## Summary

A half-length portrait of a girl of about seventeen turning to look past the viewer, with a white animal in the crook of her arm, painted in oil on a single walnut board in Milan around 1490 and attached by most scholars, though by no document, to Cecilia Gallerani, the mistress of Ludovico Sforza. A portrait of her by Leonardo was in her hands in 1498, when Isabella d'Este borrowed it to compare Leonardo with Giovanni Bellini; the Krakow panel then leaves the record for about 300 years, nothing documenting its owners between 1498 and the purchase in Italy around 1800.Prince Adam Jerzy Czartoryski bought it in Italy around 1800 for his mother's collection at Pulawy. It was hidden, taken to Paris, brought to Krakow, seized by the Germans in 1939, was in Hans Frank's hands during the war, probably at the Wawel, and was found in Bavaria in 1945. A 2012 museum study found the black background is later overpaint over a plain dark grey; Pascal Cotte's 2014 book, drawing on a 2007 multispectral scan, argued there was once no ermine at all, a thesis the museum's conservators reject.No price for the picture alone is recorded. On 29 December 2016 the Polish state bought the whole Czartoryski collection, about 86,000 museum objects and 250,000 library items, for 100 million euros, an agreement signed that day according to the Ministry of Culture and Apollo. The picture is now on permanent view at the Princes Czartoryski Museum in Krakow.

## Provenance

Every link carries a grade. `documented` means a cited source supports it, `disputed` means the identification is argued but not established, `unknown` means we have no owner for that span and have not bridged it.

- **c. 1489-c. 1491** Made at the court of Ludovico Sforza, Milan, for a sitter conventionally identified as Cecilia Gallerani `[disputed]` (commission)
  Bucci writes that the portrait was wanted by Ludovico and executed by his favourite painter. No contract, payment or inventory entry for the picture is known. That the sitter is, as the title conventionally has it, Cecilia Gallerani is an inference widely shared but never documented, and the date is placed from 1485 to about 1508 by different authors.
- **c. 1491-1498** Cecilia Gallerani (Countess Bergamina) `[disputed]` (ownership)
  In letters of 26 and 29 April 1498 Isabella d'Este asks to borrow, and Cecilia sends, a portrait of Cecilia by Leonardo. She is its owner and lender; Bucci says the picture remained her property. The letters do not describe the picture, so their link to the Krakow panel rests on the identification above.
- **1498** Isabella d'Este, Marchioness of Mantua (on loan) `[documented]` (loan)
  Loan requested 26 April 1498 so that she could compare Leonardo with Giovanni Bellini; Cecilia replied 29 April; her third letter of 18 May answers Isabella's thanks. The Mantua catalogue says the painting was returned after about a month; the letters do not mention the return.
- **1498-c. 1536** Cecilia Gallerani, presumably until her death `[unknown]` (ownership)
  The 2015 museum paper says she probably owned it until her death in 1536 and cites Marani for the idea; there is no document. Her death date is itself not known (Bucci: 'around 1536').
- **c. 1536-c. 1798** Unknown `[unknown]` (gap)
  No owner is documented for about 260 years. The 2015 paper reads the oak cradle, the partial cleaning and the black ground as work done to prepare it for sale in Italy before the Czartoryski purchase. The Monuments Men and Women Foundation says it came from the Giustiniani collection, without citing a source, and the museum says it was bought at an unknown place in Italy.
- **1798-1800-1801** Prince Adam Jerzy Czartoryski `[disputed]` (purchase)
  The purchase is recorded by the museum, but its date and circumstances are not settled. Bought in Italy in circumstances the museum calls unknown and given to his mother. The date is 1798 in Wikipedia and the 2007 AFP report, 1799 or 1800 in the 2015 paper and about 1800 in the museum's own pages. No price is recorded.
- **c. 1801-1831** Princess Izabela Czartoryska, Pulawy (Gothic House from 1809, no. 418) `[documented]` (ownership)
  Shown as a portrait of a woman in the manuscript catalogues and printed in her 1828 catalogue as no. 418; given the La Belle Ferronniere inscription at Pulawy between 1800 and 1809.
- **1831-1882** Czartoryski family; hidden at Klemensow and Sieniawa, then at the Hotel Lambert, Paris `[documented]` (flight)
  Removed after the fall of Pulawy in 1831; walled up at Sieniawa for eight years (the 2015 paper dates this 1832-40); the family bought the Hotel Lambert in 1843 and the collection reached Paris through Dresden in 1848-49. The museum says it was not exhibited there. Dates differ slightly between the museum's pages and the paper.
- **1882-1914** Princes Czartoryski Museum, Krakow (family property) `[documented]` (ownership)
  Moved to the museum the family had opened in 1876. English-language sources that say it reached Krakow in 1876 are giving the museum's founding date.
- **1914-1920** Gemaldegalerie, Dresden (on deposit) `[documented]` (deposit)
  Sent for safe keeping in the First World War with the Raphael and Rembrandt. Hans Posse tried unsuccessfully to keep the collection in Germany (Monuments Men and Women Foundation).
- **1920-September 1939** Princes Czartoryski Museum, Krakow `[documented]` (ownership)
  Returned to Krakow in 1920; evacuated to Sieniawa in 1939.
- **September 1939-autumn 1939** German occupation authorities: Sieniawa, then Berlin (Muhlmann's office; Kaiser-Friedrich-Museum; a bank deposit box), reported `[disputed]` (seizure)
  The museum states that this picture was seized, with the Raphael and the Rembrandt, in a pre-planned looting and taken to Germany for the planned Linz museum. The Berlin stations come from the Monuments Men and Women Foundation's card on the Raphael, which treats the three paintings together and says they had 'likely' reached Muhlmann's Berlin office by November 1939, from post-war interrogations. The 2015 paper says only that the painting was exhibited in Berlin in 1939. Goering appointed Muhlmann on 6 October 1939.
- **1940-1945** Hans Frank, Governor General of occupied Poland (Wawel Castle 1940, Breslau 1941, Wawel 1943, Seichau Castle 1944, Bavaria 1945) `[documented]` (seizure)
  The museum says the picture came into Frank's hands and was in his possession through the war, probably at the Wawel; the 2015 paper gives the stations. The foundation's card adds that in January 1945 Frank took twenty paintings with him to Bavaria, among them this one.
- **1945-1946** Recovered by US forces in Frank's Bavarian villa; Monuments, Fine Arts and Archives officers; returned to Krakow via Nuremberg and the Wawel `[documented]` (recovery)
  X-rayed at the Doerner Institute, Munich, 1945; train from Nuremberg on 26 April 1946 (Apollo); at the Wawel 30 April to 8 May 1946; photographed in April 1946 with Monuments Men Albright and Lesley, Major Karol Estreicher and Pfc. Espinosa. Wikipedia names Schliersee; the sources read do not.
- **1946-23 September 1991** Princes Czartoryski Museum, Krakow (National Museum in Krakow), ownership in abeyance `[documented]` (deposit)
  The owner, Prince Augustyn Czartoryski, was in Spain and died within months of the picture's return (Apollo). A Polish court ruled on 14 March 1991 that Adam Karol Czartoryski was the sole heir, ending about fifty years in which ownership of the collection had been in abeyance.
- **23 September 1991-29 December 2016** Princes Czartoryski Foundation, on deposit at the National Museum in Krakow `[documented]` (ownership)
  Founded by Adam Karol Czartoryski by notarial deed, with the collection left on deposit. The Foundation arranged the foreign loans from 1991 to 2012 and, according to the Ministry of Culture, drew its main income from them.
- **29 December 2016-2017** State Treasury of Poland (Minister of Culture and National Heritage, Piotr Glinski) `[documented]` (purchase)
  Agreement signed that day for the purchase, with the rest of the Princes Czartoryski Museum and Library, for EUR 100 million (the Ministry and Apollo; no payment date was found), about 86,000 museum objects and 250,000 library items. The price is for the whole collection and is not a valuation of this picture. The Ministry says the Foundation had insured it for EUR 300 million for foreign loans. No auction sale of this picture is recorded in any source read, and no price for the picture alone appears in any source read.
- **2017-present** National Museum in Krakow (Princes Czartoryski Museum) `[documented]` (acquisition)
  Transferred to the National Museum in Krakow in 2017; the digital catalogue's origin field reads 'gift, 21 June 2017'. On show at the Wawel from 2012, at the main building from 19 May 2017 to 9 December 2019 and in the Czartoryski Museum since its reopening in December 2019.

