And the algebraists or arithmeticians of the 16th century, such as Luca Pacioli (Lucas de Borgo), Geronimo or Girolamo Cardano (1501-1576), and Niccola Tartaglia (1506-1559), had used geometrical constructions to throw light on the solution of particular equations.
Luca Jacopo Adeodato Giovanni (1231 and 1235).
The chief signed works by Jacopo the younger and his brother Luca are at Anagni and Subiaco.
The study of Church history was next encouraged, and in August 1883 the pope addressed a letter to Cardinals de Luca, Pitra and HergenrOther, in which he made the remarkable concession that the Vatican archives and library might be placed at the disposal of persons qualified to compile manuals of history.
As for the influence he exercised on posterity, it is enough to say that Luca Pacioli, about 1500, in his celebrated Summa, leans so exclusively to Leonardo's works (at that time known in manuscript only) that he frankly acknowledges his dependence on them, and states that wherever no other author is quoted all belongs to Leonardus Pisanus.
Of the artistic treasures with which the Escorial was gradually enriched, it is sufficient to mention the frescoes of Peregrin or Pellagrino Tibaldi, Luis de Carbajal, Bartolommeo Carducci or Carducho, and Luca Giordano, and the pictures of Titian, Tintoretto and Velasquez.
Luca, on the south-west of the town (938 ft.).
(The root jabara is also met with in the word algebrista, which means a " bone-setter," and is still in common use in Spain.) The same derivation is given by Lucas Paciolus (Luca Pacioli), who reproduces the phrase in the transliterated form alghebra e almucabala, and ascribes the invention of the art to the Arabians.
Various plots against him were hatched, the anti Medicean faction being called the Del Poggio party because the house of its leader Luca Pitti was on a hill, while the Mediceans were called the Del Piano party because Piero's house was in the town below; the other opposition leaders were Dietisalvi Neroni and Agnolo Acciaiuoli.
The cathedral, originally a Tuscan Romanesque building of the 11th-12th centuries, is now a fine Renaissance basilica restored in the 18th century, containing some paintings by Luca Signorelli, a native of the place.

In 56 B.e., at the conference of Luca (Lucca), Caesar, Pompey and Crassus had renewed their agreement, and Caesar's Break-up command in Gaul, which would have expired on the of thak-up ist of March 54 B.e., was renewed, probably for five Coalition.

Spirito are two paintings by Luca Signorelli, the "Crucifixion" and the "Day of Pentecost," originally intended for a processional banner.
It is on the site of the Roman Pistoriae, which is hardly mentioned in ancient times, except for the destruction of Catiline's forces and the slaughter of their leader near it in 62 B.C., and as a station on the road between Florentia and Luca; and earlier still by Plautus, but only with jesting allusion to the similarity of the name to the word pistor (baker).
Within is a beautiful group of the Visitation by Luca della Robbia.
The reliefs consist of a series of groups representing the Seven Works of Mercy and other figures; these were executed by Giovanni Della Robbia between 1514 and 1525, and, though not equal to the best work of Luca and Andrea, are yet very fine in conception and modelling, and extremely rich in their general decorative effect.

Looking on to the piazza is the fine Palazzo Marino, the seat of the municipality since 1861; it was built by Galeazzo Alessi in 1558, to whom the side façade and the court are due, but was not completed until 1890, when the main facade was erected by Luca Beltrami.
Six miles to the south is the large Benedictine monastery of Monte Oliveto Maggiore, founded in 1320, famous for the frescoes by Luca Signorelli (1497-1498) and Antonio Bazzi, called Sodoma (1505), in the cloister, illustrating scenes from the legend of St Benedict; the latter master's work is perhaps nowhere better represented than here.
This brought about the conference of Luca (Lucca).

LUCCA (anc. Luca), a town and archiepiscopal see of Tuscany, Italy, capital of the province of Lucca, 13 m.
The ancient Luca, commanding the valley of the Serchio, is first mentioned as the place to which Sempronius retired in 218 B.
It must have become a municipium by the lex Julia of 90 B.e., and it was here that Julius Caesar in 56 B.C. held his famous conference with Pompey and Crassus, Luca then being still in Liguria, not in Etruria.
Though plundered and deprived of part of its territory by Odoacer, Luca appears as an important city and fortress at the time of Narses, who besieged it for three months in A.D.
And governed by his vicar, Lucca managed, at first as a demo ' Some confusion has arisen owing to the similarity of the names Luca and Luna; the theory of E.
It was separate from Italy proper, the Aesis first and then the Rubicon being the boundary on the east, and the Arnus the boundary on the west, so that, for example, Luca remained outside the boundaries of Italy proper, even in 89 B.C. Romanization had, however, progressed considerably, the foundation of colonies and the construction of roads had gone on during the 2nd century, and the whole district as far as the Padus was given the Roman franchise in 89 B.C., while the Transpadanes received Latin rights, and were fully enfranchised forty years later.
Dating from the 14th century, and restored by Fonsega in the 17th, it is a building of extraordinary richness of decoration, with paintings and sculpture by Guido Reni, Lanfranco, Caravaggio, D'Arpino, Solimene, Luca Giordano and notably a " Descent from the Cross " by Ribera, conconsidered the finest work of this master.
He had formed a new and close friendship with Luca Pacioli of Borgo San Sepolcro, the great mathematician, whose Summa de aritmetica, geometrica, &c., he had eagerly bought at Pavia on its first appearance, and who arrived at the Court of Milan about the moment of the completion of the "Cenacolo."
When, in the last decade of the 19th century, works of thorough architectural investigation and repair were undertaken in that building under the superintendence of Professor Luca Beltrami, a devoted foreign student, Dr Paul Muller-Walde, obtained leave to scrape for traces of Leonardo's handiwork beneath the replastered and whitewashed walls and ceilings of chambers that might be identified with these.
In December he left Milan with his friend Luca Pacioli, having first sent some of his modest savings to Florence for investment.
He had been much helped by his opportunities of intercourse with the great architects, engineers and mathematicians who frequented the court of Milan - Bramante, Alberghetti, Andrea di Ferrara, Pietro Monti, Fazio Cardano and, above all, Luca Pacioli.
To return to the master: when he and Luca Pacioli left Milan in December 1499, their destination was Venice.
There is some doubt on the point; but a contemporary and intimate friend, Luca Pacioli, speaks of his "ineffable left hand"; all the best of his drawings are shaded downward from left to right, which would be the readiest way for a left-handed man; and his habitual eccentric practice of writing from right to left is much more likely to have been due to natural left-handedness than to any desire of mystery or concealment.
It is indeed doubtful whether Leonardo himself ever completed the MS. treatise (or treatises) on painting and kindred subjects mentioned by Fra Luca Pacioli and by Vasari, and probable that the form and order, and perhaps some of the substance, of the Trattato as we have it was due to compilers and not to the master himself.

But beyond Florentia, between Luca (Lucca) and Luna, we find another Forum Clodii, and the Antonine Itinerary gives the route from Luca to Rome as being by the Via Clodia - wrongly as regards the portion from Florentia southwards, but perhaps rightly as regards that from Luca to Florentia.
In that case the Clodius whose name the road bears, possibly C. Clodius Vestalis (c. 43 B.C.), was responsible for the construction of the first portion and of that from Florentia to Luca (and Luna), and the founder of the two Fora Clodii.
