But, as a matter of course, in the early Church and throughout the Middle Ages all such studies were cast in a theologic mould. Without some purpose of biblical ill.u.s.tration or spiritual edification they were considered futile too much prying into the secrets of Nature was very generally held to be dangerous both to body and soul; only for showing forth G.o.d"s glory and his purposes in the creation were such studies praiseworthy. The great work of Aristotle was under eclipse. The early Christian thinkers gave little attention to it, and that little was devoted to transforming it into something absolutely opposed to his whole spirit and method; in place of it they developed the Physiologus and the Bestiaries, mingling scriptural statements, legends of the saints, and fanciful inventions with pious intent and childlike simplicity. In place of research came authority--the authority of the Scriptures as interpreted by the Physio Cogus and the Bestiaries--and these remained the princ.i.p.al source of thought on animated Nature for over a thousand years.
Occasionally, indeed, fear was shown among the rulers in the Church, even at such poor prying into the creation as this, and in the fifth century a synod under Pope Gelasius administered a rebuke to the Physiologus; but the interest in Nature was too strong: the great work on Creation by St. Basil had drawn from the Physiologus precious ill.u.s.trations of Holy Writ, and the strongest of the early popes, Gregory the Great, virtually sanctioned it.
Thus was developed a sacred science of creation and of the divine purpose in Nature, which went on developing from the fourth century to the nineteenth--from St. Basil to St. Isidore of Seville, from Isidore to Vincent of Beauvais, and from Vincent to Archdeacon Paley and the Bridgewater Treatises.
Like all else in the Middle Ages, this sacred science was developed purely by theological methods. Neglecting the wonders which the dissection of the commonest animals would have afforded them, these naturalists attempted to throw light into Nature by ingenious use of scriptural texts, by research among the lives of the saints, and by the plentiful application of metaphysics. Hence even such strong men as St. Isidore of Seville treasured up accounts of the unicorn and dragons mentioned in the Scriptures and of the phoenix and basilisk in profane writings. Hence such contributions to knowledge as that the basilisk kills serpents by his breath and men by his glance, that the lion when pursued effaces his tracks with the end of his tail, that the pelican nourishes her young with her own blood, that serpents lay aside their venom before drinking, that the salamander quenches fire, that the hyena can talk with shepherds, that certain birds are born of the fruit of a certain tree when it happens to fall into the water, with other ma.s.ses of science equally valuable.
As to the method of bringing science to bear on Scripture, the Physiologus gives an example, ill.u.s.trating the pa.s.sage in the book of Job which speaks of the old lion perishing for lack of prey. Out of the attempt to explain an unusual Hebrew word in the text there came a curious development of error, until we find fully evolved an account of the "ant-lion," which, it gives us to understand, was the lion mentioned by Job, and it says: "As to the ant-lion, his father hath the shape of a lion, his mother that of an ant; the father liveth upon flesh and the mother upon herbs; these bring forth the ant-lion, a compound of both and in part like to either; for his fore part is like that of a lion and his hind part like that of an ant. Being thus composed, he is neither able to eat flesh like his father nor herbs like his mother, and so he perisheth."
In the middle of the thirteenth century we have a triumph of this theological method in the great work of the English Franciscan Bartholomew on The Properties of Things. The theological method as applied to science consists largely in accepting tradition and in spinning arguments to fit it. In this field Bartholomew was a master.
Having begun with the intent mainly to explain the allusions in Scripture to natural objects, he soon rises logically into a survey of all Nature. Discussing the "c.o.c.katrice" of Scripture, he tells us: "He drieth and burneth leaves with his touch, and he is of so great venom and perilous that he slayeth and wasteth him that nigheth him without tarrying; and yet the weasel overcometh him, for the biting of the weasel is death to the c.o.c.katrice. Nevertheless the biting of the c.o.c.katrice is death to the weasel if the weasel eat not rue before. And though the c.o.c.katrice be venomous without remedy while he is alive, yet he looseth all the malice when he is burnt to ashes. His ashes be accounted profitable in working of alchemy, and namely in turning and changing of metals."
Bartholomew also enlightens us on the animals of Egypt, and says, "If the crocodile findeth a man by the water"s brim he slayeth him, and then he weepeth over him and swalloweth him."
Naturally this good Franciscan naturalist devotes much thought to the "dragons" mentioned in Scripture. He says: "The dragon is most greatest of all serpents, and oft he is drawn out of his den and riseth up into the air, and the air is moved by him, and also the sea swelleth against his venom, and he hath a crest, and reareth his tongue, and hath teeth like a saw, and hath strength, and not only in teeth but in tail, and grieveth with biting and with stinging. Whom he findeth he slayeth.
