How Long Spans the Inhabited World

 As the previous discussion on my paper, How to Measure the Earth's Circumference, has ended, I decided to launch another discussion. You can view the article at https://www.academia.edu/s/849a19ddfc/how-long-spans-the-inhabited-world?source=work

This new paper continues the overview of the mathematical geography of the European Middle Ages and focuses on the extent of the known world. Besides reading, you can participate in the discussion during the remaining three weeks. 

As you have probably noticed, I made a resolution to abstain from uploading new pieces until I take most of my articles through discussions. This is a new feature added by the Academia.edu site last summer. I think that my work deserves a chance of attracting better publicity. Especially, due to the reaction of literary agents who consider my book unsellable to the general public. The credit that I get from my readers enables me to continue. 

Meanwhile, I was asked to give a lecture on Skype to the participants of the Russian political club who are interested in Jewish history. I am preparing notes about Mesha king of Moab and his rebellion against the Israelite oppressors. The lecture draws on the Moabite Stone and mentions in passing the Hebrew Bible since I can't accept the latter as the historical source, especially for the period before the seventh century BCE. 

I continue to develop materials for galleys and sailing ships of the Late Middle Ages. In the first chapter of a new unit, I will overview these two types of medieval ships, showing their strong and weak points, their role in shipping, and the kind of cargo that they were able to haul.
