We judge from these facts that the bean was cultivated in Europe in prehistoric terms. It was introduced into Europe probably by the western Aryans at the time of their earliest migrations (Pelasgians, Kelts, Slavs). It was taken to China later, a century before the Christian era, and still later into Japan, and quite recently into India.
Its wild habitat was probably twofold some thousands of years ago, one of the centres being to the south of the Caspian, the other in the north of Africa. This kind of area, which I have called disjunctive, and to which I formerly paid a good deal of attention,[1603] is rare in dicotyledons, but there are examples in those very countries of which I have just spoken.[1604] It is probable that the area of the bean has long been in process of diminution and of extinction. The nature of the plant is in favour of this hypothesis, for its seed has no means of dispersing itself, and rodents or other animals can easily make prey of it. Its area in Western Asia was probably less limited at one time, and that in Africa in Pliny’s day was more or less extensive. The struggle for existence which was going against this plant, as against maize, would have gradually isolated it and caused it to disappear, if man had not saved it by cultivation.
The plant which most nearly resembles the bean is Vicia narbonensis. Authors who do not admit the genus Faba, of which the characters are not very distinct from those of Vicia, place these two species in the same section. Now, Vicia narbonensis is wild in the Mediterranean basin and in the East as far as the Caucasus, in the north of Persia, and in Mesopotamia.[1605] Its area is continuous, but this renders the hypothesis I mentioned above probable by analogy.
Lentil—Ervum lens, Linnæus; Lens esculenta, Mœnch.
The plants which most nearly resemble the lentil are classed by authors now in the genus Ervum, now in a distinct genus Lens, and sometimes in the genus Cicer; but the species of these ill-defined groups all belong to the Mediterranean basin or to Western Asia. This throws some light on the origin of the cultivated plant. Unfortunately, the lentil is no longer to be found in a wild state, at least with certainty. The floras of the south of Europe, of Northern Africa, of the East, and of India always mention it as cultivated, or as growing in fields after or with other cultivated species. A botanist[1606] saw it in the provinces to the south of the Caucasus, “cultivated and nearly wild here and there round villages.” Another[1607] indicates it vaguely in the south of Russia, but more recent floras fail to confirm this.
The history and names of this plant may give clearer indications of its origin. It has been cultivated in the East, in the Mediterranean basin and even in Switzerland, from prehistoric time. According to Herodotos, Theophrastus, etc., the ancient Egyptians used it largely. If their monuments give no proof of this, it was probably because the lentil was, like the bean, considered common and coarse. The Old Testament mentions it three times, by the name adaschum or adaschim, which must certainly mean lentil, for the Arabic name is ads,[1608] or adas.[1609] The red colour of Esau’s famous mess of pottage has not been understood by most authors. Reynier,[1610] who had lived in Egypt, confirms the explanation given formerly by Josephus; the lentils were red because they were hulled. It is still the practice in Egypt, says Reynier, to remove the husk or outer skin from the lentil, and in this case they are a pale red. The Berbers have the Semitic name adès for the lentil.[1611]
The Greeks cultivated the species—fakos or fakai. Aristophanes mentions it as an article of food of the poor.[1612] The Latins called it lens, a name whose origin is unknown, which is evidently allied to the ancient Slav lesha, Illyrian lechja, Lithuanian lenszic.[1613] The difference between the Greek and Latin names shows that the species perhaps existed in Greece and Italy before it was cultivated. Another proof of ancient existence in Europe is the discovery of lentils in the lake-dwellings of St. Peter’s Island, Lake of Bienne,[1614] which are of the age of bronze. The species may have been introduced from Italy.
According to Theophrastus,[1615] the inhabitants of Bactriana (the modern Bokkara) did not know the fakos of the Greeks. Adolphe Pictet quotes a Persian name, mangu or margu, but he does not say whether it is an ancient name, existing, for instance, in the Zend Avesta. He admits several Sanskrit names for the lentil, masura, renuka, mangalya, etc., while Anglo-Indian botanists, Roxburgh and Piddington, knew none.[1616] As these authors mention an analogous name in Hindustani and Bengali, mussour, we may suppose that masura signifies lentil, while mangu in Persian recalls the other name mangalya. As Roxburgh and Piddington give no name in other Indian languages, it may be supposed that the lentil was not known in this country before the invasion of the Sanskrit-speaking race. Ancient Chinese works do not mention the species; at least, Dr. Bretschneider says nothing of them in his work published in 1870, nor in the more detailed letters which he has since written to me.
The lentil appears to have existed in western temperate Asia, in Greece, and in Italy, where its cultivation was first undertaken in very early prehistoric time, when it was introduced into Egypt. Its cultivation appears to have been extended at a less remote epoch, but still hardly in historic time, both east and west, that is into Europe and India.
