The magical fabric known as sea silk

King Solomon was said to wear a golden tunic, lighter than a feather made of it, and ancient Greeks and Egyptians used to pin a piece of this shining fabric on their robes as a sign of wealth.

Chiara Vigo - who lives in a remote village in Sardinia, Italy - still weaves sea silk. It's made from Byssus - a fine filament produced by large molluscs under the sea. Chiara uses traditional chants to ensure a good harvest. (Photo: Andrea Pasquali)
