and since then, there have been excavations in Amman, Pella, Gadara in Um Qais, Petra, Jerash, Kerak, and Aljun. Neolithic statuettes were found in 1983 at the site of prehistoric village Ain Ghazal. Fourth century mosaics have been found in the church at the Monument of Moses at Mount Nebo, and Byzantine mosaics at various churches in Nebo and Madaba. Other mosaics are found throughout the Jordanian desert at various castles dating back to the Umayyad dynasty. Such castles include Qasr al-Hallabat, Hmmam al-Sarakh, Qusayr ‘amra, Qasr Kharana, Mshatta, and Qasr al-Tuba. The Jordan Archaeological Museum was founded in 1951 in Amman, and archeological museums at Petra, jerash, Madaba, and Kerak have also come into existence. Archeological discoveries in Jordan have also been supported since 1970 by the American Center for Oriental Research (ACOR). ACOR hosts visiting archeologists and anthropologists, funds ongoing discovery initiatives and offers fellowships for students in the region. Society and customs Hospitality One of the key aspects of Jordanian culture is the hospitality shown by hosts to their guests. This is felt even while walking around the streets of Jordan, where the phrase "ahlan wa sahlan" ("I welcome you") is heard nearly everywhere you go. Old proverbs such as the following one show that traditions of hospitality date back many years: "The host must fear the guest. When he sits [and shares your food], he is company. When he stands [and leaves your house], he is a poet" (). Some of the traditions of hospitality come from Jordanian Bedouin culture. For example, the host and his/her guest often share a cup of black coffee. The host drinks out of the cup first, ensuring that the coffee is the right temperature. The guest then drinks what remains of the first cup. A second cup is served to the guest, and then a third. The host also serves the guest copious amounts of food and is careful to make sure the guest is comfortable and stays as long as he/she would like. Such displays are referred to as karam, the Arabic word for "generosity" or "hospitality" that also has implications of "nobility," "grace," and "refinement." In addition to wanting to be hospitable, the host also has a reputation at stake when inviting over a guest. Bedouin weddings Bedouin tradition favors marriage between first cousins on the paternal side of the family. This allows family property to stay within
