The Heilbrunn Timeline of World Art, on the Metropolitan Museum of Art site, is a garden of delights in which one can easily become lost. It now includes over 6000 items and more are being added. Covering the time period from 20,000 BCE to the present, the site allows exploration by keyword or subject, name of artist, time period, country or region, time period and region, medium, and more. You can even sort the alphabetical list of essays by region or time period, see a cultural time line (e.g. Central and North Asia, 8000–2000 B.C.), or search for something specific in both the Timeline and the Met’s overall collection database. I searched for “hat,” and found 2020 hits in The Costume Institute, and 75 in the Heilbrunn Timeline itself.
I arrived at this site while googling prehistoric Japanese sculpture (of the “Jomon” culture) and then somehow found myself looking at Moroccan embroidery and a 19th c. American quilt using squares with the signatures of notables of the time such as Ralph Waldo Emerson.
Each item has at least one photo that can be viewed in two sizes, a short description, and perhaps most enticing, links to other pieces related by time period, region, or material. Short essays are provided for many topics. Here’s one on the American Arts and Crafts movement; here’s one on a site in China, dated to 7000 BCE, with pictograms and bone flutes–”the earliest playable musical instruments” found (disputable, but let’s not carp).
Go to the list of artists and sort them according to medium or type of work: performance artist, calligrapher, painter, weapons maker, architect, metal worker, etc.
If this sounds wide rather than deep, who can complain? African Rock Art, Albrecht Dürer, Arms and Armor—Common Misconceptions and Frequently Asked Questions, Ancient Greek Dress, Botanical Imagery in European Painting, the Bikini, the Bronze Age, the Bauhaus…if I had to choose a few sites to be able to access on a desert island, this might make the list. (All of the foregoing are thematic essays on the A-B page.)
Above, embroidered panel, ca. 1800, Morocco.
Linen, silk; 9 ft. x 32 1/2 in. (274.3 x 82.5 cm)
Purchase, Everfast Fabrics Inc. Gift, 1970 (1970.272)
One of the rarest and finest examples of Moroccan embroidery, this wall hanging (arid) displays the most remarkable achievement of a Chechaouene needlewoman’s skills. The arids were used to cover the surrounding areas of interior arches in matching sets. Worked in plaited stitch, these panels contain geometric motifs based on tracery, arabesques, stars, rectangles, and diamonds, all closely associated with Andalusian elements. Said to have been used as an altar curtain in a Nestorian church in Jerusalem, this particular piece is certainly conversant with a variety of cultures and civilizations. The importance of embroidery in Moroccan life can be illustrated by the ceremony held for every infant girl at the age of four months, when the baby was placed in a chair and given a needle and thimble along with some silk thread to hold, in anticipation of a life blessed with the needle’s art.

Above, detail, Autograph quilt, ca. 1856–63, by Adeline Harris Sears (American, 1839–1931). Silk with inked signatures; 77 x 80 in. (195.6 x 203.2 cm).

In 1856, seventeen-year-old Adeline Harris, the daughter of a well-to-do Rhode Island mill owner, conceived of a unique quiltmaking project. She sent small diamond-shaped pieces of white silk worldwide to people she esteemed as the most important figures of her day, asking each to sign the silk and return it to her. By the time the signatures were all returned and ready to be stitched into a “tumbling-blocks” patterned quilt, Adeline had amassed an astonishing collection of autographs. Her quilt features the signatures of eight American presidents; luminaries from the worlds of science, religion, and education; heroes of the Civil War; such authors as Charles Dickens and Ralph Waldo Emerson; and an array of prominent artists. Today, the autographs displayed in this beautiful and immaculately constructed quilt provide an intriguing glimpse into the way an educated young woman of the mid-nineteenth century viewed her world.

Below, one result of the “hat” search: [Cornelius Conway Felton with His Hat and Coat], early 1850s
John Adams Whipple (American, 1822–1891)
Daguerreotype; Each 3 1/4 x 2 3/4 in. (8.3 x 7 cm)
The Rubel Collection, Purchase, Lila Acheson Wallace, W. Bruce and Delaney H. Lundberg, and Ann Tenenbaum and Thomas H. Lee Gifts, 1997 (1997.382.41)
This rare daguerreotype diptych shows Cornelius Conway Felton (1807–1862), Eliot Professor of Greek Literature at Harvard University, reaching for his felt hat and duster. The first son of a poverty-stricken furniture maker, Felton became one of the most renowned classical scholars in the country and, in 1860, Harvard’s president. Although Felton donned academic robes, he never lost his connection to the everyday experiences of common folk. As opposed to the inflexible silk top hat worn by dandies and professors alike, the broad-brimmed felt duster that co-stars here was worn by outdoorsmen and was practical, casual, and fundamentally democratic.
