Small gold items discovered over several years by eight different metal detectorists may all be from a 16th-century hat

A very small treasure hoard - a handful of tiny fragments of beautifully worked Tudor gold - has been harvested from a muddy stretch of the Thames foreshore over a period of years by eight different metal detectorists.

The pieces all date from the early 16th century, and the style of the tiny pieces of gold is so similar that Kate Sumnall, an archaeologist, believes they all came from the disastrous loss of one fabulous garment, possibly a hat snatched off a passenger's head by a gust of wind at a time when the main river crossings were the myriad ferry boats.

Such metal objects, including aglets - metal tips for laces - beads and studs, originally had a practical purpose as garment fasteners but by the early 16th century were being worn in gold as high-status ornaments, making costly fabrics such as velvet and furs even more ostentatious. Contemporary portraits, including one in the National Portrait Gallery of the Dacres, Mary Neville and Gregory Fiennes, show their sleeves festooned with pairs of such ornaments.

Some of the Thames pieces are inlaid with enamel or little pieces of coloured glass. Despite the fact there is not enough gold in them to fill an egg cup, the pieces are legally treasure that must be declared to finds officers such as Sumnall, who is based at the Museum of London. She also records less valuable finds voluntarily reported under the portable antiquities scheme, and so has a good working relationship with the licensed mudlarks who scour the Thames shore between tides.

Sumnall said they were an important find as a huge amount of skill had been invested in the intricate pieces. "These artefacts have been reported to me one at a time over the last couple of years. Individually they are all wonderful finds but as a group they are even more important. To find them from just one area suggests a lost ornate hat or other item of clothing. The fabric has not survived and all that remains are these gold decorative elements that hint at the fashion of the time."

Once the pieces have been through a treasure inquest and valued, the museum hopes to acquire them all, still glittering after their centuries in the mud.
