Title: Io (mythology)
Content:  Io was, in Greek mythology, one of the mortal lovers of Zeus. An Argive princess, she was an ancestor of many kings and heroes, such as Perseus, Cadmus, Heracles, Minos, Lynceus, Cepheus, and Danaus. The astronomer Simon Marius named a moon of Jupiter after Io in 1614. Because her brother was Phoroneus, Io is also known as Phoronis (an adjective form of Phoroneus: "Phoronean"). She was sometimes compared to the goddess Isis, whereas her Egyptian husband Telegonus was "Osiris".
Title: Io (mythology)
Content:  In most versions of the legend, Io was the daughter of Inachus, though various other purported genealogies are also known. If her father was Inachus, then her mother would presumably have been Inachus' wife (and sister), the Oceanid nymph Melia, daughter of Oceanus. The 2nd century AD geographer Pausanias also suggests that she is the daughter of Inachus and retells the story of Zeus falling in love with Io, the legendary wrath of Hera, and the metamorphosis by which Io becomes a beautiful white heifer. At another instant several generations later, Pausanias recounts another Io, descendant of Phoroneus, daughter of Iasus, who himself was the son of Argus and Ismene, the daughter of Asopus, or of Triopas and Sosis; Io's mother in the latter case was Leucane. Io's father was called Peiren in the Catalogue of Women, and by Acusilaus, possibly a son of the elder Argus, also known as Peiras, Peiranthus or Peirasus. Io may therefore be identical to Callithyia, daughter of Peiranthus, as is suggested by Hesychius of Alexandria.

Later in the story, Isis (Io) changes Iphis' sex when she is supposed to marry her fiancée, Ianthe.
Title: Io (princely title)
Content:  The ultimate origin of Io is with the Biblical Yohanan (יוֹחָנָן), a reference to the divine right, and, in the baptismal name "John", an implicit expression of thanks for the child's birth; the abbreviation is performed as with other nomina sacra, but appears as Ioan in Orthodox Church ectenia. The Slavonic Ιω very often features a tilde over the second letter, which is indicative of a silent "n". Io is therefore described by scholar Emil Vârtosu as "both name and title". Its connection to the name "John", and its vocalization as Ioan, are explicitly mentioned by Paul of Aleppo, who visited Wallachia in the 1650s. However, he provides 
Title: Io (mythology)
Content:  Io was a priestess of the Goddess Hera in Argos, whose cult her father Inachus was supposed to have introduced to Argos. Zeus noticed Io, a mortal woman, and lusted after her. In the version of the myth told in Prometheus Bound she initially rejected Zeus' advances, until her father threw her out of his house on the advice of oracles. According to some stories, Zeus then turned Io into a heifer (a cow) in order to hide her from his wife; others maintain that Hera herself transformed Io. In the version of the story in which Zeus transformed Io, the deception failed, and Hera begged Zeus to give her the heifer as a present, which, having no reason to

Prometheus comforted Io with the information that she would be restored to human form and become the ancestress of the greatest of all heroes, Heracles (Hercules). Io escaped across the Ionian Sea to Egypt, where she was restored to human form by Zeus. There, she gave birth to Zeus's son Epaphus, and a daughter as well, Keroessa. She later married Egyptian king Telegonus. Their grandson, Danaus, eventually returned to Greece with his fifty daughters (the Danaids), as recalled in Aeschylus' play The Suppliants. The myth of Io must have been well known to Homer, who often calls Hermes Argeiphontes, which is often translated as

The customary English pronunciation of the name is, though sometimes people attempt a more 'authentic' pronunciation,. The name has two competing stems in Latin: Īō and (rarely) Īōn. The latter is the basis of the English adjectival form, Ionian. Features on Io are named after characters and places from the Io myth, as well as deities of fire, volcanoes, the Sun, and thunder from various myths, and characters and places from Dante's Inferno: names appropriate to the volcanic nature of the surface.

As they celebrate their change of fortune, Ion takes her aside to ask if perhaps she conceived him with a mortal father and made up the story about Apollo. After all, Apollo said that Xuthus was his father. Convinced that only Apollo can tell him for certain who his father is, Ion starts toward the sanctuary to confront the god, but he is stopped by the appearance of the goddess Athena on the roof of the temple (an instance of deus ex machina). Athena explains that Apollo thought

Content:  explanation for why this particular name was favored. Historian Radu G. Păun describes it specifically as a "theophoric name", which "served to highlight that princely power derives directly from God and not from an intermediary agency". Theologian Ion Croitoru argues that Io placed Wallachian and Moldavian Princes under the patronage of John the Evangelist, and that it doubles as a reference to their status as defenders of the Orthodox faith. The intermediate origin of Io is the Second Bulgarian Empire (1185–1396), located just south of early medieval territories which became Wallachia and Moldavia. As noted by historian A. D. Xenopol, it honors Ivan I Asen, in line
