The Track Walker of the Diolkos
A Novel of Ancient Greece's Stone Railway

About this book:

In the narrow waist of Greece, where the Saronic and Corinthian Gulfs nearly kiss, a five-mile stone railway has hauled ships overland for three centuries. The Diolkos is Corinth's lifeline—limestone grooves cut to a precision of fingers, greased with lard and pitch, bearing the weight of triremes and grain hulls alike. Nikias has walked every inch of it for thirty years. He knows which fractures breathe and which are dead, how the clay swells beneath the flags, and exactly how much ox-tallow buys a safe passage. When he finds fresh limestone dust and iron flakes at the summit curve—a gauge widened by three-eighths of an inch—he knows someone has broken the machine on purpose.

What follows is a thriller built on friction and leverage: a naval dispatch that cannot wait, a trireme too fragile for a compromised track, and a saboteur who understands that the Diolkos is not merely a road but a calculation of physics, geology, and human greed. Nikias must trace the fault through salt quarries and slave gangs, past harbor masters cooking ledgers and exiles guarding secrets, all while the autumn rains swell the clay beneath the stone. The engineering is real, the stakes are commercial and mortal, and the detective work is done with calipers, plumb-bobs, and a track-walker's fingertips.

Steven Saylor meets *The Name of the Rose* on the Isthmus of Corinth. *The Track Walker of the Diolkos* turns one of antiquity's greatest forgotten technologies into a stage for murder, commerce, and the quiet heroism of the men who kept the ancient world moving—one greased groove at a time.
