What happened

Gervase of Tilbury, an English lawyer and courtier, compiled the Otia Imperialia ('Recreation for an Emperor') for Emperor Otto IV, finishing around 1211. Among its marvels is this one. On a dark, cloudy feast day, parishioners leaving their church find a ship's anchor caught in a heap of stones in the churchyard, its rope rising straight up into the sky. As they watch, the rope jerks as if unseen sailors are trying to pull the anchor free, and voices are heard in the thick air above. Then a sailor climbs down the rope hand over hand. When bystanders seize him, he gasps like a drowning man and dies, suffocated by our thicker, wetter air. After about an hour the crew overhead cut the rope and sail off, leaving the anchor, which was made into ironwork for the church door. Gervase says the ironwork could still be seen in his day. He also tells of a Bristol sailor's knife that dropped overboard far out at sea and fell through the skylight of his own house.

The official explanation

Scholars see Gervase's story as one version of an Irish tale that developed over centuries. It began with the annal note of ships in the air (c. 749), grew into the Teltown spear story, and became the Clonmacnoise anchor legend, which was then retold in London (Geoffroy du Breuil, set in 1122), in Britain (Gervase) and in the Norse King's Mirror. Gervase believed literally in a sea above the sky, and the story served to illustrate that cosmology. Popular UFO books later misdated it to 1270 and placed it in Bristol.

The anomalous case

Read as an encounter report, Gervase's version has details later UFO narratives repeat. An unseen craft is anchored overhead in low cloud, voices are heard from it, and the rope moves under tension. A crew member comes down and cannot survive in our atmosphere, and the rest abandon him and leave. The ironwork made from the anchor was, Gervase says, still on the church door: a claimed physical relic. A congregation is a group of witnesses, and 'suffocated in our air' is a striking description for a 13th-century writer to choose. Modern UFO literature, quoted in the Condon Report, retold it as a crew member who 'asphyxiated in the earth's atmosphere'. Proponents argue that the story's survival across Ireland, England, France and Norway shows how strongly the core encounter was remembered.

The strongest argument that this was something genuinely unknown or classified, with each claim attributed to the person who made it.
