full_context: Document 1: Guardians of the directions: The Guardians of the Directions (Sanskrit: दिक्पाल, Dikpāla) are the deities who rule the specific directions of space according to Hinduism and "Vajrayāna" Buddhism—especially Kālacakra . As a group of eight deities, they are called Aṣṭa-Dikpāla (अष्ट-दिक्पाल), literally meaning guardians of eight directions. They are often augmented with two extra deities for the ten directions (the two extra directions being zenith and nadir), when they are known as the Daśa-Dikpāla . In Hinduism it is traditional to represent their images on the walls and ceilings of Hindu temples. Ancient Java and Bali Hinduism recognize Nava-Dikpāla , literally meaning guardians of nine directions, that consist of eight directions with one addition in the center. The nine guardian gods of directions is called "Dewata Nawa Sanga" (Nine guardian devata). The diagram of these guardian gods of directions is featured in Surya Majapahit, the emblem of Majapahit empire.
Document 2: Perkūnas: Perkūnas (Lithuanian: "Perkūnas" , Latvian: "Pērkons" or "Pērkon", Old Prussian: "Perkūns", Yotvingian: "Parkuns") was the common Baltic god of thunder, one of the most important deities in the Baltic pantheon.

Document 3: Uranus (mythology): Uranus ( or ; Ancient Greek Οὐρανός , Ouranos meaning "sky" or "heaven") was the primal Greek god personifying the sky. His name in Roman mythology was Caelus. In Ancient Greek literature, Uranus or Father Sky was the son and husband of Gaia, Mother Earth. According to Hesiod's "Theogony", Uranus was conceived by Gaia alone, but other sources cite Aether as his father. Uranus and Gaia were the parents of the first generation of Titans, and the ancestors of most of the Greek gods, but no cult addressed directly to Uranus survived into Classical times, and Uranus does not appear among the usual themes of Greek painted pottery. Elemental Earth, Sky and Styx might be joined, however, in a solemn invocation in Homeric epic.

He was the son of Tros of Dardania, from whose name "Troy" was supposedly derived, and of Callirrhoe, the daughter of the river god Scamander. His brothers were Ilus and Assaracus. In one version of the myth, he is abducted by Zeus, in the form of an eagle, to serve as cup-bearer in Olympus. Homer describes Ganymede as the most beautiful of mortals:

According to Hinduism and Hindu mythology, Kshetrapala, that is, the lord of the farmland, is a deity who was originally a deity of the farmland, particularly in the south India. Over a period of time, Kshetrapala became a generic name applied to deities associated with a piece or parcel of land, or a particular region (kshetra in Sanskrit).

Document 10: Prajapati: Prajapati (IAST: "Prajāpati-Rajjan or Rajanya ", "lord of creatures and protector") is a Vedic deity of Hinduism. The term also connotes many different gods, depending on the Hindu text, ranging from being the creator god to being same as one of the following: Brahma, Vishnu, Shiva, Agni, Indra, Vishvakarma, Bharata, Kapila and many others. According to George Williams, the inconsistent, varying and evolving Prajapati concept in Hindu mythology reflects the diverse Hindu cosmology. In classical and medieval era literature, Prajapati is equated to the metaphysical concept called Brahm as Prajapati-Brahm (Svayambhu Brahm), or alternatively Brahm is described as one who existed before Prajapati.
Document 11: List of thunder gods: Polytheistic peoples of many cultures have postulated a thunder god, the personification or source of the forces of thunder and lightning; a lightning god does not have a typical depiction, and will vary based on the culture. In Indo-European cultures, the thunder god is frequently known as the chief or king of the gods, e.g. Indra in Hinduism, Zeus in Greek mythology, and Perun in ancient Slavic religion; or a close relation thereof, e.g. Thor, son of Odin, in Norse mythology. This is also true of Shango in Yoruba religion and in the syncretic religions of the African Diaspora, such as Santería (Cuba, Puerto Rico, United States and Candomblé (Brazil).
Document 12: Dionysus in comparative mythology: Dionysus, the god of wine, theatre, and ecstasy in ancient Greek religion, has been compared to many other deities, both by his classical worshippers and later scholars.

Document 13: Varuna: Varuna ( ; IAST: "Varuṇa " वरुण , Malay: "Baruna") is a Vedic deity associated first with sky, later with waters as well as with Ṛta (justice) and Satya (truth). He is found in the oldest layer of Vedic literature of Hinduism, such as the hymn 7.86 of the "Rigveda". He is possibly one of the earliest Indo-Aryan triads with parallels to a Avestan deity, possibly Iranian Ahura Mazda. His streak of demonic violent tendencies, according to Hindu mythology, led to his demotion and Indra taking away most of his powers.
Document 14: Altis: The Altis (Greek: Ἄλτις) also referred to as the sanctuary to the gods, is the name of a location most well known for being a place of significant religious importance to the Ancient Greeks, considered to be a sacred precinct that was constructed and used from around 776 BCE to fourth century BCE and used for the worship of several Greek gods and goddesses. Though the architects are not definitively known, it is generally attributed to be partially the work of Libon of Elis. Located in the wide valley of the Alfeiós River (also Romanized as Alpheus, Alpheios) in the western part of Peloponnesus, around 18 kilometers away from the Ionian Sea, the name Altis was derived from a corruption of the Elean word alsos meaning “the grove” because the area was thickly wooded with oaks, plane trees, poplars, and olives. The structure itself was an irregular quadrangular area more than 200 yards (183 meters) on each side and walled except to the North where it was bounded by the Kronion (Mount Kronos). Inside were sanctuaries, the centers of religious worship, where the Greeks built over 70 temples, treasuries, altars, statues, and other structures in dedication to their gods. The site was continuously inhabited from Mycenaean times until the 6th century BCE, where cult activity apparently first began at the foot of the hill of Kronos where altars to the goddesses Rhea, Gaia, and Eileithyia have left their traces. Some other cults found here were devoted to figures like the hero cult of Pelops and Hippodameia (arguably the oldest shrine there) important mythological figures that are generally known for the founding myth of the Olympic Games. During the time of the Dorian Invasion settlers from northwestern Greece inhabited the Altis whereby they introduced the worship of two major Greek deities in the Greek pantheon Hera and Zeus as well as constructing the most memorable things there, the Sanctuary and altar of Zeus, where to this day the ruins of the two principal temples: the Temple of Hera (6th century BCE) and the Temple of Zeus (5th century BCE) still remain. Throughout Antiquity this Temple was considered the most perfect example of the Doric order. This sanctuary also contained one of the highest concentrations of masterpieces of the ancient Mediterranean world though many have since been lost. In connection with the cult of Zeus the Altis was then given the name Olympia, with famous Olympia, Greece being built on this site where also the first Olympic Games took place here, once every four years.
Document 15: Oceanus: Oceanus ( ; Greek: Ὠκεανός "Ōkeanós", ] ), also known as Ogenus ("Ogenos", Ωγηνος) or Ogen (Ωγην), was a divine figure in classical antiquity, believed by the ancient Greeks and Romans to be the divine personification of the sea, an enormous river encircling the world.
