Medieval geography


I have just uploaded a new chapter of my study about the revival of geographical knowledge in medieval Europe. It can be viewed at
Together with the previously uploaded parts
these four articles cover Unit I of my second project. The Unit’s title is “The Miraculous Revival or the Painful Recovery”. It is devoted to diverse aspects of mathematical geography as they were discovered by medieval scholars including the prospects of navigation through the world ocean.
I would be very grateful to have your comments.


Gog and Magog


My new research in the project concerns medieval legends referring to the East. The first part deals with Alexander’s Wall and Enclosed Nations. I’d like to expose the core of the legend: the construction of the Iron Gate by Alexander the Great to repel barbarian nomads and various conflations. For example, an association of imprisoned peoples with Gog and Magog of the Apocalypse. The link between their liberation and the Last Days. The identification of the oppressed people with different monsters: the Ten Lost Tribes of Israel, the Turks, and the Mongols. The confusion between the Caspian Gates and the Gates of the Caucasus.

My second project is devoted to links between the Latin West and the East. The first three chapters are available at my page at the site:

As I see from statistical reports, different readers have begun to get interested in my blog. You’re welcome to make comments concerning my project.

where I discuss my first book “Dawn and Sunset” whose second edition was published by Authorhouse this year.

Miraculous revival (2)


I have uploaded another two chapters from Unit 1 of my second book. You are welcome to view them at

and at

“How to Measure the Earth’s Circumference” offers a simple way of comparing different attempts to estimate the circumference. It turns out that Columbus was not alone in his underestimation.

“What is the Size of the Inhabited World” examines various models to estimate the size of the habitable world. These estimations matched the traditional three-continent concept popular with medieval geographers.

The final chapter of this unit is going to come.

Alexander’s Gate (1)


I have started another research connected to my second project. It is devoted to legends about the East which were influential in the Latin West throughout the Middle Ages. This time I am looking for Alexander’s Gate, Gog-Magog, and Enclosed Nations. Though well-researched, this topic deserves another attempt as the motivation to travel to and study about the East was warmed up by the circulation of certain tales. I will also delve into mappaemundi-a parallel world of medieval knowledge.
