Tolfa
Tolfa is a town and '' comune'' of the Metropolitan City of Rome, in the Lazio region of central Italy; it lies to the ENE of Civitavecchia by road. It is the main center in the Monti della Tolfa, an extinct volcanic group between Civitavecchia and the Lake of Bracciano. History A town of medieval origin in the orbit of Viterbo, it was assumed into the Papal States and granted first to the Capocci family, and then to the Roman nobles Ludovico and Pietro Frangipani who walled the community. Tolfa achieved sudden importance following the discovery there in 1461 of large deposits of alunite, the source of alum, with the result that direct control was assumed, after some confrontations with the Frangipani, by the Camera Apostolica. Alum was an essential mordant in the textile industry, which was central to the Late Medieval and Early Modern Italian economy. Previously, the only supplies of alum were imported from the East, from sources controlled by the Ottoman Turks, through Ve ...

Monti Della Tolfa
The Monti della Tolfa (or Tolfa Mountains) are a volcanic group in the Anti-Apennines of the northern part of the Lazio region of Central Italy. They are bounded by the Tyrrhenian Sea coast to the west, by the Monti Sabatini to the east, and by the Monti Cimini and the Mignone river to the north. Tolfa and Allumiere are the principal towns. The highest peak is the Monte Maggiore (633 m above sea level). The Monti della Tolfa consists mostly of trachytes formed during the Eocene and the early Pleistocene. The mountains are an important source of alunite, from which alum An alum () is a type of chemical compound, usually a hydrated double sulfate salt of aluminium with the general formula , where is a monovalent cation such as potassium or ammonium.

Alunite
Alunite is a hydroxylated aluminium potassium sulfate mineral, formula K Al3( S O4)2(O H)6. It was first observed in the 15th century at Tolfa, near Rome, where it was mined for the manufacture of alum. First called ''aluminilite'' by J.C. Delamétherie in 1797, this name was contracted by François Beudant three decades later to alunite. Alunite crystals morphologically are rhombohedron, rhombohedra with interfacial angles of 90° 50', causing them to resemble cubes. Crystal symmetry is trigonal. Minute glistening crystals have also been found loose in cavities in altered rhyolite. Alunite varies in color from white to yellow gray. The hardness on the Mohs scale is 4 and the specific gravity is between 2.6 and 2.8. It is insoluble in water or weak acids, but soluble in sulfuric acid. Sodium can substitute for potassium in the mineral, and when the sodium content is high, is called natroalunite. Alunite is an analog of jarosite, where aluminium replaces Fe3+. Aluni ...

Agostino Chigi
Agostino Andrea Chigi (29 November 1466 – April 11, 1520) was an Italian banker and patron of the Renaissance. Born in Siena, he was the son of the prominent banker Mariano Chigi, a member of the ancient and illustrious Chigi family. He moved to Rome around 1487, collaborating with his father. The heir of a rich fund of capital, and enriched further after lending huge amounts of money to Pope Alexander VI (and to other rulers of the time as well), he strayed from common mercantile practice by obtaining lucrative monopolies like the salt monopoly of the Papal States and the Kingdom of Naples, as well as that of the alum excavated in Tolfa, Agnato and Ischia di Castro. Alum was an essential mordant in the textile industry. After the death of the Borgia pope Alexander VI and his short-lived Sienese successor Pius III Piccolomini, he helped Pope Julius II in the expenses attendant upon his election. The latter rewarded him, linking Chigi to the della Rovere family, and cre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medici
The House of Medici ( , ) was an Italian banking family and political dynasty that first began to gather prominence under Cosimo de' Medici, in the Republic of Florence during the first half of the 15th century. The family originated in the Mugello region of Tuscany, and prospered gradually until it was able to fund the Medici Bank. This bank was the largest in Europe during the 15th century and facilitated the Medicis' rise to political power in Florence, although they officially remained citizens rather than monarchs until the 16th century. The Medici produced four popes of the Catholic Church—Pope Leo X (1513–1521), Pope Clement VII (1523–1534), Pope Pius IV (1559–1565) and Pope Leo XI (1605)—and two queens of France— Catherine de' Medici (1547–1559) and Marie de' Medici (1600–1610). In 1532, the family acquired the hereditary title Duke of Florence. In 1569, the duchy was elevated to the Grand Duchy of Tuscany after territorial expansion. The Medici ru ...

Allumiere
Allumiere ( Romanesco: ) is a '' comune'' (municipality) in the Metropolitan City of Rome in the Italian region Latium, located about northwest of Rome. Allumiere is traditionally divided into the ''contrade'' of Burò, Ghetto, La Bianca, Nona, Polveriera, and Sant'Antonio. History Although evidence of human settlements in the local area date back to the Neolithic age, the origins of the modern town of Allumiere are relatively recent. Allumiere was founded in the late 15th century to house the workers and the administrators of the important mines of alunite of the nearby Monti della Tolfa range. The exploitation lasted until 1941. The mines in question were found shortly after the fall of the Eastern Roman Empire (1453). Before that date, the State of the Church used to buy alunite from there, but following the Turkish conquest, they had to find alternatives.

Pope Pius II
Pope Pius II ( la, Pius PP. II, it, Pio II), born Enea Silvio Bartolomeo Piccolomini ( la, Aeneas Silvius Bartholomeus, links=no; 18 October 1405 – 14 August 1464), was head of the Catholic Church and ruler of the Papal States from 19 August 1458 to his death in August 1464. He was born at Corsignano in the Sienese territory of a noble but impoverished family. He was a Renaissance humanist, famous as an author in Latin before he became pope. His longest and most enduring work is the story of his life, the ''Commentaries'', which is the only revealed autobiography ever to have been written by a reigning pope. This was only published in 1584. Early life Aeneas was born to Silvio, a soldier and member of the House of Piccolomini, and Vittoria Forteguerri, who had 18 children including several twins, though most died at a young age.

Lake Of Bracciano
Lake Bracciano ( it, Lago di Bracciano) is a lake of volcanic origin in the Italian region of Lazio, northwest of Rome. It is the second largest lake in the region (second only to Lake Bolsena) and one of the major lakes of Italy. It has a circular perimeter of approximately . Its inflow is from precipitation runoff and percolation, and from underground springs, and its outflow is the Arrone. The lake owes its origin to intense volcanic and tectonic activity from 600,000 to 40,000 years before the present, which created many small volcanoes in the ''Sabatino'' territory. The main magma chamber was situated under the present lake of Bracciano. Its collapse created the depressed area now occupied by the lake, which is not a crater lake. Some small craters and calderas are still recognisable around the lake and in the immediate vicinity (Martignano, Baccano, Sacrofano). Three towns border the lake, Bracciano, Anguillara Sabazia and Trevignano Romano. The lake is an importan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Council Of Mantua (1459)
The Council of Mantua of 1459, or Congress of Mantua, was a religious meeting convoked by Pope Pius II, who had been elected to the Papacy in the previous year and was engaged in planning war against the Ottoman Turks, who had taken Constantinople in 1453. His call went out to the rulers of Europe, in an agonized plea to turn from internecine warfare to face Christendom's common enemy. Process of the Council of 1459 Pius entered Mantua on 27 May; his long progress to the place of assembly resembled a triumphal procession. He opened the council on 1 June and waited in Mantua as the guest of Ludovico III Gonzaga until September for the various representatives to assemble. On 26 September he called for a new crusade against the Ottomans. The refugee Cardinal Bessarion and Cardinal Juan de Torquemada were in attendance. The Duke of Burgundy was represented at the Council by the duke of Clèves, who brought in his train the young Burgundian cleric Ferry de Clugny. The humanist Isott ...
