# How the Private Cabinet Invented the Museum
> The Renaissance cabinet was an argument about its owner before it was a display of art, and the inventories prove it: in 1492 the Medici gems outvalued every painting in the house.

## Key points
- The 1492 inventory of the Palazzo Medici valued hardstone vases at about 27 per cent of the whole estate and all paintings, sculpture and small objets at roughly 5 per cent.
- Federico da Montefeltro's studiolo at Urbino, dated 1476, is a room that depicts a collection in wood rather than housing one.
- Samuel Quiccheberg printed the first theoretical treatise on museums in Munich in October 1565, before the Uffizi Tribuna was built.
- The most precise surviving record of Rudolf II's Kunstkammer after Froschl's inventory is the list of what Swedish troops carried away from Prague in 1648.
## The studiolo was an argument about its owner before it was a display of art
## The 1492 Medici inventory valued one cameo at a hundred times the best painting in the house
## Quiccheberg described the museum before anyone had built one
## Rudolf's Kunstkammer survives mainly in the record of its own dismantling
## The Tribuna is the point at which a cabinet becomes a gallery
The cabinet did not become a museum by growing. It became a museum when somebody wrote down what was in it in an order a stranger could follow, and when that writing outlived the owner. Urbino's illustrious men are divided between two countries, Rudolf's Kunstkammer is best reconstructed from a list of what was carried out of Prague, and the Medici holdings are still in Florence because a woman in Vienna signed a clause in 1737. In the history of collecting, the document is the institution.
## Questions
**Is the Gubbio studiolo securely attributed to Francesco di Giorgio?**
No. The Metropolitan Museum records that the room may have been designed by Francesco di Giorgio and that the intarsia was executed by Giuliano da Maiano, which is a deliberately soft formulation. The design attribution is a scholarly proposal, not a documented commission, and it should be cited as such.
**Why do early inventories so rarely name painters?**
Because they were drawn up for executors, not for art historians. The 1492 Palazzo Medici inventory values by material and weight, which is why hardstone vases account for about 27 per cent of the estate while all paintings and sculpture together account for about 5 per cent. Authorship was not the variable being measured.
**Where should a researcher look for objects from Rudolf II's Prague Kunstkammer?**
Vienna holds only parts of it. Because Swedish forces removed a very large and itemised quantity of material in 1648, including 470 paintings and 600 agate and rock-crystal vessels, Swedish collections and the seventeenth-century Swedish records are a necessary line of enquiry alongside Froschl's inventory of 1607 to 1611.
