The Anglo-Saxon was especially distinguished by his forcible images and epithets. In Rynerwulf we have 'night falls like a helmet, dark brown covers the mountains.' 'The sky is the fortress of the storm, the sun the torch of the world, the jewel of splendour.' 'Fire is eager, wild, blind, and raging; the sea is the gray sea, and the sparkling splendid sea; waves are graves of the dead,' etc. Vivid feeling for Nature is not among the characteristic features of either Scandinavian or old German poetry. It is naive and objective throughout, and seldom weighty or forcible. The Waltharius shews the influence of Virgil's language, in highly-coloured and sympathetic descriptions like those of the Latin poetry of the Carolingian Renaissance. Animal saga probably first arose just before the twelfth century, and their home was probably Franconia. Like the genial notices of plant life in the Latin poems of the Carlovingian period, the animal poems shewed interest in the animal world--the interest of a child who ponders individual differences and peculiarities, the virtues and failings so closely allied to its own. It was a naive 'hand-and-glove' footing between man and the creatures, which attributed all his wishes and weaknesses to them, wiped out all differences between them with perfect impartiality, and gave the characteristics of each animal with exactness and poetry. The soil for the cultivation of poetry about animals was prepared by the symbolic and allegorical way of looking at Nature which held sway all through the Middle Ages. The material was used as a symbolic language for the immaterial, the world of sense conceived of as a great picture-book of the truths of salvation, in whose pages God, the devil, and, between them man, figured: thus plant life suggested the flower of the root of Jesse, foretold by Isaiah, red flowers the Saviour's wounds, and so forth. In the earliest Christian times, a remarkable letter existed in Alexandria, the so-called 'Physiologus,' which has affected the proverbial turns of speech in the world's literature up to the present day to an almost unequalled degree.
