First Yemen expedition
Phillips's next expedition was in 1951 to the Arabian peninsula. Planning for this expedition began with a 1949 meeting between Phillips and Ahmad bin Yahya Hamidaddin, then King of Yemen, who suggested to Phillips that he explore a region of modern-day Yemen. The Imam's recommendation was further reinforced in meetings that Phillips had with Arabist St John Philby and with Charles Inge who was then Director of Antiquities for the Crown Colony of Aden. These conversations culminated in Phillips leading a journey to explore the ancient city of Timna. This region is historically significant because of its role in the incense trade route. As preparation for the Yemeni expedition, Phillips conducted a two-week aerial reconnaissance of the Arabian peninsula.
The expedition to Yemen was smaller and more tightly organized than Phillips's African trip. It included William F. Albright as chief archaeologist. In addition to Timna, the expedition also focused on excavation of Ma'rib, believed to be the capital of the Sabaʾ empire, historically identified with the biblical Queen of Sheba.
At Timna, Phillips's team excavated through layers of strata, allowing them to develop a timeline of the city dating to the 8th century BCE. An excavation at the House Yafash uncovered twin bronze lions and an alabaster figurine referred to by the team as "Miriam". The excavation also uncovered many utilitarian objects from daily life and funerary objects from a cemetery at Timna. One of the excavation sites was the Circular Moon Temple, dating to approximately 800 BCE.
Part of the expedition took place at a pre-Islamic site called Hajar bin Humeid, where excavation reached layers of strata from the 11th century BCE. Also noteworthy from the 1951 endeavors was the discovery of ancient masonry marks on paving stones providing instructions for builders. This find served as a key to the language of the ancient inhabitants. Also included was epigraphist Albert Jamme who contributed significantly to understanding the language and developing the timeline of the ancient people of the region. Jamme compiled his findings in a treatise Sabaean Inscriptions From Mahram Bilqis (Marib), which included a foreword by Phillips.
Excavations included the Marib Dam, which was the largest of ancient times, and the Awwam Temple, which was one of the most important temples of the Sabean people, in use 1,200 years before the emergence of Islam. The team developed a detailed description of the temple, including its size and materials of construction, and determined that the temple was reconstructed at least once during these pre-Islamic times. They discovered many inscriptions within these structures that provided insight into the pre-Islamic religion of the region. The expedition team also found a Hellenistic influence in certain of the statues in the temple.
However, the expedition was interrupted by raids by Bedouin warriors. The size of the project, the taking of artifacts, and the lack of familiarity of the local people with foreigners caused suspicion from locals, with some viewing Phillips's expedition as an invasion. Early in the project, Phillips was briefly taken prisoner by the locals. By early 1952, the hostility was enough to end the project, and the region has remained closed to archaeologists since that time.
