The Jack of Lent was a puppet with fish emblems and was used as a target during Lent and destroyed on Palm Sunday.
When Jakke a' Lent comes justlynge in,
With the hedpeece of a herynge,
And saythe, repent yowe of yower syn,
For shame, syrs, leve yowre swerynge:
And to Palme Sonday doethe he ryde,
With sprots and herryngs by his syde,
And makes an end of Lenten tyde!
