Before cochineal, Europe's luxury red came from tiny insects on oak trees, mistaken for grain.

Name
Sanskrit krmija, 'worm-made'
Replaced by
Cochineal, 16th century

Kermes is a red dye made from the dried bodies of a scale insect, Kermes vermilio, that lives on the kermes oak around the Mediterranean. Egyptians, Mesopotamians, Greeks and Romans used it, and jars of it have turned up in a Neolithic cave burial in Provence. Its color is a deep red, a true crimson.

The name traveled far. It goes back to Sanskrit krmija, 'made by a worm', then Persian and Arabic qirmiz, and from there to our words crimson and carmine. Medieval Europeans thought the dried insects were seeds and called the dye 'grain', so cloth dyed with it was 'dyed in the grain'.

In the Middle Ages, kermes-dyed scarlet wool and crimson silk were the most prized cloths in Europe, more desirable than the lost Tyrian purple. Wool dyed blue with woad and then dipped in kermes gave purples and near-blacks.

Then the Spanish brought cochineal from Mexico. It was several times stronger, so less was needed, and kermes faded from the market. The app's scarlet and crimson carry its legacy. The other great medieval red, vermilion, was a mineral, not a bug.