Oft four or five of them fasten their tails together and rear up their heads, and sail over the sea to get good meat. Between elephants and dragons is everlasting fighting; for the dragon with his tail spanneth the elephant, and the elephant with his nose throweth down the dragon.... The cause why the dragon desireth his blood is the coldness thereof, by the which the dragon desireth to cool himself. Jerome saith that the dragon is a full thirsty beast, insomuch that he openeth his mouth against the wind to quench the burning of his thirst in that wise.
Therefore, when he seeth ships in great wind he flieth against the sail to take the cold wind, and overthroweth the ship."
These ideas of Friar Bartholomew spread far and struck deep into the popular mind. His book was translated into the princ.i.p.al languages of Europe, and was one of those most generally read during the Ages of Faith. It maintained its position nearly three hundred years; even after the invention of printing it held its own, and in the fifteenth century there were issued no less than ten editions of it in Latin, four in French, and various versions of it in Dutch, Spanish, and English.
Preachers found it especially useful in ill.u.s.trating the ways of G.o.d to man. It was only when the great voyages of discovery subst.i.tuted ascertained fact for theological reasoning in this province that its authority was broken.
The same sort of science flourished in the Bestiaries, which were used everywhere, and especially in the pulpits, for the edification of the faithful. In all of these, as in that compiled early in the thirteenth century by an ecclesiastic, William of Normandy, we have this lesson, borrowed from the Physiologus: "The lioness giveth birth to cubs which remain three days without life. Then cometh the lion, breatheth upon them, and bringeth them to life.... Thus it is that Jesus Christ during three days was deprived of life, but G.o.d the Father raised him gloriously."
Pious use was constantly made of this science, especially by monkish preachers. The phoenix rising from his ashes proves the doctrine of the resurrection; the structure and mischief of monkeys proves the existence of demons; the fact that certain monkeys have no tails proves that Satan has been shorn of his glory; the weasel, which "constantly changes its place, is a type of the man estranged from the word of G.o.d, who findeth no rest."
The moral treatises of the time often took the form of works on natural history, in order the more fully to exploit these religious teachings of Nature. Thus from the book On Bees, the Dominican Thomas of Cantimpre, we learn that "wasps persecute bees and make war on them out of natural hatred"; and these, he tells us, typify the demons who dwell in the air and with lightning and tempest a.s.sail and vex mankind--whereupon he fills a long chapter with anecdotes of such demonic warfare on mortals.
In like manner his fellow-Dominican, the inquisitor Nider, in his book The Ant Hill, teaches us that the ants in Ethiopia, which are said to have horns and to grow so large as to look like dogs, are emblems of atrocious heretics, like Wyclif and the Hussites, who bark and bite against the truth; while the ants of India, which dig up gold out of the sand with their feet and h.o.a.rd it, though they make no use of it, symbolize the fruitless toil with which the heretics dig out the gold of Holy Scripture and h.o.a.rd it in their books to no purpose.
This pious spirit not only pervaded science; it bloomed out in art, and especially in the cathedrals. In the gargoyles overhanging the walls, in the grotesques clambering about the towers or perched upon pinnacles, in the dragons prowling under archways or lurking in bosses of foliage, in the apocalyptic beasts carved upon the stalls of the choir, stained into the windows, wrought into the tapestries, illuminated in the letters and borders of psalters and missals, these marvels of creation suggested everywhere morals from the Physiologus, the Bestiaries, and the Exempla.(14)

Here and there among men who were free from church control we have work of a better sort. In the twelfth and thirteenth centuries Abd Allatif made observations upon the natural history of Egypt which showed a truly scientific spirit, and the Emperor Frederick II attempted to promote a more fruitful study of Nature; but one of these men was abhorred as a Mussulman and the other as an infidel. Far more in accordance with the spirit of the time was the ecclesiastic Giraldus Cambrensis, whose book on the topography of Ireland bestows much attention upon the animals of the island, and rarely fails to make each contribute an appropriate moral. For example, he says that in Ireland "eagles live for so many ages that they seem to contend with eternity itself; so also the saints, having put off the old man and put on the new, obtain the blessed fruit of everlasting life." Again, he tells us: "Eagles often fly so high that their wings are scorched by the sun; so those who in the Holy Scriptures strive to unravel the deep and hidden secrets of the heavenly mysteries, beyond what is allowed, fall below, as if the wings of the presumptuous imaginations on which they are borne were scorched."
