The Natural History of Pliny (Vol. 1-6)

According to Pliny's definition, Natural History is a book about the natural world or life. It is the first encyclopedic work in history and a model for later encyclopedias. It is also the largest single work to have survived from the Roman Empire to the modern days. In this book, Pliny covers topics including astronomy, mathematics, geography, ethnography, anthropology, human physiology, zoology, botany, agriculture, horticulture, pharmacology, mining, mineralogy, sculpture, art, and precious stones. In total, the book consists of 10 volumes which contain 37 books. For Pliny, nature was divine. It was a pantheistic concept inspired by the Stoic philosophy. Also, according to this philosophy, the components of nature are described with a view to their role in human life. Pliny devotes a number of the books to plants, focusing on their medicinal value; the books on minerals include descriptions of their uses in architecture, sculpture, art, and jewelry.

Gaius Plinius Secundus (AD 23/24 - 79), also known as Pliny, the Elder, was a Roman author, natural philosopher, and naval and army commander of the Roman Empire. He was also a friend of the emperor Vespasian. As a writer, Pliny became famous for his encyclopedic Naturalis Historia (Natural History), which became one of the oldest known books of nature and an editorial model for encyclopedias. He spent most of his spare time studying, writing, and investigating natural and geographic phenomena in the field.
