Naturales quaestiones

Naturales quaestiones is a Latin encyclopedia of the natural world written by Seneca around 65 AD. It is much shorter than the Naturalis Historia produced by Pliny the Elder some ten years later. It is one of the few Roman works which deals with scientific matters, although is not a systematic work, but a collection of facts of nature from various writers, Greek and Roman. Moral remarks are scattered through the work; and the intent of the encyclopedia appears to be to discover a foundation for ethics in the knowledge of nature.
