"The acephalous horseman is also well known in Northamptonshire; and though our dialect is not rich enough to afford him a particular designation, we may boast possession of this veritable Dul hallan. He is confined to no particular district, but common to almost every parish in the county. On a calm summer's night, when the pale glimmer of the young moon scarcely penetrates the dark foliage of the trees, he may be seen mounted on his silent-hoofed steed, slowly riding along the green-sward border of some old green lane or lonely road, and woe to the benighted traveller who crosses his path. His appearance is generally regarded as ominous of evil, often death." - Thomas Sternberg, The dialect and folk-lore of Northamptonshire.
