Riaz Dean’s The Stone Tower: Ptolemy, the Silk Road, and a 2,000-year-old Riddle investigates the identity of a landmark associated with Ptolemy’s Geographia and the Silk Road. Dean argues that the landmark mattered to travellers along the overland trade network. The available excerpt, however, does not identify the location he ultimately proposes or establish that specialists accept his solution.
What is the Stone Tower riddle?
The question at the heart of Dean’s book is where the Stone Tower described in connection with Ptolemy’s geographical writing was located. The puzzle links ancient geography with the Silk Road, a network of routes used by caravans travelling, trading, resting and obtaining provisions.

In an excerpt published by Scroll.in on March 10, 2022, Dean calls the Stone Tower an important landmark for Silk Road travellers. He says, “The answer lies at several levels but simply put, it was the most important landmark for travellers along the Silk Road.” That is Dean’s interpretation, rather than an independently established finding in the excerpt.
Why is identifying it difficult?
Ptolemy’s coordinates are approximate
The excerpt notes that coordinates attributed to Ptolemy were approximate. That makes a modern identification more than a matter of plotting a precise point: the geographical clues must be interpreted in context. The excerpt also observes that Ptolemy’s account includes numerous towns and physical features, while ancient writers were less familiar with the region east of Bactria.

#1 Best Overall
A landmark could clarify more than one map location
Dean’s argument, as described in the excerpt, is that locating a major landmark or midpoint on the route could help resolve broader questions in historical geography and cartography. This explains why the Stone Tower matters to his investigation; it does not, by itself, demonstrate that a particular site is the correct one.

The Scroll headline describes the book as solving the riddle, but the excerpt does not disclose Dean’s proposed location, lay out the evidence for it, or report how other specialists assess it. On the evidence available there, the claim should be understood as the book’s framing, not as confirmation of a scholarly consensus. Readers who want to assess the proposed identification need the full argument in The Stone Tower: Ptolemy, the Silk Road, and a 2,000-year-old Riddle and relevant independent specialist work.

What the excerpt establishes—and what it does not
- Established in the excerpt: The book is by Riaz Dean, concerns Ptolemy and the Silk Road, and presents the Stone Tower as an important landmark for travellers.
- Important qualification: The coordinates attributed to Ptolemy are described as approximate, and the region east of Bactria was less familiar to ancient writers.
- Not established in the excerpt: Dean’s final proposed location, the detailed case for it, or independent acceptance of that identification.
