This section highlights the role of the Venetian fleet in the siege of Zara (Zadar, Croatia) and delves into the tensions within the crusading camp, while discussing the campaign's ultimate goal. https://www.academia.edu/128273374/The_Fall_of_New_Rome_Part_2_The_Sack_of_Zara  I am in the process of editing the third and final part of my account. Additionally, I have uploaded the revised version of Chapter 3 of my book, "The Enchanting Encounter with the East." This updated chapter presents an enhanced version of the final chapter of Unit I: The Three Trick Questions of Mathematical Geography. It explores how medieval European scholars understood the extent of the inhabited world. Drawing on the calculations...

How to Measure the Earth’s Circumference?

I have completed the second chapter of my book. This section tells about different approaches to the issue of estimating the Earth's circumference. You can read the first page where I explain how I picked up the medium for the estimation.   If the earth is a globe, its circumference can be roughly determined. The two giants of the ancient world endeavored to carry out this tremendous task. Both of them estimated the angle of elevation of heavenly bodies above the horizon at distant points presumably located on the same meridian in order to reach the measure of one degree. They also assessed the distance between these spots by converting travel days on land (1) or at sea (2) into an accepted standard of length. The fact that each of these estimations held versions proves that the scholars were not happy with their initial scores and, being confronted with sound criticism, had to improve their performance. The degree of uncertainty only grows if we take into account the in...
