Early Lighthouses

A new work in Pharology

When it is published, Early Lighthouses will become the second volume of three in Ken Trethewey' Pharology Series. The first volume, Ancient Lighthouses (2018), presented a complete description of how humans first developed their ideas of lighted aids to navigation and how the lighthouse was first conceived and built. The book covers the period from the first years when humans travelled by water to the year 400 when the Roman Empire had grown used to relatively safe and effective sea transport with its own network of lighthouses.

In this second volume, Early Lighthouses, the period from 400 to 1700 will be covered, a span of time that ranges from the Dark Ages (500 to 1000) through the Medieval Period (1000 to 1500) to the start of the Industrial Age. The book is expected to be published in 2020.

The third and final volume of the series will cover Contemporary Lighthouses from 1700 to the Present Day.

Early Lighthouses is one of a very few books in recent years that will seriously address the subject of early lighthouses and their origins. The scope will be expansive and will bring readers to the beginning of the Industrial Age - the contents of Volume 3, expected in 2022.
