BONONIA (mod. Bologna), the chief town of ancient Aemilia (see [Aemilia, Via]), in Italy. It was said by classical writers to be of Etruscan origin, and to have been founded, under the name Felsina, from Perusia by Aucnus or Ocnus. Excavations of recent years have, however, led to the discovery of some 600 ancient Italic (Ligurian?) huts, and of cemeteries of the same and the succeeding (Umbrian) periods (800-600? B.C.), of which the latter immediately preceded the Etruscan civilization (c. 600-400 B.C.). An extensive Etruscan necropolis, too, was discovered on the site of the modern cemetery (A. Zannoni, Scavi della Certosa, Bologna, 1876), and others in the public garden and on the Arnoaldi Veli property (Notizie degli Scavi, indice 1876-1900, s.v. “Bologna”). In 196 B.C., when the town first appears in history, it was already in the possession of the Boii, and had probably by this time changed its name, and in 189 B.C. it became a Roman colony. After the conquest of the mountain tribes, its importance was assured by its position on the Via Aemilia, by which it was connected in 187 B.C. with Ariminum and Placentia, and on the road, constructed in the same year, to Arretium; while another road was made, perhaps in 175 B.C., to Aquilelia. It thus became the centre of the road system of north Italy. In 90 B.C. it acquired Roman citizenship. In 43 B.C. it was used as his base of operations against Decius Brutus by Mark Antony, who settled colonists here; Augustus added others later, constructing a new aqueduct from the Letta, a tributary of the Rhenus, which was restored to use in 1881 (G. Gozzadini in Notizie degli Scavi, 1881, 162). After a fire in A.D. 53 the emperor Claudius made a subvention of 10 million sesterces (£1,087,500). Bononia seems, in fact, to have been one of the most important cities of ancient Italy, as Bologna is of modern Italy. It was able to resist Alaric in 410 and to preserve its existence during the general ruin. It afterwards belonged to the Greek exarchate of Ravenna. Of remains of the Roman period, however, there are none above ground, though various discoveries have been made from time to time within the city walls, the modern streets corresponding more or less, as it seems, with the ancient lines. Remains of the bridge of the Via Aemilia over the Rhenus have also been found— consisting of parts of the parapets on each side, in brick-faced concrete which belong to a restoration, the original construction (probably by Augustus in 2 B.C.) having been in blocks of Veronese red marble—and also of a massive protecting wall slightly above it, of late date, in the construction of which a large number of Roman tombstones were used. The bed of the river was found to have risen at least 20 ft. since the collapse of this bridge (about A.D. 1000), the total length of which must have been about 650 ft. and the width between the parapets 38½ ft.

BONPLAND, AIMÉ JACQUES ALEXANDRE (1773-1858), French traveller and botanist, whose real name was Goujand, was born at La Rochelle on the 22nd of August 1773. After serving as a surgeon in the French army and studying under J.N. Corvisart at Paris, he accompanied A. von Humboldt during five years of travel in Mexico, Colombia and the districts bordering on the Orinoco and Amazon. In these explorations he collected and classified about 6000 plants till then mostly unknown in Europe, which he afterwards described in Plantes équinoxiales, &c. (Paris, 1808-1816). On returning to Paris he received a pension and the superintendence of the gardens at Malmaison, and published Monographie des Mélastomées (1806), and Description des plantes rares de Navarre (1813). In 1816 he set out, taking with him various European plants, for Buenos Aires, where he was elected professor of natural history, an office which he soon quitted in order to explore central South America. While journeying to Bolivia he was arrested in 1821, by command of Dr Francia, the dictator of Paraguay, who detained him until 1831. On regaining liberty he resided at San Borga in the province of Corrientes, until his removal in 1853 to Santa Anna, where he died on the 4th of May 1858.
BONSTETTEN, CHARLES VICTOR DE (1745-1832), Swiss writer, an excellent type of a liberal patrician, more French than Swiss, and a good representative of the Gallicized Bern of the 18th century. By birth a member of one of the great patrician families of Bern, he was educated in his native town, at Yverdon, and (1763-1766) at Geneva, where he came under the influence of Rousseau and of Charles Bonnet, and imbibed liberal sentiments. Recalled to Bern by his father, he was soon sent to Leiden, and then visited (1769) England, where he became a friend of the poet Gray. After his father’s death (1770) he made a long journey in Italy, and on his return to Bern (1774) entered political life, for which he was unfitted by reason of his liberal ideas, which led him to patronize and encourage Johannes Müller, the future Swiss historian. In 1779 he was named the Bernese bailiff of Saanen or Gessenay (here he wrote his Lettres pastorales sur une contrée de la Suisse, published in German in 1781), and in 1787 was transferred in a similar capacity to Nyon, from which post he had to retire after taking part (1791) in a festival to celebrate the destruction of the Bastille. From 1795 to 1797 he governed (for the Swiss Confederation) the Italian-speaking districts of Lugano, Locarno, Mendrisio and Val Maggia, of which he published (1797) a pleasing description, and into which he is said to have introduced the cultivation of the potato. The French revolution of 1798 in Switzerland drove him again into private life. He spent the years 1798 to 1801 in Denmark, with his friend Fredirika Brun, and then settled down in 1803 in Geneva for the rest of his life. There he enjoyed the society of many distinguished persons, among whom was (1809-1817) Madame de Staël. It was during this period that he published his most celebrated work, L’Homme du midi et l’homme du nord (1824), a study of the influence of climate on different nations, the north being exalted at the expense of the south. Among his other works are the Recherches sur la nature et les lois de l’imagination (1807), and the Études de l’homme, ou Recherches sur les facultés de penser et de sentir (1821), but he was better as an observer than as a philosopher.
