<P> As the dominant view of philosophers and thinkers continued to be in favour of spontaneous generation, some Christian theologians accepted the view . Augustine of Hippo discussed spontaneous generation in The City of God and The Literal Meaning of Genesis, citing Biblical passages such as "Let the waters bring forth abundantly the moving creature that hath life" (Genesis 1: 20) as decrees that would enable ongoing creation . </P> <P> From the fall of the Roman Empire in 5th century to the East - West Schism in 1054, the influence of Greek science declined, although spontaneous generation generally went unchallenged . New descriptions were made . Of the numerous beliefs, some had doctrinal implications outside of the Book of Genesis . For example, the idea that a variety of bird known as the barnacle goose emerged from a crustacean known as the goose barnacle, had implications on the practice of fasting during Lent . In 1188, Gerald of Wales, after having traveled in Ireland, argued that the "unnatural" generation of barnacle geese was evidence for the virgin birth . Where the practice of fasting during Lent allowed fish, but prohibited fowl, the idea that the goose was in fact a fish suggested that its consumption be permitted during Lent . The practice was eventually prohibited by decree of Pope Innocent III in 1215 . </P> <P> Aristotle, in Arabic translation, was reintroduced to Western Europe . During the 13th century, Aristotle reached his greatest acceptance . With the availability of Latin translations Saint Albertus Magnus and his student, Saint Thomas Aquinas, raised Aristotelianism to its greatest prominence . Albert wrote a paraphrase of Aristotle, De causis et processu universitatis, in which he removed some and incorporated other commentaries by Arabic scholars . The influential writings of Aquinas, on both the physical and metaphysical, are predominantly Aristotelian, but show numerous other influences . </P> <P> Spontaneous generation is discussed as a fact in literature well into the Renaissance . Where, in passing, Shakespeare discusses snakes and crocodiles forming from the mud of the Nile (Ant 2.7 F1), Izaak Walton again raises the question of the origin of eels "as rats and mice, and many other living creatures, are bred in Egypt, by the sun's heat when it shines upon the overflowing of the river ...". While the ancient question of the origin of eels remained unanswered and the additional idea that eels reproduced from corruption of age was mentioned, the spontaneous generation of rats and mice engendered no debate . </P>
