Stefano Bonsignori or Buonsignori (died 21 September 1589, in Florence) was an Italian Olivetan monk and cartographer to Francesco I, Grand Duke of Tuscany. He was born in Florence and is most notable for his eponymous Bonsignori Map of Florence.
Little is known about Bonsignori's life before he came to be in the service of the Medicis. He was born in Florence and became part of the Olivetan monastic order before being invited in 1575 to become Francesco's cartographer. [1]
According to a letter sent to the superior of his congregations, the Grand Duke intended to entrust him with the completion of the cycle of maps for the Guardaroba (cloakroom) in the Palazzo Vecchio, which remained unfinished after the dismissal of Ignazio Danti. Of the 53 cartographic panels painted on the doors of the cloakroom, 23 are by Bonsignori, with the most recent one being from 1589. [2] [3]
His famous axonometric map of Florence was created under the patronage of Francesco between 1576 and 1584 and etched by Bonaventura Billocardi. [4] [5] The prominence of the Arno River and the detailed depiction of a variety of often quite minor water-related structures is telling of the way in which water management had been an important aspect of the policies of Francesco's father, Cosimo I, whose achievements had transformed the city's landscape. [6]
In 1588 his role as Grand Ducal cartographer was confirmed by Francesco's successor, Ferdinando I. [7]
Stefano Bonsignori died in 1589 [1] and was buried in the church of Santi Michele e Gaetano, but his tomb disappeared during the seventeenth-century reconstruction of the building. [7]
Pope Leo XI, born Alessandro Ottaviano de' Medici, was head of the Catholic Church and ruler of the Papal States from 1 April 1605 to his death, on 27 April 1605. His pontificate is one of the briefest in history, having lasted under a month. He was from the prominent House of Medici originating from Florence. Medici's mother opposed his entering the priesthood and sought to prevent it by having him given secular honours, but after her death he eventually was ordained a priest in 1567. In his career he served as Florence's ambassador to the pope, Bishop of Pistoia, Archbishop of Florence, Papal legate to France, and as the cardinal Prefect for the Congregation of Bishops and Regulars. He was elected to the papacy in the March 1605 papal conclave and served as pope for 27 days.
The House of Medici was an Italian banking family and political dynasty that first consolidated power in the Republic of Florence under Cosimo de' Medici, 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 order was permanently abolished in 1859 by the annexation of Tuscany to the Kingdom of Sardinia. The former Kingdom of Italy and the current Italian Republic also did not recognize the order as a legal entity but tolerates it as a private body.
