allegorical is Ezekiel 16 and 17, wherein the capture of that same vine by the mighty Eagle represents Israel's exile to Babylon. Allegorical interpretation of the Bible was a common early Christian practice and continues. For example, the recently re-discovered Fourth Commentary on the Gospels by Fortunatianus of Aquileia has a comment by its English translator: "The principal characteristic of Fortunatianus' exegesis is a figurative approach, relying on a set of concepts associated with key terms in order to create an allegorical decoding of the text." Medieval allegory Allegory has an ability to freeze the temporality of a story, while infusing it with a spiritual context. Mediaeval thinking accepted allegory as having a reality underlying any rhetorical or fictional uses. The allegory was as true as the facts of surface appearances. Thus, the Papal Bull Unam Sanctam (1302) presents themes of the unity of Christendom with the pope as its head in which the allegorical details of the metaphors are adduced as facts on which is based a demonstration with the vocabulary of logic: "Therefore of this one and only Church there is one body and one head—not two heads as if it were a monster... If, then, the Greeks or others say that they were not committed to the care of Peter and his successors, they necessarily confess that they are not of the sheep of Christ." This text also demonstrates the frequent use of allegory in religious texts during the Mediaeval Period, following the tradition and example of the Bible. In the late 15th century, the enigmatic Hypnerotomachia, with its elaborate woodcut illustrations, shows the influence of themed pageants and masques on contemporary allegorical representation, as humanist dialectic conveyed them. The denial of medieval allegory as found in the 12th-century works of Hugh of St Victor and Edward Topsell's Historie of Foure-footed Beastes (London, 1607, 1653) and its replacement in the study of nature with methods of categorisation and mathematics by such figures as naturalist John Ray and the astronomer Galileo is thought to mark the beginnings of early modern science. Modern allegory Since meaningful stories are nearly always applicable to larger issues, allegories may be read into many stories which the author may not have recognised. This is allegoresis, or the act of reading a story as an allegory. Examples of allegory in popular culture that may or may not have been intended include the works of
