Gustave Moreau in the context of "Oedipus and the Sphinx"

Christian mythology is the body of myths associated with Christianity. The term encompasses a broad variety of legends and narratives, especially those considered sacred narratives. Mythological themes and elements occur throughout Christian literature, including recurring myths such as ascending a mountain, the axis mundi, myths of combat, descent into the Underworld, accounts of a dying-and-rising god, a flood myth, stories about the founding of a tribe or city, and myths about great heroes (or saints) of the past, paradises, and self-sacrifice.

Various authors have also used it to refer to other mythological and allegorical elements found in the Bible, such as the story of the Leviathan. The term has been applied to myths and legends from the Middle Ages, such as the story of Saint George and the Dragon, the stories of King Arthur and his Knights of the Round Table, and the legends of the Parsival. Multiple commentators have classified John Milton's epic poem Paradise Lost as a work of Christian mythology. The term has also been applied to modern stories revolving around Christian themes and motifs, such as the writings of C. S. Lewis, J. R. R. Tolkien, Madeleine L'Engle, and George MacDonald.

The beheading of John the Baptist, also known as the decollation of Saint John the Baptist or the beheading of the Forerunner, is a biblical event commemorated as a holy day by various Christian churches. According to the New Testament, Herod Antipas, ruler of Galilee under the Roman Empire, had imprisoned John the Baptist because he had publicly reproved Herod for divorcing his first wife and unlawfully taking his sister-in-law (his brother's wife) Herodias as his second wife. He then ordered him to be killed by beheading.

As a non-Biblical source, Jewish historian Josephus also recounts that Herod had John imprisoned and killed due to "the great influence John had over the people", which might persuade John "to raise a rebellion". Josephus also writes that many of the Jews believed that Herod's later military disaster was God's punishment for his treatment of John.

The Song of Songs (Biblical Hebrew: שִׁיר הַשִּׁירִים‎, romanized: Šīr hašŠīrīm), also called the Canticle of Canticles or the Song of Solomon, is a biblical poem, one of the five megillot ("scrolls") in the Ketuvim ('writings'), the last section of the Tanakh. Unlike other books in the Hebrew Bible, it is erotic poetry; lovers express passionate desire, exchange compliments, and invite one another to enjoy. The poem narrates an intense, poetic love story between a woman and her lover through a series of sensual dialogues, dreams, metaphors, and warnings to the “daughters of Jerusalem” not to awaken love before its time.

Modern scholarship tends to hold that the lovers in the Song are unmarried, which accords with its ancient Near East context. The women of Jerusalem form a chorus to the lovers, functioning as an audience whose participation in the lovers' erotic encounters facilitates the participation of the reader.

Symbolist painting was one of the main artistic manifestations of symbolism, a cultural movement that emerged at the end of the 19th century in France and developed in several European countries. The beginning of this current was in poetry, especially thanks to the impact of The Flowers of Evil by Charles Baudelaire (1868), which powerfully influenced a generation of young poets including Paul Verlaine, Stéphane Mallarmé and Arthur Rimbaud. The term "symbolism" was coined by Jean Moréas in a literary manifesto published in Le Figaro in 1886. The aesthetic premises of Symbolism moved from poetry to other arts, especially painting, sculpture, music and theater. The chronology of this style is difficult to establish: the peak is between 1885 and 1905, but already in the 1860s there were works pointing to symbolism, while its culmination can be established at the beginning of the First World War.

In painting, symbolism was a fantastic and dreamlike style that emerged as a reaction to the naturalism of the realist painting and Impressionist trends, whose objectivity and detailed description of reality were opposed by subjectivity and the depiction of the occult and the irrational, as opposed to representation, evocation, or suggestion. Just as in poetry the rhythm of words served to express a transcendent meaning, in painting they sought ways for color and line to express ideas. In this movement, all the arts were related and thus the painting of Redon was often compared to the poetry of Baudelaire or the music of Debussy.

Jupiter et Sémélé (1894–95; English, Jupiter and Semele) is a painting by the French Symbolist artist Gustave Moreau (1826–1898). It depicts a moment from the classical myth of the mortal woman Semele, mother of the god Dionysus, and her lover, Jupiter, the king of the gods. She was treacherously advised by the goddess Juno, Jupiter's wife, to ask him to appear to her in all his divine splendor. He obliged, but, in so doing, brought about her violent death by his divine thunder and lightning. The painting is a representation of "divinized physical love" and the overpowering experience that consumes Semele as the god appears in his supreme beauty which has been called "quite simply the most sumptuous expression imaginable of an orgasm".

Of this work, Moreau himself wrote, "Semele, penetrated by the divine effluence, regenerated and purified by this consecration, dies struck by lightning and with her dies the genius of terrestrial love, the genius with the goat hooves."
