Grant

The Grant is named and described in a single medieval compendium of marvels, Gervase of Tilbury's Otia Imperialia. In that source it is presented as "a kind of demon" that "runs through towns as a warning of fire." There is no earlier origin narrative recorded in the cited materials; later writers have attempted to relate the brief Otia account to wider vernacular motifs of horse-shaped bogies or to interpret it as an embellished record of animal-omens, but those are modern interpretive proposals rather than original origin stories.

In the sole medieval attestation (Gervase of Tilbury's Otia Imperialia) the Grant is described as resembling "a yearling colt, prancing on its hind-legs, with sparkling eyes." That equid-like image is the only direct physical description in the cited sources; later commentators have proposed alternative identifications (e.g., hare, water-spirit) but these are interpretive and not part of the original medieval wording.

The only recorded behaviour in the primary medieval account is that the Grant "runs through towns as a warning of fire," functioning as a portent. Modern scholars have proposed interpretive frameworks—linking it to a motif of horse-like bogies encountered on roads (púca, kelpie, shagfoal) or suggesting the report may reflect a hare-as-omen—these are presented in the secondary literature as hypotheses and not additional recorded powers.
