Giovanni Arduino

Giovanni Arduino 1714 - 1795 was a mining specialist who developed possibly the first classification of geological time, based on study of the geology of northern Italy. The first record of the classification may be a letter dated from 1759 - dates on the web vary. His classification used only a few periods: primitive (or primary), secondary and tertiary - some pages on the web add a forth type, variously quaternary, volcanic or alluvial.

Giovanni Arduino appears to be also a present-day fiction writer from Turin, Italy.
