Nature and Language [PDF ebook] 
A Semiotic Study of Cucurbits in Literature

There exists an area of overlap where language and nature meet, and this book, first published in 1980, illuminates that fascinating territory. When real-world things, such as plants, are used in literature or language as symbols, these special signs have a double allegiance. They function as language but derive their meaning from nature. The authors trace the consequences of this, and show how it affects the character of the relevant areas of language and literature. Original and entertaining, this study cuts across a number of traditional disciplines. It should appeal not only to those interested in literature, language and semiotics, but also to students of philosophy, anthropology, classics, pictorial art, religion and folklore.