## Open questions

- Where was the picture between Cecilia Gallerani's death (probably around 1536) and the Czartoryski purchase in 1798-1800? The 2015 museum paper says no evidence has been found, and the Monuments Men and Women Foundation's line that it came from the Giustiniani collection has no cited source.
- Who painted the black ground, when and why? Candidate answers in the sources: Italy before 1800 (the 2015 paper), Pulawy or Paris in the early or mid nineteenth century, the 1840s after the years walled up at Sieniawa (Rostworowski), or after the broken corner (Bull). The museum's own pages disagree with each other.
- Was there ever a state of the picture without the ermine? Cotte (2014) says yes, in three stages; the museum's conservators (2015) say the radiograph and pouncing traces show the animal was part of the design from the start. Neither side's raw data is open.
- Is the Krakow panel the portrait that Cecilia lent to Isabella d'Este in 1498? Nothing in the letters or in Bellincioni's sonnet describes it, and Boesten-Stengel (2021) argues the sonnet describes a different composition.
- What is the date? Estimates range from 1485-86 (Mantua State Archive catalogue note) through 1488-91 (Bucci, the museum, the 2012 committee minutes) to about 1507-08 (Boesten-Stengel).
- When was Ludovico invested in the Order of the Ermine, 1486 (Benzoni; Boesten-Stengel) or 1488 (Bucci following Pedretti; the museum)? The document that settles it was not found.
- Who removed the two patches of overpaint at the top right and lower right, and when? Munich in 1945-46 and Kozlowski in 1952 are the two candidates in the 2015 paper, which says neither recorded doing it.
- What did Leonardo receive for the portrait? No contract or payment has surfaced, and Cecilia's own 1,000-ducat inheritance seems not to have been paid by 1508.
- What do the label BURG / 1227 on the back and the label 134 mean? The second matches the entry number in the 1940 German catalogue of secured works, which was not seen.
- What did the 2024 Techne article by del Hoyo-Melendez and colleagues on the picture's materials and techniques add? It is listed in the museum's bibliography and was not reached.
- Is the picture on Poland's List of Heritage Treasures? Piotr Zuchowski said in 2013 that it should be; whether it was entered was not established.
- Where did the proceeds of the 2016 sale go? The Foundation says it moved its funds to a Liechtenstein foundation; the Liechtenstein authorities' inspection at the request of Poland's Supreme Audit Office has not been published.
