Ancient Greek religion encompasses the collection of beliefs, rituals, and mythology originating in ancient Greece in the form of both popular public religion and cult practices.
 These groups varied enough for it to be possible to speak of Greek religions or "cults" in the plural, though most of them shared similarities.
In ancient Greek religion, Kanathos (Greek: Κάναθος ) in the Argolid was the spring at Nauplia, where Hera annually renewed her virginity.
 There, Pausanias noted, was "a spring called Kanathos where, so say the Argives, Hera bathes every year and, by so doing, becomes a maiden; it is this story which is of the secrets connected with the rites which they perform to Hera."
 The unspoken nature of the ritual forbade its being embodied openly or directly in Greek mythology.
 S. Casson suggested that it was the obscure subject of the so-called "Ludovisi Throne", generally considered to represent the parallel, and far better-known, renewal of Aphrodite, bathing in the sea at Paphos.
The religious element is difficult to identify in Mycenaean Greece (c. 1600-1100 BC), especially as regards archaeological sites, where it remains problematic to pick out a place of worship with certainty.
 John Chadwick points out that at least six centuries lie between the earliest presence of Proto-Greek speakers in Hellas and the earliest inscriptions in the Mycenaean script known as Linear B, during which concepts and practices will have fused with indigenous beliefs, and—if cultural influences in material culture reflect influences in religious beliefs—with Minoan religion.
 As for these texts, the few lists of offerings that give names of gods as recipients of goods reveal nothing about religious practices, and there is no surviving literature.
 John Chadwick rejected a confusion of Minoan and Mycenaean religion derived from archaeological correlations and cautioned against "the attempt to uncover the prehistory of classical Greek religion by conjecturing its origins and guessing the meaning of its myths" above all through treacherous etymologies.
 Moses I. Finley detected very few authentic Mycenaean reflections in the eighth-century Homeric world, in spite of its "Mycenaean" setting.
 However, Nilsson asserts, based not on uncertain etymologies but on religious elements and on the representations and general function of the gods, that a lot of Minoan gods and religious conceptions were fused in the Mycenaean religion.
 From the existing evidence, it appears that the Mycenaean religion was the mother of the Greek religion.
 The Mycenaean pantheon already included many divinities that can be found in classical Greece.
A xoanon ( , Greek: ξόανον ; plural: ξόανα "xoana", from the verb ξέειν, "xeein", to carve or scrape [wood]) was an Archaic wooden cult image of Ancient Greece.
 Classical Greeks associated such cult objects, whether aniconic or effigy, with the legendary Daedalus.
 Many such cult images were preserved into historical times, though none are known to have survived to the modern day, except where their image was copied in stone or marble.
 In the 2nd century CE, Pausanias described numerous xoana in his "Description of Greece", notably the image of Hera in her temple at Samos.
 "The statue of Samian Hera, as Aethilos [sic!]
 says, was a wooden beam at first, but afterwards, when Prokles was ruler, it was humanized in form".
 In Pausanias' travels he never mentions seeing a xoanon of a mortal man.
The Theoi Project (also known as Theoi Greek Mythology) is a digital library website about Greek mythology and its representation in classical literature and ancient Greek art.
 It serves as a free reference to the gods ("theoi"), spirits ("daimones"), mythological creatures ("theres") and heroes of ancient Greek mythology and religion.
 Established in 2000, the website contains over 9,000 pages and 9,000 images.
 The website also has a library of classical literature on the theme of Greek mythology, including the works of many of the lesser-known poets.
Etruscan mythology comprises a set of stories, beliefs, and religious practices of the Etruscan civilization, originating in the 7th century BC from the preceding Iron Age Villanovan culture, with its influences in the mythology of ancient Greece and Phoenicia, and sharing similarities with concurrent Roman mythology.
 As the Etruscan civilization was assimilated into the Roman Republic in the 4th century BC, the Etruscan religion and mythology were partially incorporated into classical Roman culture, following the Roman tendency to absorb some of the local gods and customs of conquered lands.
In ancient Roman religion and myth, Nerio was an ancient war goddess and the personification of valor.
 She was the partner of Mars in ancient cult practices, and was sometimes identified with the goddess Bellona, and occasionally with the goddess Minerva.
 Spoils taken from enemies were sometimes dedicated to Nerio by the Romans.
 Nerio was later supplanted by mythologized deities appropriated and adapted from other religions.
The Heraion of Argos (Greek: Ἡραῖον Ἄργους ) is an ancient temple in Argos, Greece.
 It was part of the greatest sanctuary in the Argolid, dedicated to Hera, whose epithet "Argive Hera" (Ἥρη Ἀργείη "Here Argeie") appears in Homer's works.
 Hera herself claims to be the protector of Argos in "Iliad" IV, 50–52): "The three towns I love best are Argos, Sparta and Mycenae of the broad streets".
 The memory was preserved at Argos of an archaic, aniconic pillar representation of the Great Goddess.
 The site, which might mark the introduction of the cult of Hera in mainland Greece, lies northeast of Argos between the archaeological sites of Mycenae and Midea, two important Mycenaean cities.
 The traveller Pausanias, visiting the site in the 2nd century CE, referred to the area as Prosymna (Προσύμνη).
Greek mythology is the body of myths and teachings that belong to the ancient Greeks, concerning their gods and heroes, the nature of the world, and the origins and significance of their own cult and ritual practices.
 It was a part of the religion in ancient Greece.
 Modern scholars refer to and study the myths in an attempt to shed light on the religious and political institutions of ancient Greece and its civilization, and to gain understanding of the nature of myth-making itself.
Hera ( , ; Greek: Ἥρᾱ "Hērā", equivalently Ἥρη "Hērē", in Ionic and Homer) is the goddess of women and marriage in Greek mythology and religion.
 She is the daughter of the Titans Cronus and Rhea.
 Hera is married to her brother Zeus and is titled as the Queen of Heaven.
 One of her characteristics is her jealous and vengeful nature against Zeus's other lovers and offspring and against the mortals who cross her.
