He is best known for his great Glossarium ail Scriptorcs Mftlia' cf Infintw Latinilatis, piiblislicd in three volumes in Paris in 1078, a veritable treasure of industry and erudition. It went through many editions, al- ways with an inereaso of subjeel-matter, and was last published in ten volumes by Favre (Xiort. 18S4S7). and is the standard work on mediæval Latin. Dii Cunjie planned a similar work for mediaeval Greek, and published the Glossarium Mcdiw ct Iii/iiita- (Iracilatii). on a less extensive seale, in Lyons in KiSS, the year of his death. He edited several Byzantine historians, with Latin translations, as I'nulus Siloitiariiis (1670): Zonaras (1G87); yicephoriis Gregoras (published posthumously in 1702): and the Chronicon PaschaJe site Alcxaiidrinum in 1088.

Ducats were first struck by the Byzan- tine emperors in the eleventh century, or, accord- ing to some authorities, a century later, in Sicily. The name is said to have originated from the legend found on early Sicilian pieces, .S'i7 tihi, Christr, dnIiiK. quern til rcf/is, iste Ducat us ("Be intrusted to thee, Christ, this duchy (Ducatus) of which Thou art ruler"). Especially famous were the golden ducats of Venice, known as zccchini or sequins. Later, Holland, the German Empire, Russia, and the States of the north began the striking of ducats. At present there are practically none of these coins in existence, outside of collectors' cabinets. The value of the principal ducats formerly in cir- culation ranged from .'1.40 for the Venetian to $2. .'52 for the Spanish and Hanoverian coin ; the usual value was S2..32. Venice and the Two Sici- lies struck also silver ducats of the value of $0.83 Vol. VI. —32. a|)priiximate!y, and ."spain issued silver ducat-s varying in value from .•?0.90 to $1.10. In .Austria- Hungary gold ducats are still coined, chielly for the purposes of foreign trade, especially in the Levant. (,)uadrup!e ducats also are struck. DUCCIO DI BTJONINSEGNA, ATvTMu', d6 bw.. iu'-n-s;Vny:'i (c. 1200-1320) . An Italian painter, founder of the Sienese school. Little is knovn of his career. He was born in Siena, where he passed most of his life. He was in Florence in 1285, we learn from public documents of the time, and received an order to paint an altar- piece for Santa .Maria Xovella, which he proba- bly never fulfilled. After his return to Siena he appears to have executed a "Majesty," of which there is no record, and in 1308 he began his great work, the high altar in the Duomo. There are records showing this to have been a special order from JIariscotti. master of the work on the cathedral. When the picture was completed in 1310, the entire city celebrated a fete. It was carried, like the famous iladonna of Cimabue, from his studio to the cathe- dral, accompanied by a great procession of citizens and clergj' in gala dress. The picture is fourteen feet long, and seven high; the faces rejuesented are those of the Virgin and Child surrounded by angels, saints, and bishops of the Church. On the reverse is shown in twenty-six compartments the Passion of Christ, with a background of gold. The figures in this series are animated and the groups show dramatic feeling. Like Giotto, with whom he can be compared, Duccio was a reformer and an innovator. Under his brush, the still' Byzan- tine figures took on grace and life, though he departed little from the traditional models. His drawing was correct and dignified; he loved detail and ornament, and he tried to produce soft and pleasing color. In this work Duccio established certain characteristics which came tc be identified with the Siennese school for more than a century. The picture has since been di- vided into several panels, but it remains in the cathedral. There are two Madonnas by Duccio ir. the Academy of Siena, and a good example of his work at Windsor, and in the National Gal- lery in London, both JIadonnas, and figures of saints in the Rambona collection in Cologne.
