About this listen
 Discover the wonders of the natural world through Naturalis Historia, an incredible encyclopedia authored by Pliny the Elder around AD 77-79. This monumental work stands as one of the largest surviving texts from the Roman Empire, ambitiously covering the vast expanse of ancient knowledge. Pliny meticulously references original sources, creating a model for all subsequent encyclopedias with its extensive subject matter and comprehensive indexing. The text is divided into two main realms the organic world of plants and animals, and the inorganic domain of minerals and metals, enriched with insightful digressions. Pliny goes beyond mere description, examining how humanity, particularly the Romans, interacts with nature—both in its appreciation and exploitation. This third volume features books eleven to fifteen, delving into the fascinating topics of insects, trees, exotic flora, and fruit trees, offering a treasure trove of knowledge for history enthusiasts and nature lovers alike.

  • Treatise on Light-Christiaan Huygens

    Treatise on Light-Christiaan Huygens
    Nov 7 2026
    Treatise on Light by Christiaan Huygens.

    Treatise on Light was published in 1690 and is probably the largest scientific volume on light published before Newton's Opticks. The book explains how light travels (i.e., that it has a certain velocity), and what happens when it hits a surface (refraction and reflection). A large portion of the book is devoted to the double refraction occurring in Iceland chrystal, and all drawn conclusions are proved geometrically. Christiaan Huygens (1629 - 1695) was a prominent physicist and astronomer. His main discoveries are the centrifugal force, collision laws for bodies and the argument that light consists of waves. He was a contemporary of Galilei and Descartes, and a member of the French Royal Society since 1663.
