The author, born in 1929.
In 1961 the Yemeni scholar Ahmad Husayn Sharafaddin published a short book in English of about 80 pages entitled Yemen “Arabia Felix.” The book was published in Rome Italy, but distributed from Ta‘izz. It provides a short summary of Yemen just before the revolution that toppled the Zaydi imamate.
As narrated by the author, the population of Yemen was estimated at 5,834,000 with 4,400,000 in what he called “Free Yemen” (the Mutawakkilite Kingdom) and 1,434,000 in the “Occupied area” under the British. The city of Ṣan‘ā’ was said to have 60,000 residents and Ta‘izz had half that amount.
Most of the book is devoted to the archaeology of the ancient South Arabian kingdoms.
One of the highlights is a pull-out chart of the genealogy of the Zaydi imams.
Of particular interest are the pictures, as noted here.
