bronze doors are his chief contribution, but found time to chisel, or model in wax or terra-cotta, for Cosimo and other private patrons, most of the portrait busts and small reliefs, which are now distributed over the museums of the world. His first work in Padua was the bronze crucifix for the high altar, a work immeasurably superior to the early wooden crucifix at S. Croce, both as regards nobility of expression and subtlety of form. In the very year when Donatello arrived in Padua the famous Condottiere Erasmo de’ Narni, called Gattamelata, had died, and when it was decided to honour his memory with an equestrian statue, it was only natural that this master should be chosen to undertake a task from the difficulties of which all others may well have shrunk—had shrunk, indeed, since classic times. This commission, and the reliefs and figures for the high altar, kept Donatello in Padua for ten years, though during that time he visited Venice (where he carved the wooden “St John” at the Frari) and probably Mantua, Ferrara and Modena. At least, he was in communication with of Borso d’Este of Modena about a project for an equestrian statue, and had to give expert opinion about two equestrian statues at Ferrara. In his workshop in Padua he gathered around him quite a small army of assistants, stone-carvers, metal-workers, painters, gilders and bronze-casters. The Gattamelata was finished and set up in 1453—a work powerful and majestic in its very repose; there is no striving for dramatic effect, no exaggerated muscular action, but the whole thing is dominated by the strong, energetic head, which is modelled with the searching realism of the Zuccone and the Poggio heads. The high altar, for which Donatello executed twenty-two reliefs, seven statues and the crucifix, was completed in 1450, but had subsequently to undergo many changes, in the course of which the original disposition of the sculptures was entirely lost sight of, the present arrangement being due to Camillo Boito (1895). The chief features of the altar are the wonderfully animated and dramatic bronze reliefs, four in number, of the “Miracles of St Anthony.”
With the exception of another visit to Siena in 1457, of which the bronze “St John” in the cathedral is a reminder, Donatello spent the remaining years of his life in Florence. Closely akin to the rugged “St John” at Siena, and therefore probably contemporaneous, is the repulsively ugly, emaciated “Magdalen” at the baptistery in Florence. The dramatic intensity of the “Judith” group in the Loggia de’ Lanzi, which was originally placed in the court of the Medici Palace, marks it as belonging to the post-Paduan period of the master’s life. His last work of importance was the bronze reliefs for the pulpit of S. Lorenzo, commissioned about 1460, and finished after Donatello’s death by his pupil Bertoldo. The reliefs of the “Flagellation” and “Crucifixion” at the Victoria and Albert Museum are typical examples of the master’s style at this closing period of his life. He died on the 13th of December 1466.
As happened subsequently to Velazquez and Frans Hals, Donatello, whose supreme mastery had been acknowledged by Michelangelo, Raphael and the other giants of the late Renaissance, almost sank into oblivion during the 18th and early 19th centuries, and only in comparatively recent times has he been restored to the eminent position which is his due in the history of art. The full power of his genius was only revealed to the world when, at the quincentenary celebration of his birth, the greater part of his life-work was brought together in Florence. The large hall at the Bargello has ever since been devoted to the display of his works, the numerous original bronzes and marbles and terra-cottas being supplemented by casts of works at other places, such as the colossal Gattamelata monument.
Authorities.—Before the date of the Florence exhibition in 1886 the only books on the subject of Donatello—apart from references in general histories of art—were Pastor’s Donatello (Giessen, 1882) and Semper’s Donatello, seine Zeit und seine Schule (Vienna, 1875). Since then the great Florentine sculptor has received attention from many of the leading art writers, though England has only contributed a not very complete record of his life and work by Hope Rea, Donatello (London, 1900), and an excellent critical study by Lord Balcarres, Donatello (London, 1903), besides a translation of A. G. Meyer’s fully illustrated and exhaustive monograph in the Knackfuss series (London, 1904). Other notable books on the subject are:—Eugène Müntz, Donatello (Paris, 1885), and in the series of Les Artistes célèbres (Paris, 1890); Schmarzow, Donatello (Breslau, 1886); Cavalucci, Vita ed opere del Donatello (Milan, 1886); Tschudi, Donatello e la critica moderna (Turin, 1887); Reymond, Donatello (Florence, 1899); and Bode, Florentiner Bildhauer der Renaissance (Donatello als Architekt und Dekorator, Die Madonnenreliefs Donatellos) (Berlin, 1902).

DONATI, GIOVANNI BATTISTA (1826–1873), Italian astronomer, was born at Pisa on the 16th of December 1826. He entered the observatory of Florence as a student in 1852, became assistant to G. B. Amici in 1854, and was appointed in 1864 to succeed him as director. A new observatory at Arcetri near Florence, built under his supervision, was completed in 1872. During the ten years 1854–1864 Donati discovered six comets, one of which, first seen on the 2nd of June 1858, bears his name (see Comet). He observed the total solar eclipse of the 18th of July 1860, at Torreblanca in Spain, and in the same year began experiments in stellar spectroscopy. In 1862 he published a memoir, Intorno alle strie degli spettri stellari, which indicated the feasibility of a physical classification of the stars; and on the 5th of August 1864 discovered the gaseous composition of comets by submitting to prismatic analysis the light of one then visible. An investigation of the great aurora of the 4th of February 1872 led him to refer such phenomena to a distinct branch of science, designated by him “cosmical meteorology”; but he was not destined to prosecute the subject. Attending the International Meteorological Congress of August 1873 at Vienna, he fell ill of cholera, and died a few hours after his arrival at Arcetri, on the 20th of September 1873.

DONATIO MORTIS CAUSA (grant in case of death), in law, a gift of personal property made in contemplation of death and intended either expressly or impliedly to take complete effect only if the donor dies of the illness affecting him at the time of the gift. The conception as well as the name is borrowed from Roman law, and the definition given by Justinian (Inst. ii. 7. 1) applies equally to a donatio mortis causa in Roman and English law. A distinction, however, has arisen between the English and civil codes; by English law delivery either actual or (when from the nature of the thing actual delivery is impossible) constructive is essential, and this delivery must pass not only the possession but the dominion of the thing given; by the civil law, in some cases at least, delivery of possession was not essential (see the judgment of Lord Chancellor Hardwicke in Ward v. Turner, 1751, 2 Ves. sen. 431, where the whole question is exhaustively discussed). A donatio mortis causa stands halfway between a gift inter vivos and a legacy, and has some of the characteristics of each form of disposition. It resembles a legacy in that (1) it is revocable during the donor’s life, (2) it is subject to legacy and estate duty, and (3) it is liable to satisfy debts of the testator in default of other assets. On the other hand, it resembles a gift inter vivos in that it takes effect from delivery; therefore the consent of the executor is not necessary. Anything may be the subject of a donatio mortis causa, the absolute property in which can be made to pass by delivery after the donor’s death either in law or equity; this will cover bankers’ deposit notes, bills of exchange, and notes and cheques of a third person, but not promissory notes and cheques of the donor in favour of the donee, for the donor’s signature is merely an authority for his banker to pay, which is revoked by his death.
