Timeline Treasures·1235 works·72 museums·69 countries and regions
Every work here is a treasure its own museum chose to single out — collected one country or region at a time so that nothing is missed, then set on a single unbroken line of time, from painted clay to the modern age, each in the museum’s own words.

A flute made from the left thighbone of a young cave bear and pierced with four holes, found in the Divje babe cave near Cerkno; the museum presents it as the oldest known musical instrument in the world (about 60,000 years old) and the only one definitely made by Neanderthals.

Migration-period jewellery and dress ornaments of gold, silver, bronze, garnet and glass from the Lajh cemetery at Kranj (ancient Carnium), worn by Germanic women in the 6th century; the museum notes that the garnets inlaid in the gilded brooches and belt buckles came from as far away as India or Sri Lanka.

A Gothic Madonna and Child carved around 1390 in the 'Beautiful Style' (Schöne Stil), her body swayed into an S-curve with her weight on her right leg and her head tilted toward her right shoulder and slightly downward, her gaze directed toward the Christ Child on her left arm. The museum's own digital collection record (translated from Polish) calls it a key work among the international group of 'Beautiful Madonnas', related to the Beautiful Madonna of Toruń. Its original provenance is undocumented: the sculpture is traditionally associated with a Wrocław church, most often identified as St Elizabeth's, though the museum's own records describe this link as unconfirmed. The association reportedly arose from a mistaken swap of an identification card, with St Mary Magdalene's church named as an equally plausible alternative, and the museum's curatorial commentary states plainly that 'the place for which this figure was made is unknown.'

painting by Leonardo da Vinci in the Louvre

painting by Johannes Vermeer

The revolutionary journalist Jean-Paul Marat lies dead in his medicinal bath, stabbed by his assassin Charlotte Corday, her letter of introduction still in his hand and a quill fallen from the other - painted by David, a friend and fellow revolutionary, within months of Marat's 1793 murder, as an image of secular martyrdom for the Revolution. The wooden crate beside the bath is inscribed with David's dedication, transcribed on the museum's own catalog record (translated from French) as 'A MARAT, / DAVID / L'AN-DEUX' ('To Marat, David, Year Two' of the French Republican calendar). Widely regarded as the single most famous painting in the museum's collection.

painting by Jean-Auguste-Dominique Ingres

A pared-back portrait of the artist's wife, Amélie, built from simple geometric structure and bold, unmodulated planes of colour rather than conventional light and shadow – one of Matisse's most celebrated paintings and a landmark of twentieth-century portraiture, painted after his Fauvist summer with André Derain in Collioure.
Ways of seeing
Every museum’s choice of treasures is a way of seeing the past. Dot area counts the works of each kind collected in each country or region; the last column is the share of that location's collection gathered from civilisations outside its main traditions — the difference between a mirror and a window.