In one of the great men of the following century appeared a gleam of healthful criticism: Albert the Great, in his work on the animals, dissents from the widespread belief that certain birds spring from trees and are nourished by the sap, and also from the theory that some are generated in the sea from decaying wood.
But it required many generations for such scepticism to produce much effect, and we find among the ill.u.s.trations in an edition of Mandeville published just before the Reformation not only careful accounts but pictured representations both of birds and of beasts produced in the fruit of trees.(15)
(15) For Giraldus Cambrensis, see the edition in the Bohn Library, London, 1863, p. 30; for the Abd Allatif and Frederick II, see Hoefer, as above; for Albertus Magnus, see the De Animalibus, lib. xxiii; for the ill.u.s.trations in Mandeville, see the Strasburg edition, 1484; for the history of the myth of the tree which produces birds, see Max Muller"s lectures on the Science of Language, second series, lect. xii.
This general employment of natural science for pious purposes went on after the Reformation. Luther frequently made this use of it, and his example controlled his followers. In 1612, Wolfgang Franz, Professor of Theology at Luther"s university, gave to the world his sacred history of animals, which went through many editions. It contained a very ingenious cla.s.sification, describing "natural dragons," which have three rows of teeth to each jaw, and he piously adds, "the princ.i.p.al dragon is the Devil."
Near the end of the same century, Father Kircher, the great Jesuit professor at Rome, holds back the sceptical current, insists upon the orthodox view, and represents among the animals entering the ark sirens and griffins.
Yet even among theologians we note here and there a sceptical spirit in natural science. Early in the same seventeenth century Eugene Roger published his Travels in Palestine. As regards the utterances of Scripture he is soundly orthodox: he prefaces his work with a map showing, among other important points referred to in biblical history, the place where Samson slew a thousand Philistines with the jawbone of an a.s.s, the cavern which Adam and Eve inhabited after their expulsion from paradise, the spot where Balaam"s a.s.s spoke, the place where Jacob wrestled with the angel, the steep place down which the swine possessed of devils plunged into the sea, the position of the salt statue which was once Lot"s wife, the place at sea where Jonah was swallowed by the whale, and "the exact spot where St. Peter caught one hundred and fifty-three fishes."
As to natural history, he describes and discusses with great theological acuteness the basilisk. He tells us that the animal is about a foot and a half long, is shaped like a crocodile, and kills people with a single glance. The one which he saw was dead, fortunately for him, since in the time of Pope Leo IV--as he tells us--one appeared in Rome and killed many people by merely looking at them; but the Pope destroyed it with his prayers and the sign of the cross. He informs us that Providence has wisely and mercifully protected man by requiring the monster to cry aloud two or three times whenever it leaves its den, and that the divine wisdom in creation is also shown by the fact that the monster is obliged to look its victim in the eye, and at a certain fixed distance, before its glance can penetrate the victim"s brain and so pa.s.s to his heart.
He also gives a reason for supposing that the same divine mercy has provided that the crowing of a c.o.c.k will kill the basilisk.
Yet even in this good and credulous missionary we see the influence of Bacon and the dawn of experimental science; for, having been told many stories regarding the salamander, he secured one, placed it alive upon the burning coals, and reports to us that the legends concerning its power to live in the fire are untrue. He also tried experiments with the chameleon, and found that the stories told of it were to be received with much allowance: while, then, he locks up his judgment whenever he discusses the letter of Scripture, he uses his mind in other things much after the modern method.
In the second half of the same century Hottinger, in his Theological Examination of the History of Creation, breaks from the belief in the phoenix; but his scepticism is carefully kept within the limits imposed by Scripture. He avows his doubts, first, "because G.o.d created the animals in couples, while the phoenix is represented as a single, unmated creature"; secondly, "because Noah, when he entered the ark, brought the animals in by sevens, while there were never so many individuals of the phoenix species"; thirdly, because "no man is known who dares a.s.sert that he has ever seen this bird"; fourthly, because "those who a.s.sert there is a phoenix differ among themselves."
In view of these attacks on the salamander and the phoenix, we are not surprised to find, before the end of the century, scepticism regarding the basilisk: the eminent Prof. Kirchmaier, at the University of Wittenberg, treats phoenix and basilisk alike as old wives" fables. As to the phoenix, he denies its existence, not only because Noah took no such bird into the ark, but also because, as he pithily remarks, "birds come from eggs, not from ashes." But the unicorn he can not resign, nor will he even concede that the unicorn is a rhinoceros; he appeals to Job and to Marco Polo to prove that this animal, as usually conceived, really exists, and says, "Who would not fear to deny the existence of the unicorn, since Holy Scripture names him with distinct praises?"
