Scope and Content
Administrative / Biographical History
The House of Medici was an Italian banking family, political dynasty and later a royal house, which rose to prominence in Florence during the first half of the fifteenth century, under Cosimo the Elder. The family had originated in the agricultural Mugello region of Tuscany, but its wealth derived from the Medici Bank, which grew to become the largest in Europe during the fifteenth century. This provided the wealth to support the Medicis' quest for political power in Florence.
Although Cosimo the Elder, his son Piero and grandson Lorenzo officially remained citizens rather than monarchs, they effectively ruled Florence, and through their enlightened patronage of the arts they transformed the city-state into the centre of the Renaissance. In 1531 the family became hereditary Dukes of Florence. In 1569 the Duchy was elevated to a Grand Duchy after territorial expansion. The Medici ruled the Grand Duchy of Tuscany from its inception until 1737, with the death of Gian Gastone de' Medici.
The Medici produced three Popes - Leo X (1513-21), Clement VII (1523-34), and Leo XI (1605) - and two regent queens of France: Catherine de' Medici (1547-59) and Marie de' Medici (1600-10).
Conditions Governing Access
The collection is open to any accredited reader.
Many items in the collection were purchased by the John Rylands Library at auction at Christie's on 26-28 May 1919, via Bernard Quaritch Ltd. The total purchase price was £72.
MDC/52 (accession no. R48226) and MDC/53-189 (accession no. R48225) were purchased by the John Rylands Library from the bookseller Percy Mordaunt Barnard of Royal Tunbridge Wells on 3 September 1920, for 19s and £3 12s respectively (catalogue 122, items 368-9). It has not been possible to identify these items in the catalogue of the Christie's sale in May 1919, and they are thus presumed not to have derived from the sale.
Other Finding Aids
The hand-list of the Medici Records was orginally published in Robert Fawtier, Hand-list of charters, deeds and similar documents in the possession of the John Rylands Library, I: documents of which the provenance has been ascertained (Manchester, 1925).
The retail magnate H. Gordon Selfridge (1858-1947) purchased the largest portion of the Medici Records sold at Christie's in May 1919, including the letters of Lorenzo de' Medici and a collection of ledgers, account books and memoranda of the Medici as bankers. In 1927 Selfridge deposited these items in the Baker Library at Harvard Business School. They constitute the largest collection of Renaissance Florentine account books outside Italy. They are described in outline at http://id.lib.harvard.edu/aleph/000603012/catalog.
Many of the documents in this collection derive from the archives of the younger branch of the Florentine family of the Medici and belonged until the early twentieth century to the Marquis Cosimo and the Marquis Averardo de' Medici. The whole of these archives was intended to be sold at Christie's in London in February 1918. However, the Italian Government exercised its right of preemption and 174 lots were withdrawn and transferred to the Italian state archives. The original sale was cancelled, and the remaining lots were eventually put up for sale at Christie's on 26-28 May 1919. The John Rylands Library purchased lots 1, 8-14, 26-28, 41-42, 49-52, 58-61, 72, 75, 530-534, 560-562, 607 and 609.
The previous provenance of MDC/52 and MDC/53-189, which were purchased from the bookseller P. M. Barnard in 1920, is unknown.
The John Rylands Library's accession number (R-----) and, where relevant, the lot number in the Christie's sale of May 1919 are recorded at the end of the Scope and Content note for each item.
