Amenemhat II
Under Amenemhat II several mining expeditions are known: at least 3 in the Sinai, one in the Wadi Gasus (year 28) and one in search for amethysts in the Wadi el-Hudi. He is known to have ordered building works at Heliopolis, Herakleopolis, Memphis, in the Eastern Delta, and rebuilt a ruined temple at Hermopolis. There are some mentions of the building of a "First temple" but it is still unclear what it should have been. A well-known finding associated with Amenemhat II is the Great Sphinx of Tanis (Louvre A23), later usurped by many other pharaohs. He is also named on the boxes of a treasure of silver objects found under the temple of Montu at Tod: notably, many of these objects are not of Egyptian workmanship but rather Aegean, evidencing contacts between Egypt and foreign civilizations in the Middle Kingdom. Many private stelae bears Amenemhat's cartouches – and sometimes even his regnal years – but are of little help in providing useful information about the events of his reign.
