title: Hellenistic period
paragraph_text: Ptolemy's family ruled Egypt until the Roman conquest of 30 BC. All the male rulers of the dynasty took the name Ptolemy. Ptolemaic queens, some of whom were the sisters of their husbands, were usually called Cleopatra, Arsinoe or Berenice. The most famous member of the line was the last queen, Cleopatra VII, known for her role in the Roman political battles between Julius Caesar and Pompey, and later between Octavian and Mark Antony. Her suicide at the conquest by Rome marked the end of Ptolemaic rule in Egypt though Hellenistic culture continued to thrive in Egypt throughout the Roman and Byzantine periods until the Muslim conquest.
title: Egypt
paragraph_text: Egypt has one of the longest histories of any modern country, arising in the tenth millennium BC as one of the world's first nation states. Considered a cradle of civilisation, Ancient Egypt experienced some of the earliest developments of writing, agriculture, urbanisation, organised religion and central government. Iconic monuments such as the Giza Necropolis and its Great Sphinx, as well the ruins of Memphis, Thebes, Karnak, and the Valley of the Kings, reflect this legacy and remain a significant focus of archaeological study and popular interest worldwide. Egypt's rich cultural heritage is an integral part of its national identity, having endured, and at times assimilated, various foreign influences, including Greek, Persian, Roman, Arab, Ottoman, and European. Although Christianised in the first century of the Common Era, it was subsequently Islamised due to the Islamic conquests of the seventh century.

Ancient Egyptian obelisks, constructed about 3500 BC, are also among the earliest shadow clocks.

title: Hellenistic period
paragraph_text: The worship of dynastic ruler cults was also a feature of this period, most notably in Egypt, where the Ptolemies adopted earlier Pharaonic practice, and established themselves as god-kings. These cults were usually associated with a specific temple in honor of the ruler such as the Ptolemaieia at Alexandria and had their own festivals and theatrical performances. The setting up of ruler cults was more based on the systematized honors offered to the kings (sacrifice, proskynesis, statues, altars, hymns) which put them on par with the gods (isotheism) than on actual belief of their divine nature. According to Peter Green, these cults did not produce genuine belief of the divinity of rulers among the Greeks and Macedonians. The worship of Alexander was also popular, as in the long lived cult at Erythrae and of course, at Alexandria, where his tomb was located.

title: Mark Lehner
paragraph_text: Mark Lehner is an American archaeologist with more than 30 years of experience excavating in Egypt. He was born in North Dakota in 1950. His approach, as director of Ancient Egypt Research Associates (AERA), is to conduct interdisciplinary archaeological investigation. Every excavated object is examined by specialists to create an overall picture of an archaeological site—from the buildings down to the pollen spores. His international team currently runs the Giza Plateau Mapping Project, excavating and mapping the ancient city of the builders of the Giza pyramid complex, which dates to the fourth dynasty of Egypt. He discovered that Pyramid G1-a, one of the subsidiary pyramids of the Great Pyramid, belonged to Hetepheres I; it was originally thought to belong to Queen Meritites I.
title: Green
paragraph_text: For the ancient Egyptians, green had very positive associations. The hieroglyph for green represented a growing papyrus sprout, showing the close connection between green, vegetation, vigor and growth. In wall paintings, the ruler of the underworld, Osiris, was typically portrayed with a green face, because green was the symbol of good health and rebirth. Palettes of green facial makeup, made with malachite, were found in tombs. It was worn by both the living and dead, particularly around the eyes, to protect them from evil. Tombs also often contained small green amulets in the shape of scarab beetles made of malachite, which would protect and give vigor to the deceased. It also symbolized the sea, which was called the "Very Green."

title: Hapi (Son of Horus)
paragraph_text: Hapi, sometimes transliterated as Hapy, is one of the Four sons of Horus in ancient Egyptian religion, depicted in funerary literature as protecting the throne of Osiris in the Underworld. Hapi was the son of Heru-ur and Isis or Serqet. He is not to be confused with another god of the same name. He is commonly depicted with the head of a hamadryas baboon, and is tasked with protecting the lungs of the deceased, hence the common depiction of a hamadryas baboon head sculpted as the lid of the canopic jar that held the lungs. Hapi is in turn protected by the goddess Nephthys. When his image appears on the side of a coffin, he is usually aligned with the side intended to face north. When embalming practices changed during the Third Intermediate Period and the mummified organs were placed back inside the body, an amulet of Hapi would be included in the body cavity.
