Castor and Pollux in the context of "Phoebe (mythology)"

Helen (Ancient Greek: Ἑλένη, romanized: Helénē), also known as Helen of Troy, or Helen of Sparta, and in Latin as Helena, was a figure in Greek mythology said to have been the most beautiful woman in the world. She was believed to have been the daughter of Zeus by Leda or Nemesis, and the sister of Clytemnestra, Castor, Pollux, Philonoe, Phoebe and Timandra. She was first married to King Menelaus of Sparta "who became by her the father of Hermione, and, according to others, of Nicostratus also." Her subsequent marriage to Paris of Troy was the most immediate cause of the Trojan War.

Elements of her putative biography come from ancient Greek and Roman authors such as Homer, Hesiod, Euripides, Virgil and Ovid. In her youth, she was abducted by Theseus. A competition between her suitors for her hand in marriage saw Menelaus emerge victorious. All of her suitors were required to swear an oath (known as the Oath of Tyndareus) promising to provide military assistance to the winning suitor, if Helen were ever stolen from him. The obligations of the oath precipitated the Trojan War. When she married Menelaus she was still very young. In most accounts, including Homer's, Helen ultimately fell in love with Paris and willingly went to Troy with him, though there are also stories in which she was abducted.

Regillus was an ancient lake of Latium, Italy, famous in the legendary history of Rome as the lake near which the Battle of Lake Regillus took place in 496 B.C. between the Romans and the Latins which finally decided the hegemony of Rome in Latium. The lake, now drained, was near the present-day town of Frascati.

During the battle, so the story runs, the Roman dictator Postumius vowed to build a temple to the twin gods Castor and Pollux, who were specially venerated in Tusculum, the chief city of the Latins (it being a Roman custom to invoke the aid of the gods of the enemy). The pair duly appeared during the battle dressed in white armour riding white horses, helped the Romans to prevail, and afterwards took the news of the victory to Rome. There they watered their horses at the spring of Juturna, close to which their temple in the Forum was subsequently erected.

Twins in mythology are in many cultures around the world. In some cultures they are seen as ominous, and in others they are seen as auspicious. Twins in mythology are often cast as two halves of the same whole, sharing a bond deeper than that of ordinary siblings, or seen as fierce rivals. They can be seen as representations of a dualistic worldview. They can represent another aspect of the self, a doppelgänger, or a shadow.

Twins are often depicted with special powers. This applies to both mortal and immortal sets of twins, and often is related to power over the weather. Twins in mythology also often share deep bonds. In Greek mythology, Castor and Pollux share a bond so strong that when mortal Castor dies, Pollux gives up half of his immortality to be with his brother. Castor and Pollux are the Dioscuri twin brothers. Their mother is Leda, a being who was seduced by Zeus who had taken the form of a swan. Even though the brothers are twins, they have two different fathers. This phenomenon is a very common interpretation of twin births across different mythological cultures. Castor's father is Tyndareus, the king of Sparta (hence the mortal form). Pollux is the son of Zeus (demigod). This brothers were said to be born from an egg along with either sister Helen and Clytemnestra. This teleologically explains why their constellation, the Dioskouroi or Gemini, is only seen during one half of the year, as the twins split their time between the underworld and Mount Olympus. In an aboriginal tale, the same constellation represents the twin lizards who created the plants and animals and saved women from evil spirits. Another example of this strong bond shared between twins is the Ibeji twins from African mythology. Ibeji twins are viewed as one soul shared between two bodies. If one of the twins dies, the parents then create a doll that portrays the body of the deceased child, so the soul of the deceased can remain intact for the living twin. Without the creation of the doll, the living twin is almost destined for death because it is believed to be missing half of its soul. Twins in mythology are often associated with healing. They are also often gifted with the ability of divination or insight into the future.

In Greek mythology, Leda (/ˈliːdə, ˈleɪ-/; Ancient Greek: Λήδα [lɛ́ːdaː]), also rendered Lede, was an Aetolian princess who became queen consort of Sparta through her marriage to King Tyndareus. Zeus fell in love with Leda, and to avoid his wife Hera's jealousy, seduced her while disguised as a swan. Leda was named as the mother of four famous children in Greek mythology: Helen of Troy, Clytemnestra, and the twins Castor and Pollux. Leda and the Swan was a popular motif in the visual arts, particularly during the Renaissance.

In Greek mythology, there were two women known as Philonoe /fɪˈloʊnoʊˌiː/ (Ancient Greek: Φιλονόη) or Phylonoe (Φυλονόη):

• Philonoe, a Spartan princess as the daughter of King Tyndareus and Leda, daughter of King Thestius of Pleuron. She was the sister of Castor and Pollux, Helen, Clytemnestra, Timandra and Phoebe. Artemis made her immortal.
• Philonoe, daughter of Iobates and first wife of Bellerophon by whom, she became the mother of Isander (Peisander), Hippolochus and Laodamia (Deidamia or Hippodamia). Philonoe was the sister of Stheneboea who loved Bellerophon more than her current husband, King Proetus of Argos. She was promised to Bellerophon after he vanquished the Chimera, the Amazons, and more tasks. Bellerophon was given half the kingdom as well as Philonoe's hand in marriage. She was also known under several other names: Alkimedousa or Cassandra, Anticleia, or Pasandra.

The gens Quinctia, sometimes written Quintia, was a patrician family at ancient Rome. Throughout the history of the Republic, its members often held the highest offices of the state, and it produced some men of importance even during the imperial period. For the first forty years after the expulsion of the kings the Quinctii are not mentioned, and the first of the gens who obtained the consulship was Titus Quinctius Capitolinus Barbatus in 471 BC; but from that year their name constantly appears in the Fasti consulares.

As with other patrician families, in later times there were also plebeian Quinctii. Some of these may have been the descendants of freedmen of the gens, or of patrician Quinctii who had voluntarily gone over to the plebs. There may also have been unrelated persons who happened to share the same nomen.

The Battle of Lake Regillus was a legendary Roman victory over the Latin League shortly after the establishment of the Roman Republic and as part of a wider Latin War. The Latins were led by an elderly Lucius Tarquinius Superbus, the seventh and last King of Rome, who had been expelled in 509 BC, and his son-in-law, Octavius Mamilius, the dictator of Tusculum. The battle marked the final attempt of the Tarquins to reclaim their throne. According to legend, Castor and Pollux fought on the side of the Romans.

Aulus Postumius Albus Regillensis was an ancient Roman who, according to Livy, was Roman dictator in 498 or 496 BC, when he conquered the Latins in the great Battle of Lake Regillus and subsequently celebrated a triumph. Many of the coins of the Postumii Albi commemorate this victory of their ancestor, as in the one pictured. Roman folklore related that Castor and Pollux were seen fighting in this battle on the side of the Romans, whence the dictator afterwards promised a temple to Castor and Pollux in the Roman Forum.

He was consul in 496 BC, in which year some of the annals, according to Livy, placed the battle of Lake Regillus; and it is to this year that Dionysius assigns it. The name "Regillensis" is usually supposed to have been derived from this battle; but Niebuhr thinks that it was taken from a place of residence, just as the Claudii bore the same name, and that the later annalists only spoke of Postumius as commander in consequence of the name. Livy states expressly that Scipio Africanus was the first Roman who obtained a surname from his conquests. In 495 BC, Postumius was chosen at short notice by the Romans to lead the cavalry to victory against a Sabine invading force. In 493 BC Postumius was one of the ten envoys sent by the senate to treat with the plebeian leaders during the first secessio plebis.
