Mycenaean Greek (Linear B)

Coriander is one of the oldest documented spices in human history—its name appears in Linear B clay tablets from 1200 BCE Mycenaean Greece, and its seeds were found in an 8,000-year-old cave in the Levant. Half the world loves it; the other half says it tastes like soap—and that disagreement is written into their DNA.

The earliest written record of coriander is a Linear B clay tablet from the Mycenaean palace at Knossos on Crete, dated to approximately 1200 BCE. The syllabic script records the word ko-ri-ja-da-na, reconstructed as koriadnon—close to the name of the Minoan princess Ariadne, which may suggest a mythological connection or simply reflect the accident of sound. Before that, dried coriander seeds were found in the Pre-Pottery Neolithic layers of Nahal Hemar Cave in the Judean Desert, dating to approximately 6,000–8,000 BCE, making coriander one of the earliest spices with direct archaeological evidence. Its seeds also appear in ancient Egyptian tombs.

The ancient Greek word koriandron, from which Latin coriandrum and English coriander descend, was connected by Greek writers to kóris—the bedbug—on account of the fresh leaves' pungent, allegedly bug-like smell. This etymology has been debated: some linguists argue the plant name came first and the bedbug comparison was a folk etymology invented later. In either case, the association with an insect smell is linguistically embedded in the word itself, which gives the coriander-haters of history a certain vindication.

Coriander spread across the ancient world through multiple routes. It is mentioned in the Old Testament (Numbers 11:7), where manna is compared to coriander seeds. Arab traders carried it from the eastern Mediterranean to India and Southeast Asia. Spanish conquistadors introduced it to the Americas in the 1500s, where it hybridized culturally with pre-existing cuisines: cilantro (the Spanish word for coriander, used in English to distinguish the fresh herb from the dried seeds) became essential to Mexican, Peruvian, and Caribbean cooking.

In 2012, researchers at the University of Toronto published a genome-wide association study identifying OR6A2—an olfactory receptor gene—as the primary genetic driver of cilantro aversion. Variants in OR6A2 make the aldehydes present in fresh coriander leaf smell and taste overwhelmingly of soap. The trait is most common in people of European and East Asian descent, and least common in people of South Asian, Middle Eastern, and Latin American ancestry—precisely the populations with the longest culinary history of using the herb. The gene has not changed; the cultural relationship with the plant did.

Coriander is the rare spice that carries a genetic argument in its name. The word's bedbug etymology and the soap-tasters' OR6A2 gene are both pointing at the same phenomenon: the aldehydes in fresh coriander leaf are chemically distinctive, and whether they read as food or as chemical contamination depends entirely on which olfactory receptors you inherited.

The Mycenaean scribe who pressed ko-ri-ja-da-na into wet clay at Knossos could not have anticipated that eight thousand years of culinary history would be sorted by a gene. The spice is older than alphabets. The disagreement over whether it belongs in food is apparently almost as old.
