The most famous reference to divination by cabbage is in Robert Burns' poem "Halloween":
Then, first and foremost, through the kail,
Their stocks maun a' be sought ance;
They steek their een, and graip and wale,
For muckle anes and straught anes.
Poor hav'rel Will fell aff the drift,
And wander'd through the bow-kail,
And pou't, for want o' better shift,
A runt was like a sow-tail,
Sae bow't that night.
