The history of botany examines the human effort to understand life on Earth by pharmaceutics lecture notes pdf download the historical development of the discipline of botany—that part of natural science dealing with organisms traditionally treated as plants.

Rudimentary botanical science began with empirically-based plant lore passed from generation to generation in the oral traditions of paleolithic hunter-gatherers. 17th centuries heralded a scientific revival during which botany gradually emerged from natural history as an independent science, distinct from medicine and agriculture. During the Neolithic Revolution plant knowledge increased most obviously through the use of plants for food and medicine. All of today’s staple foods were domesticated in prehistoric times as a gradual process of selection of higher-yielding varieties took place, possibly unknowingly, over hundreds to thousands of years. It is also from the Neolithic, in about 3000 BC, that we glimpse the first known illustrations of plants and read descriptions of impressive gardens in Egypt. Other examples of early Indian taxonomy include Manusmriti, the Law book of Hindus, which classifies plants into eight major categories.

Ancient Athens, of the 6th century BC, was the busy trade centre at the confluence of Egyptian, Mesopotamian and Minoan cultures at the height of Greek colonisation of the Mediterranean. The philosophical thought of this period ranged freely through many subjects. Athens with its tradition of peripatetic philosophy. The Lyceum prided itself in a tradition of systematic observation of causal connections, critical experiment and rational theorizing. Theophrastus challenged the superstitious medicine employed by the physicians of his day, called rhizotomi, and also the control over medicine exerted by priestly authority and tradition. Meanwhile, the study of medicinal plants was not being neglected and a full synthesis of ancient Greek pharmacology was compiled in Materia Medica c.

Greek physician with the Roman army. The Romans contributed little to the foundations of botanical science laid by the ancient Greeks, but made a sound contribution to our knowledge of applied botany as agriculture. Roman writers contributed to a compendium Scriptores Rei Rusticae, published from the Renaissance on, which set out the principles and practice of agriculture. Theophrastus but with a lack of botanical insight although he does, nevertheless, draw a distinction between true botany on the one hand, and farming and medicine on the other. It is estimated that at the time of the Roman Empire between 1300 and 1400 plants had been recorded in the West. In Western Europe, after Theophrastus, botany passed through a bleak period of 1800 years when little progress was made and, indeed, many of the early insights were lost. China, India and the Arab world enjoyed a golden age.

Chinese philosophy had followed a similar path to that of the ancient Greeks. The 400-year period from the 9th to 13th centuries AD was the Islamic Renaissance, a time when Islamic culture and science thrived. Greco-Roman texts were preserved, copied and extended although new texts always emphasised the medicinal aspects of plants. Ottoman Empire welcomed European embassies in its capital, which in turn became the sources of plants from those regions to the east which traded with the empire. Dioscorides’, De Materia Medica, Byzantium, 15th century. In the European Middle Ages of the 15th and 16th centuries the lives of European citizens were based around agriculture but when printing arrived, with movable type and woodcut illustrations, it was not treatises on agriculture that were published, but lists of medicinal plants with descriptions of their properties or “virtues”. Herbals contributed to botany by setting in train the science of plant description, classification, and botanical illustration.

The revival of learning during the European Renaissance renewed interest in plants. The church, feudal aristocracy and an increasingly influential merchant class that supported science and the arts, now jostled in a world of increasing trade. The number of scientific publications increased. During the 18th century botany was one of the few sciences considered appropriate for genteel educated women. Around 1760, with the popularization of the Linnaean system, botany became much more widespread among educated women who painted plants, attended classes on plant classification, and collected herbarium specimens although emphasis was on the healing properties of plants rather than plant reproduction which had overtones of sexuality. Public and private gardens have always been strongly associated with the historical unfolding of botanical science. Early botanical gardens were physic gardens, repositories for the medicinal plants described in the herbals.

As they were generally associated with universities or other academic institutions the plants were also used for study. Buildings called herbaria housed these specimens mounted on card with descriptive labels. By the 18th century the physic gardens had been transformed into “order beds” that demonstrated the classification systems that were being devised by botanists of the day — but they also had to accommodate the influx of curious, beautiful and new plants pouring in from voyages of exploration that were associated with European colonial expansion. Plant classification systems of the 17th and 18th centuries now related plants to one another and not to man, marking a return to the non-anthropocentric botanical science promoted by Theophrastus over 1500 years before. In England, various herbals in either Latin or English were mainly compilations and translations of continental European works, of limited relevance to the British Isles.
