Comparative mythology in the context of "Dogs in religion"

Proto-Indo-European mythology is the body of myths and deities associated with the Proto-Indo-Europeans, speakers of the hypothesized Proto-Indo-European language. Although the mythological motifs are not directly attested – since Proto-Indo-European speakers lived in preliterate societies – scholars of comparative mythology have reconstructed details from inherited similarities in mythological concepts found in Indo-European languages, based on the assumption that parts of the Proto-Indo-Europeans' original belief systems survived in the daughter traditions.

The Proto-Indo-European pantheon includes a number of securely reconstructed deities, since they are both cognates—linguistic siblings from a common origin—and associated with similar attributes and body of myths: such as *Dyḗws Ph₂tḗr, the daylight-sky god; his consort *Dʰéǵʰōm, the earth mother; his daughter *H₂éwsōs, the dawn goddess; his sons the Divine Twins; and *Seh₂ul and *Meh₁not, a solar deity and moon deity, respectively. Some deities, like the weather god *Perkʷunos or the herding-god *Péh₂usōn, are only attested in a limited number of traditions—Western (i.e. European) and Graeco-Aryan, respectively—and could therefore represent late additions that did not spread throughout the various Indo-European dialects.

The aegis (/ˈiːdʒɪs/ EE-jis; Ancient Greek: αἰγίς aigís), as stated in the Iliad, is a device carried by Athena and Zeus, variously interpreted as an animal skin or a shield and sometimes featuring the head of a Gorgon. There may be a connection with a deity named Aex, a daughter of Helios and a nurse of Zeus or alternatively a mistress of Zeus (Hyginus, Astronomica 2. 13).

The modern concept of doing something "under someone's aegis" means doing something under the protection of a powerful, knowledgeable, or benevolent source. The word aegis is identified with protection by a strong force with its roots in Greek mythology and adopted by the Romans; there are parallels in Norse mythology and in Egyptian mythology as well, where the Greek word aegis is applied by extension.

Interpretatio graeca (Latin for 'Greek translation'), or "interpretation by means of Greek [models]", refers to the tendency of the ancient Greeks to identify foreign deities with their own gods. It is a discourse used to interpret or attempt to understand the mythology and religion of other cultures; a comparative methodology using ancient Greek religious concepts and practices, deities, and myths, equivalencies, and shared characteristics.

The phrase may describe Greek efforts to explain others' beliefs and myths, as when Herodotus describes Egyptian religion in terms of perceived Greek analogues, or when Dionysius of Halicarnassus and Plutarch document Roman cults, temples, and practices under the names of equivalent Greek deities. Interpretatio graeca may also describe non-Greeks' interpretation of their own belief systems by comparison or assimilation with Greek models, as when Romans adapt Greek myths and iconography under the names of their own gods.

The Divine Twins are youthful horsemen, either gods or demigods, who serve as rescuers and healers in Proto-Indo-European mythology.

Like other Proto-Indo-European divinities, the Divine Twins are not directly attested by archaeological or written materials, but scholars of comparative mythology and Indo-European studies generally agree on the motifs they have reconstructed by way of the comparative method.

In comparative mythology, sky father is a term for a recurring concept in polytheistic religions of a sky god who is addressed as a "father", often the father of a pantheon and is often either a reigning or former King of the Gods. The concept of "sky father" may also be taken to include Sun gods with similar characteristics, such as Ra. The concept is complementary to an "earth mother".

"Sky Father" is a direct translation of the Vedic Dyaus Pita, etymologically descended from the same Proto-Indo-European deity name as the Greek Zeûs Pater and Roman Jupiter, all of which are reflexes of the same Proto-Indo-European deity's name, *Dyēus Ph₂tḗr. While there are numerous parallels adduced from outside of Indo-European mythology, there are exceptions (e.g. In Egyptian mythology, Nut is the sky mother and Geb is the earth father).

A dying-and-rising god, life–death–rebirth deity, or resurrection deity is a religious motif in which a god or goddess dies and is resurrected. Examples of gods who die and later return to life are most often cited from the religions of the ancient Near East. The traditions influenced by them include the Greco-Roman mythology.The concept of a dying-and-rising god was first proposed in comparative mythology by James Frazer's seminal The Golden Bough (1890). Frazer associated the motif with fertility rites surrounding the yearly cycle of vegetation. Frazer cited the examples of Osiris, Tammuz, Adonis and Attis, Zagreus, Dionysus, and Jesus.

Frazer's interpretation of the category has been critically discussed in 20th-century scholarship, to the conclusion that many examples from the world's mythologies included by Frazer under "dying and rising" should only be considered "dying" but not "rising", and that the genuine dying-and-rising god is a characteristic feature of ancient Near Eastern mythologies and the derived mystery cults of late antiquity. "Death or departure of the gods" is motif A192 in Stith Thompson's Motif-Index of Folk-Literature (1932), and "resurrection of gods" is motif A193.

In astronomy, axis mundi is the Latin term for the axis of Earth between the celestial poles. In a geocentric coordinate system, this is the axis of rotation of the celestial sphere. Consequently, in ancient Greco-Roman astronomy, the axis mundi is the axis of rotation of the planetary spheres within the classical geocentric model of the cosmos.

In 20th-century comparative mythology, the term axis mundi – also called the cosmic axis, world axis, world pillar, center of the world, or world tree – has been greatly extended to refer to any mythological concept representing "the connection between Heaven and Earth" or the "higher and lower realms". Mircea Eliade introduced the concept in the 1950s. Axis mundi closely relates to the mythological concept of the omphalos (navel) of the world or cosmos.Items presented as examples of the axis mundi by comparative mythologists include plants (notably a tree but also other types of plants such as a vine or stalk), a mountain, a column of smoke or fire, or a product of human manufacture (such as a staff, a tower, a ladder, a staircase, a maypole, a cross, a steeple, a rope, a totem pole, a pillar, a spire). Its proximity to heaven may carry implications that are chiefly religious (pagoda, Temple Mount, minaret, church) or secular (obelisk, lighthouse, rocket, skyscraper). The image appears in religious and secular contexts. The axis mundi symbol may be found in cultures utilizing shamanic practices or animist belief systems, in major world religions, and in technologically advanced "urban centers". In Mircea Eliade's opinion: "Every Microcosm, every inhabited region, has a Centre; that is to say, a place that is sacred above all."
