The afterlife played an important role in Ancient Egyptian religion, and its belief system is one of the earliest known in recorded history. When the body died, parts of its soul known as ka (body double) and the ba (personality) would go to the Kingdom of the Dead. While the soul dwelt in the Fields of Aaru, Osiris demanded work as restitution for the protection he provided. Statues were placed in the tombs to serve as substitutes for the deceased.
Arriving at one's reward in afterlife was a demanding ordeal, requiring a sin-free heart and the ability to recite the spells, passwords and formulae of the Book of the Dead. In the Hall of Two Truths, the deceased's heart was weighed against the Shu feather of truth and justice taken from the headdress of the goddess Ma'at. If the heart was lighter than the feather, they could pass on, but if it were heavier they would be devoured by the demon Ammit.
Egyptians also believed that being mummified and put in a sarcophagus (an ancient Egyptian "coffin" carved with complex symbols and designs, as well as pictures and hieroglyphs) was the only way to have an afterlife. What are referred to as the Coffin Texts, are inscribed on a coffin and serve as a guide for the challenges in the afterlife. The Coffin texts are more or less a duplication of the Pyramid Texts, which would serve as a guide for Egyptian pharaohs or queens in the afterlife. Only if the corpse had been properly embalmed and entombed in a mastaba, could the dead live again in the Fields of Yalu and accompany the Sun on its daily ride. Due to the dangers the afterlife posed, the Book of the Dead was placed in the tomb with the body as well as food, jewelry, and 'curses'. They also used the "opening of the mouth".
Ancient Egyptian civilization was based on religion; their belief in the rebirth after death became the driving force behind their funeral practices. Death was simply a temporary interruption, rather than complete cessation, of life, and that eternal life could be ensured by means like piety to the gods, preservation of the physical form through mummification, and the provision of statuary and other funerary equipment. Each human consisted of the physical body, the ka, the ba, and the akh. The Name and Shadow were also living entities. To enjoy the afterlife, all these elements had to be sustained and protected from harm.
On 30 March 2010, a spokesman for the Egyptian Culture Ministry claimed it had unearthed a large red granite door in Luxor with inscriptions by User, a powerful adviser to the 18th Dynasty Queen Hatshepsut who ruled between 1479 BC and 1458 BC, the longest of any woman. It believes the false door is a 'door to the Afterlife'. According to the archaeologists, the door was reused in a structure in Roman Egypt.
The Greek god Hades is known in Greek mythology as the king of the underworld, a place where souls live after death. The Greek god Hermes, the messenger of the gods, would take the dead soul of a person to the underworld (sometimes called Hades or the House of Hades). Hermes would leave the soul on the banks of the River Styx, the river between life and death.
Charon, also known as the ferry-man, would take the soul across the river to Hades, if the soul had gold: Upon burial, the family of the dead soul would put coins under the deceased's tongue. Once crossed, the soul would be judged by Aeacus, Rhadamanthus and King Minos. The soul would be sent to Elysium, Tartarus, or Asphodel Fields. The Elysian Fields were for the ones that lived pure lives. It consisted of green fields, valleys and mountains, everyone there was peaceful and contented, and the Sun always shone there. Tartarus was for the people that blasphemed against the gods, or were simply rebellious and consciously evil.
The Asphodel Fields were for a varied selection of human souls: Those whose sins equalled their goodness, were indecisive in their lives, or were not judged. Those who had sinned went to the deepest pit, Tartarus. In Tartarus, the soul would be punished by being burned in lava, or stretched on racks. Some heroes of Greek legend are allowed to visit the underworld. The Romans had a similar belief system about the afterlife, with Hades becoming known as Pluto. In the ancient Greek myth about the Labours of Heracles, the hero Heracles had to travel to the underworld to capture Cerberus, the three-headed guard dog, as one of his tasks.
In Dream of Scipio, Cicero describes what seems to be an out of body experience, of the soul traveling high above the Earth, looking down at the small planet, from far away.
In Book VI of Virgil's Aeneid, the hero, Aeneas, travels to the underworld to see his father. By the River Styx, he sees the souls of those not given a proper burial, forced to wait by the river until someone buries them. While down there, along with the dead, he is shown the place where the wrongly convicted reside, the fields of sorrow where those who committed suicide and now regret it reside, including Aeneas' former lover, the warriors and shades, Tartarus (where the titans and powerful non-mortal enemies of the Olympians reside) where he can hear the groans of the imprisoned, the palace of Pluto, and the fields of Elysium where the descendants of the divine and bravest heroes reside. He sees the river of forgetfulness, Lethe, which the dead must drink to forget their life and begin anew. Lastly, his father shows him all of the future heroes of Rome who will live if Aeneas fulfills his destiny in founding the city.
The Poetic and Prose Eddas, the oldest sources for information on the Norse concept of the afterlife, vary in their description of the several realms that are described as falling under this topic. The most well-known are:
Hel: (lit. "The Covered Hall")
Niflhel: (lit. "The Dark" or "Misty Hel")
