since prehistory. The first known written record of the plant is found in Qimin Yaoshu, an ancient Chinese agricultural treatise completed in 544 CE. The numerous Arabic and North African names for it, along with the lack of the ancient Greek and Roman names, indicate it was grown throughout the Mediterranean area by the Arabs in the early Middle Ages, who introduced it to Spain in the 8th century. A book on agriculture by Ibn Al-Awwam in 12th-century Arabic Spain described how to grow aubergines. Records exist from later medieval Catalan and Spanish. The aubergine is unrecorded in England until the 16th century. An English botany book in 1597 described the madde or raging Apple: Because of the plant's relationship with various other nightshades, the fruit was at one time believed to be extremely poisonous. The flowers and leaves can be poisonous if consumed in large quantities due to the presence of solanine. The eggplant has a special place in folklore. In 13th-century Italian traditional folklore, the eggplant can cause insanity. In 19th-century Egypt, insanity was said to be "more common and more violent" when the eggplant is in season in the summer. Etymology and regional names The plant and fruit have a profusion of English names. Eggplant-type names The name eggplant is usual in North American English and Australian English. First recorded in 1763, the word "eggplant" was originally applied to white cultivars, which look very much like hen's eggs (see image). Similar names are widespread in other languages, such as the Icelandic term eggaldin or the Welsh planhigyn ŵy. The white, egg-shaped varieties of the eggplant's fruits are also known as garden eggs, a term first attested in 1811. The Oxford English Dictionary records that between 1797 and 1888, the name vegetable egg was also used. Aubergine-type names Whereas eggplant was coined in English, most of the diverse other European names for the plant derive from the Arabic word bāḏinjān (). Bāḏinjān is itself a loan-word in Arabic, whose earliest traceable origins lie in the Dravidian languages. The Hobson-Jobson dictionary comments that 'probably there is no word of the kind which has undergone such extraordinary variety of modifications, whilst retaining the same meaning, as this'. In English usage, modern names deriving from Arabic bāḏinjān include: Aubergine, usual in British English (as well as German, French and Dutch). Brinjal or brinjaul, usual in South Asia and South African English.
