materials, sent from King Hiram of Tyre. After the completion of the temple, Solomon is described in the biblical narrative as erecting many other buildings of importance in Jerusalem. For 13 years, he was engaged in the building of a royal palace on Ophel (a hilly promontory in central Jerusalem). This complex included buildings referred to as: The House (or Hall) of the Forest of Lebanon The Hall or Porch of Pillars The Hall of the Throne or the Hall of Justice as well as his own residence and a residence for his wife, Pharaoh's daughter. Solomon's throne is said to have been spectacularly opulent and possessed moving parts, making it one of the earliest mechanical devices in history. Solomon also constructed great water works for the city, and the Millo (Septuagint, Acra) for the defense of the city. However, excavations of Jerusalem have discovered no monumental architecture from the era, and no remains of either the Temple or Solomon's palace have been found. Solomon is also described as rebuilding cities elsewhere in Israel, creating the port of Ezion-Geber, and constructing Palmyra in the wilderness as a commercial depot and military outpost. Although the location of the port of Ezion-Geber is known, no remains have ever been found. More archaeological success has been achieved with the major cities Solomon is said to have strengthened or rebuilt, for example, Hazor, Megiddo and Gezer. These all have substantial ancient remains, including impressive six-chambered gates, and ashlar palaces; however it is no longer the scholarly consensus that these structures date to the time, according to the Bible, when Solomon ruled. According to the Bible, during Solomon's reign, Israel enjoyed great commercial prosperity, with extensive traffic being carried on by land with Tyre, Egypt, and Arabia, and by sea with Tarshish, Ophir, and South India. Wives and concubines According to the biblical account, Solomon had 700 wives and 300 concubines. The wives were described as foreign princesses, including Pharaoh's daughter and women of Moab, Ammon, Edom, Sidon and of the Hittites. His marriage to Pharaoh's daughter appears to have cemented a political alliance with Egypt, whereas he clung to his other wives and concubines "in love". The only wife mentioned by name is Naamah the Ammonite, mother of Solomon's successor, Rehoboam. The biblical narrative notes with disapproval that Solomon permitted his foreign wives to import their national deities, building temples to Ashtoreth and Milcom.