As to the other great animals mentioned in Scripture, he is so rationalistic as to admit that behemoth was an elephant and leviathan a whale.
But these germs of a fruitful scepticism grew, and we soon find Dannhauer going a step further and declaring his disbelief even in the unicorn, insisting that it was a rhinoceros--only that and nothing more.
Still, the main current continued strongly theological. In 1712 Samuel Bochart published his great work upon the animals of Holy Scripture. As showing its spirit we may take the t.i.tles of the chapters on the horse:
"Chapter VI. Of the Hebrew Name of the Horse."
"Chapter VII. Of the Colours of the Six Horses in Zechariah."
"Chapter VIII. Of the Horses in Job."
"Chapter IX. Of Solomon"s Horses, and of the Texts wherein the Writers praise the Excellence of Horses."
"Chapter X. Of the Consecrated Horses of the Sun."
Among the other t.i.tles of chapters are such as: Of Balaam"s a.s.s; Of the Thousand Philistines slain by Samson with the Jawbone of an a.s.s; Of the Golden Calves of Aaron and Jeroboam; Of the Bleating, Milk, Wool, External and Internal Parts of Sheep mentioned in Scripture; Of Notable Things told regarding Lions in Scripture; Of Noah"s Dove and of the Dove which appeared at Christ"s Baptism. Mixed up in the book, with the princ.i.p.al ma.s.s drawn from Scripture, were many facts and reasonings taken from investigations by naturalists; but all were permeated by the theological spirit.(16)

The inquiry into Nature having thus been pursued nearly two thousand years theologically, we find by the middle of the sixteenth century some promising beginnings of a different method--the method of inquiry into Nature scientifically--the method which seeks not plausibilities but facts. At that time Edward Wotton led the way in England and Conrad Gesner on the Continent, by observations widely extended, carefully noted, and thoughtfully cla.s.sified.
This better method of interrogating Nature soon led to the formation of societies for the same purpose. In 1560 was founded an Academy for the Study of Nature at Naples, but theologians, becoming alarmed, suppressed it, and for nearly one hundred years there was no new combined effort of that sort, until in 1645 began the meetings in London of what was afterward the Royal Society. Then came the Academy of Sciences in France, and the Accademia del Cimento in Italy; others followed in all parts of the world, and a great new movement was begun.
Theologians soon saw a danger in this movement. In Italy, Prince Leopold de" Medici, a protector of the Florentine Academy, was bribed with a cardinal"s hat to neglect it, and from the days of Urban VIII to Pius IX a similar spirit was there shown. In France, there were frequent ecclesiastical interferences, of which Buffon"s humiliation for stating a simple scientific truth was a noted example. In England, Protestantism was at first hardly more favourable toward the Royal Society, and the great Dr. South denounced it in his sermons as irreligious.
Fortunately, one thing prevented an open breach between theology and science: while new investigators had mainly given up the medieval method so dear to the Church, they had very generally retained the conception of direct creation and of design throughout creation--a design having as its main purpose the profit, instruction, enjoyment, and amus.e.m.e.nt of man.
On this the naturally opposing tendencies of theology and science were compromised. Science, while somewhat freed from its old limitations, became the handmaid of theology in ill.u.s.trating the doctrine of creative design, and always with apparent deference to the Chaldean and other ancient myths and legends embodied in the Hebrew sacred books.
About the middle of the seventeenth century came a great victory of the scientific over the theologic method. At that time Francesco Redi published the results of his inquiries into the doctrine of spontaneous generation. For ages a widely accepted doctrine had been that water, filth, and carrion had received power from the Creator to generate worms, insects, and a mult.i.tude of the smaller animals; and this doctrine had been especially welcomed by St. Augustine and many of the fathers, since it relieved the Almighty of making, Adam of naming, and Noah of living in the ark with these innumerable despised species.
But to this fallacy Redi put an end. By researches which could not be gainsaid, he showed that every one of these animals came from an egg; each, therefore, must be the lineal descendant of an animal created, named, and preserved from "the beginning."
Similar work went on in England, but under more distinctly theological limitations. In the same seventeenth century a very famous and popular English book was published by the naturalist John Ray, a fellow of the Royal Society, who produced a number of works on plants, fishes, and birds; but the most widely read of all was ent.i.tled The Wisdom of G.o.d manifested in the Works of Creation. Between the years 1691 and 1827 it pa.s.sed through nearly twenty editions.
Ray argued the goodness and wisdom of G.o.d from the adaptation of the animals not only to man"s uses but to their own lives and surroundings.
