History of formation of knowledge about mammals

 during the medieval period

 

During the medieval epoch the fauna was one of the main natural resources on which production of goods and applied branches of knowledge were based. Optimum development, the use of the animal population in practical aims demanded generalization of available data, reception of the new ones from various geographical regions, their comparison and the analysis. This was favored by the expansion of trading communications, the search of the new ways to gain material resources, the development of a colonizer policy of the largest medieval states. Duplicating and distribution of the collected data became possible due to the occurrence of publishing in 1440.

Trading communications of Hindus and Arabs served as the main channel to exchange and receive the new information at early stages of the Middle Ages. Approximately in 900 Abu Suleiman delivered lots of zoogeographical data from China and India. Works written by Al-Biruni (1000) contain a lot of data about the animals of the Indo-China and Hindustan. Al-Biruni touches upon some other important questions on the distinctions (including faunistic) between the continents and oceanic islands whereas investigations in the field of the history of formation of faunae of various territories became a subject of scientific discussion only in the XIX-th century. The Arabian researchers gave the world not only materials about the countries of the East, but also described European cities; they summurized and analyzed data from written sources of Greeks, Romans, Persians, Hindus, etc.

"The European school" of naturalists also continues to develop. The Norwegian work "Speculum of the kings" (1000) appeared at that period of time. The characteristic feature of this period was the generalization and critical reassessment of the data contained in the sources of the Ancient world, also enlarged with the new materials. For instance, the dominican monk Albert Veliky (1193-1280) in the 26-volume work generalizes and critically analyzes Aristotel’s works, "The Natural History" by Thomas Kanteprja (XIII century) and expands them with the regional zoogeographical data about Germany, which he received during his own long-term observations. It is remarkable, that he also describes the geographical zonality of animals expansion.

The English scientist Roger Bacon (1214-1292), developing an idea of the Spanish thinker of the XI-th century Raimund de Sabied that one should not be content only with Aristotel’s works to acquire the knowledge about nature. Only the knowledge of the nature can increase the prosperity of mankind, and for this purpose it should be studied. He drew up some kind of program of biogeographical investigations consisting of two basic stages: 1) descriptions of all objects (that now is referred to as inventory of the biological variety) at a level of species and their biomes and 2) the explanation of reasons taking place in the nature of processes, a way of life of the alive organisms, existing interrelations, etc. In his opinion the investigations should be carried out by the principle: from particular (facts) to the whole (generalization). The interesting fact is that the development of the "regional component" in zoogeographical investigations coincides with the time of the concept of descriptive regional geography formation in the general geography (Øàëüíåâ, 2000), that proves the closest interrelations in investigations of the animal population and its value as one of leading factors in the development of geographical knowledge in general.

In the book "the Mirror of the nature" (1258) frenchmen Vikentiy and Bove showed the consequences of the erosive processes, i.e. transformation of natural complexes under the influence of the external reasons causing also the changes in the animal population of the territory, this can be considered as the first description of biocenose pauperization.

The revolution of nautical art which took place in the XIII-th century favoured the development of natural-science knowledge of the described period both technical (shipbuilding), as well as scientific and technical character (the development of cartography, invention of a compass, etc.). It allowed to stir up the travel, to expand geography and navigation for the further distances. One of the first and thorough geographical descriptions was work "About the variety of the world ", written by the  Venetian merchant Marko Polo who had been traveling across China since 1271 till 1295. He also visited India, Ceylon, Burma, Arabia and brought many data on Siberia. Describing the travel, Marko Polo (1955) paid the greatest attention to enumeration of various animals (from insects up to mammals). Under his descriptions it is possible not only to make faunistic lists of various territories, but also to evaluate the number of separate species in this or that region.

The period called "the Epoch of Great geographical discoverings" became the most significant stage of the Middle Ages. Voyages by Hristofor Columbus (in 1492-1504), Vasko da Gamma (1498), Fernana Magellan (1519) and other seafarers contributed into creation of the works containing many data on the animal population. Thus, for example, Klusius (born in 1526) and Oviedo published works in which they provided data on known at that time "overseas" animals, in particular American sirens, armadillo, slothes, fishes. Markgrave described the animals of Africa, de Bont (Bontious) – the Dutch India, Olearii, Persia; ̀àăèñåđ Madagascar. Hristofor Columbus, describing mountains on the Espaniola island (Haiti), pointed out, that they were covered with evergreen woods and there were many birds (Hristofor Columbus's Travel..., 1956). It enabled to receive data on the fauna world of the different continents, the remote territories. That contributed the accumulation of the comparative and geographical data and materials for systematization, to represent a picture of a specific variety of the Earth animal population as a whole.
