The late Dr. Ernie Haerinck is one of the most significant European archaeologists, who communicated with the Arab Gulf and carried out many archaeological excavations in the region. Most important of which was the excavation of the ed-Dur site in the Emirate of Umm Al Quwain, which is one of the most important archaeological sites in the Arabian Gulf, dating back to the period from the first century BC to the second century AD. Dr. Haerinck has published a number of works and research on the findings of the excavation at the site, one of which is this book, in which he, along with his team, excavated in ed-Dur temple and its surroundings. The temple is also known as "The Temple of the Sun God". The temple has two doors, eastern and western doors, along with a number of altars near it intended for offering sacrifices. The author believes that this temple is surrounded by a sanctuary, in which the visitors gather, then enter the temple from its eastern door and exit from its western door. The author also believes that this temple is the most notable place of worship discovered so far in the southeast Arabia. The author included an accurate architectural description of the temple, in addition to the surrounding altars, as well as documenting a number of archaeological discoveries that were found during excavation and archaeological surveys, such as: coins, stucco decorations on the walls of the temple, some Roman bronze artifacts such as the saddles, for example, stone statues of a bird likely to be an eagle. The book contains several photos, diagrams and drawings explaining its contents.
