The Basilisk and Cockatrice in Medieval Bestiaries

Record summary

The basilisk tradition describes a deadly serpent, sometimes linked to a cockerel, whose gaze, breath, or presence kills. In later medieval and early modern forms, the cockatrice acquires increasingly composite features, occasionally including wings. This is a useful comparison case for how textual transmission transforms a dangerous animal into a winged monster through copying, translation, illustration, and moral allegory. The material is best treated as bestiary literature rather than evidence of an encountered creature. Different manuscripts and languages do not preserve one stable description.
