Helios in the context of "Solar deity"

Rhodes (/roʊdz/ ; Greek: Ρόδος, romanized: Ródos [ˈroðos]) is the largest of Greece's Dodecanese islands and their historical capital; it is the ninth largest island in the Mediterranean Sea. Administratively, Rhodes constitutes a separate municipality within the Rhodes regional unit, which is part of the South Aegean administrative region. The principal town of the island and seat of the municipality is the city of Rhodes, home to its 50,636 inhabitants according to its 2011 census. By 2022, the island’s population had grown to 125,113 people. Located northeast of Crete and southeast of Athens, Rhodes is often referred to by several nicknames: the "Island of the Sun" after its patron sun god Helios; "The Pearl Island"; and "The Island of the Knights", a reference to the Knights of Saint John of Jerusalem, who ruled the island from 1310 to 1522.

Historically, Rhodes was famous for the Colossus of Rhodes, one of the Seven Wonders of the Ancient World. The Medieval Old Town of the City of Rhodes has been declared a World Heritage Site. During the early 21st century the island was one of the most popular tourist destinations in Europe.

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.

The Colossus of Rhodes (Ancient Greek: ὁ Κολοσσὸς Ῥόδιος, romanized: ho Kolossòs Rhódios; Modern Greek: Κολοσσός της Ρόδου, romanized: Kolossós tis Ródou) was a statue of the Greek sun god Helios, erected in the city of Rhodes, on the Greek island of the same name, by Chares of Lindos in 280 BC. One of the Seven Wonders of the Ancient World, it was constructed to celebrate the successful defence of Rhodes against an attack by Demetrius I of Macedon, who had besieged it for a year with a large army and navy.

According to most contemporary descriptions, the Colossus stood approximately 70 cubits, or 33 metres (108 feet) high – approximately two-thirds of the height of the modern Statue of Liberty from feet to crown – making it the tallest statue in the ancient world. It collapsed during the earthquake of 226 BC, although parts of it were preserved. In accordance with the Oracle of Delphi, the Rhodians did not rebuild it. John Malalas wrote that Hadrian in his reign re-erected the Colossus, but he was mistaken. According to the Suda, the Rhodians were called Colossaeans (Κολοσσαεῖς), because they erected the statue on the island.

Tílos (Greek: Τήλος; Ancient Greek: Τῆλος, romanized: Telos) is a small Greek island and municipality located in the Aegean Sea. It is part of the Dodecanese group of islands, and lies midway between Kos and Rhodes. In 2021, the island had a population of 746 people. Along with the uninhabited offshore islets of Antitilos and Gaidaros, it forms the Municipality of Tilos, which has a total land area of 64.525 square kilometres (24.913 sq mi). Tilos is part of the Rhodes regional unit.

Popularly, Telos was the son of Helios and Halia, the sister of the Telchines. He came to the island in search of herbs to heal his ill mother, and later returned to found a temple to Apollo and Neptune. However, Telos (Telo or Tilo) does not appear in Greek mythology and the name probably has an unknown pre-Hellenic origin. Pliny the Elder notes that in antiquity Telos was known as Agathussa (Αγαθούσσα) (also Agathusa and Agathousa). In the Middle Ages, it was known by the Italian as Episcopio, either because it was a Bishop Seat or because its position as Vantage Point. The island has also been called in Turkish İlyaki and in modern Italian Piscopi.

Jason (/ˈdʒeɪ.sən/ JAY-sən; Ancient Greek: Ἰάσων, romanized: Iásōn [i.ǎːsɔːn]) was an ancient Greek mythological hero and leader of the Argonauts, whose quest for the Golden Fleece is featured in Greek literature. He was the son of Aeson, the rightful king of Iolcos. He was married to the sorceress Medea, the granddaughter of the sungod Helios.

Jason appeared in various literary works in the classical world of Greece and Rome, including the epic poem Argonautica and the tragedy Medea. In the modern world, Jason has emerged as a character in various adaptations of his myths, such as the 1963 film Jason and the Argonauts and the 2000 TV miniseries of the same name.

In Greek mythology, the Titans (Ancient Greek: Τιτᾶνες, Tītânes; singular: Τιτάν, Tītā́n) were the deities that preceded the Olympians. According to the Theogony of Hesiod, they were the twelve children of the primordial deities Uranus (Sky) and Gaia (Earth). The six male Titans were Oceanus, Coeus, Crius, Hyperion, Iapetus, and Cronus, and the six female Titans (called the Titanesses; Ancient Greek: Τιτανίδες, Tītānídes; singular: Τιτανίς, Tītānís) were Theia, Rhea, Themis, Mnemosyne, Phoebe, and Tethys.

After Cronus married his sister Rhea, she bore the first generation of Olympians: the six siblings Zeus, Hera, Poseidon, Demeter, Hades, and Hestia. Certain other children of the Titans, such as Prometheus, Atlas, Helios, and Leto, are sometimes also called Titans.

In ancient Greek mythology and religion, Selene (/sɪˈliːniː/; Ancient Greek: Σελήνη pronounced [selɛ̌ːnɛː] seh-LEH-neh) is the goddess and personification of the Moon. Also known as Mene (/ˈmiːniː/; Ancient Greek: μήνη pronounced [mɛ̌ː.nɛː] MEH-neh), she is traditionally the daughter of the Titans Hyperion and Theia, and sister of the sun god Helios and the dawn goddess Eos. She drives her moon chariot across the heavens. Several lovers are attributed to her in various myths, including Zeus, Pan, her brother Helios and the mortal Endymion. In post-classical times, Selene was often identified with Artemis, much as her brother, Helios, was identified with Apollo. Selene and Artemis were also associated with Hecate and all three were regarded as moon and lunar goddesses, but only Selene was regarded as the personification of the Moon itself.

Her equivalent in Roman religion and mythology is the goddess Luna.

Helium (from Greek: ἥλιος, romanized: helios, lit. 'sun') is a chemical element; it has symbol He and atomic number 2. It is a colorless, odorless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements, and it does not have a melting point at standard pressures. It is the second-lightest and second-most abundant element in the observable universe, after hydrogen. It is present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this in both the Sun and Jupiter, because of the very high nuclear binding energy (per nucleon) of helium-4 with respect to the next three elements after helium. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. The most common isotope of helium in the universe is helium-4, the vast majority of which was formed during the Big Bang. Large amounts of new helium are created by nuclear fusion of hydrogen in stars.

Helium was first detected as an unknown, yellow spectral line signature in sunlight during a solar eclipse in 1868 by Georges Rayet, Captain C. T. Haig, Norman R. Pogson, and Lieutenant John Herschel, and was subsequently confirmed by French astronomer Jules Janssen. Janssen is often jointly credited with detecting the element, along with Norman Lockyer. Janssen recorded the helium spectral line during the solar eclipse of 1868, while Lockyer observed it from Britain. However, only Lockyer proposed that the line was due to a new element, which he named after the Sun. The formal discovery of the element was made in 1895 by chemists Sir William Ramsay, Per Teodor Cleve, and Nils Abraham Langlet, who found helium emanating from the uranium ore cleveite, which is now not regarded as a separate mineral species, but as a variety of uraninite. In 1903, large reserves of helium were found in natural gas fields in parts of the United States, by far the largest supplier of the gas today.
