The Mannelli lay claim to be descendants of the great Roman family of the Manlii. They certainly are among the most ancient families of Florence, and in old times were known as the Pontigiani, probably because having built the first wooden Ponte Vecchio they had the right to demand toll, and were the custodians of the bridge. They also bore the names of Piazzegiani and of Capo di Ponte, from living close to the Piazza of Sta. Felicita and on account of the position of their palace, and of their tower which abuts on the bridge and was built about the XIIth century.

Already a powerful family in 1173 when Mannello di Bellondino was created a knight of the Golden Spur for services rendered to his native city, they became yet stronger when his two sons Abate and Rinuccio attained the position of Elders of the Republic. They were Ghibellines, and intermarried with the great family of the Uberti. But several of Abate’s sons went over to the opposite faction, and to the valour of Messer Coppo was attributed the victory of the Guelphs at the battle of S. Jacopo in the Val di Serchio in 1256. He and his brother Mannelino fought against their cousins, sons of Rinuccio, at Montaperti, and had to fly from Florence with the other Guelph nobles. Six years later the Ghibellines were beaten, and when the “Peace of the Cardinal Latino” was proclaimed in 1280, members of the Mannelli family were found in both camps. Among the signatories of the peace was Lapo, son of Messer Coppo, who had fought gallantly at Campaldino and was knighted in 1292. He had many sons, all distinguished soldiers whose names figure in the long list of battles fought during the first half of the XIVth century. His grandson, Amaretto, was deputed to guard the Val d’Elsa against the Pisans. Amaretto declared himself a popolano in 1361, and assumed the name of Pontegiani; sixteen years later he was one of the Buonomini, but being “admonished” by the Captains of the Guelph party he joined in the Ciompi riots and was knighted by the mob in 1380. When the nobles returned to power he was exiled, and to while away time wrote a history of the world. By his wife, Maria Strozzi, he left two sons, Francesco and Raimondo; the elder, to whom the world owes a large debt of gratitude, was probably an ecclesiastic. An intimate friend of Boccaccio, he made a copy of the Decameron which would otherwise have been lost. Boccaccio left his own manuscript by will to Fra Martino of Signa for his life, and then to the monastery of S. Spirito in Florence. It is supposed to have perished either in the fire which destroyed the church in 1471, or more probably in Savonarola’s bonfire of “obscenities and vanities” in which so much that was beautiful and precious went into smoke and ashes. Boccaccio must often have been a guest in the Mannelli palace, and one regrets that his friend Francesco was not endowed with the pen of a Boswell, to have preserved for us the personality of Giovanni Boccaccio. Francesco Mannelli only finished his copy nine years after the death of his friend; it came into the possession of the Medici, but disappeared, and was fortunately discovered and bought by Messer Baccio Baldini, doctor to the Grand Duke Cosimo I. and librarian of the Laurentian library, where it now is. At the end of the manuscript is written: Qui finisce la decima e ultima Giornata del libro chiamato Decameron cognominato Principe Galeotto, Scripto per me Francesco d’Amaretto Mannelli di 13 d’Agosto 1384. Deo sit laus et gloria, in ecternum ad honorem egregi Simacu Spinis et beneplacitum, et mandatum.

Raimondo, his brother, was a sailor, and distinguished himself in an engagement against Spinola, admiral of the fleet of Filippo Visconti, who then held Genoa. The allied fleets of Venice and Florence met the enemy off Rapallo on the 27th August, 1431, but the wind was unfavourable and many of their ships found great difficulty in getting out of Porto Fino. Raimondo, seeing his friends hard pressed, urged on his crew with threats, ran down Spinola’s galley and took him and sixty of his men prisoners. He was shabbily treated by the Venetian admiral in command, who took, not only the honour and glory, but the prisoners and consequently their ransom, from him. Mannelli’s portrait is painted among other seafaring worthies on one of the ceilings in the Pitti palace. Messer Coppo’s posterity died out in the XVIIth century, and the present branch of the family descend from his brother Nerlo, whose son Chele was surnamed Gorget, from his uncomfortable habit of wearing that part of his armour by day and by night. He was a good soldier, and at San Casciano killed with his own hand the leader of a strong body of French troops sent by Henry VII. to raid the Florentine territory. Jacopo Mannelli took a prominent part in the revolt against the Duke of Athens, and was named custodian of the bridge of Sta. Trinita, but one of his descendants, Filippo, a canon of the cathedral, disgraced the name of Mannelli by revealing the deliberations of the Council of the Republic to the enemy. He died by the hand of another priest in 1536.

The old palace and the tower ran great risk of destruction, or at the least of alteration when Vasari made the corridor between the Pitti palace and the Uffizi. “In order to make the corridor straight,” writes Mellini, “it was necessary to pass through the house of the Mannelli by the Ponte Vecchio, at the end of the Via de’ Bardi; so he [Cosimo I.] sent for the owners of the said house and asked if they were courteously inclined to permit him to make the passage. On the plea that it would spoil their house they refused, and he then placed it as we now see on stone brackets, passing by a sharp turn round the outside of the house. But he bore them no rancour, saying that every one was master of his own.”46 Two of the family, Jacopo and his son Ottavio, were made Senators in the XVIIIth century, and the family still own and inhabit the palace and the stern old tower which guards the Ponte Vecchio.
