John William Waterhouse in the context of "Medievalism"

An oracle is a person or thing considered to provide insight, wise counsel or prophetic predictions, most notably including precognition of the future, inspired by deities. If done through occultic means, it is a form of divination.

In Greek mythology, the suitors of Penelope (also known in Latin as the Proci) are one of the main subjects of Homer's Odyssey.

Witchcraft is the use of magic by a person called a witch. Traditionally, "witchcraft" means the use of magic to inflict supernatural harm or misfortune on others, and this remains the most common and widespread meaning. Though the idea of witchcraft is largely imaginary, it has nevertheless served in many cultures as a way to explain the presence of evil. The belief in witches has been found throughout history in a great number of societies worldwide. Most of these societies have used protective magic or counter-magic against witchcraft, and have shunned, banished, imprisoned, physically punished or killed alleged witches. Anthropologists use the term "witchcraft" for similar beliefs about harmful occult practices in different cultures, and these societies often use the term when speaking in English.

Belief in witchcraft as malevolent magic is attested from ancient Mesopotamia, and in Europe, belief in witches traces back to classical antiquity. In medieval and early modern Europe, accused witches were usually women who were believed to have secretly used black magic (maleficium) against their own community. Usually, accusations of witchcraft were made by neighbors of accused witches, and followed from social tensions. Witches were sometimes said to have communed with demons or with the Devil, though such accusations were mainly made against perceived opponents of the Church. It was thought witchcraft could be thwarted by white magic, provided by 'cunning folk' or 'wise people'. Suspected witches were often prosecuted and punished, if found guilty or simply believed to be guilty. European witch-hunts and witch trials in the early modern period led to tens of thousands of executions. While magical healers and midwives were sometimes accused of witchcraft, they made up a minority of those accused. European belief in witchcraft gradually dwindled during and after the Age of Enlightenment.

Consulting the Oracle is an oil on canvas painting by John William Waterhouse. Waterhouse painted it in 1884; according to Anthony Hobson, "The Illustrated London News described it as one of the principal works of the year". Hobson describes the work as having a "keyhole composition" because a partial ring of women focus upon a single other (the priestess).

Hobson goes on to say that the painting helps "to establish Waterhouse as a classical painter" because of his use of "classical, geometrical structures...the vertical, the horizontal and the circle". When he adds the diagonal, as "in the inclined figure of the priestess" and the out-of-place rug, it is a deliberately added tension.

In Greek mythology, Pandora was the first human woman created by Hephaestus on the instructions of Zeus. As Hesiod related it, each god cooperated by giving her unique gifts. Her other name—inscribed against her figure on a white-ground kylix in the British Museum—is Anesidora (Ancient Greek: Ἀνησιδώρα), "she who sends up gifts" (up implying "from below" within the earth).

The Pandora myth is a kind of theodicy, addressing the question of why there is evil in the world, according to which, Pandora opened a jar (pithos; commonly referred to as "Pandora's box") releasing all the evils of humanity. It has been argued that Hesiod's interpretation of Pandora's story went on to influence both Jewish and Christian theology and so perpetuated her bad reputation into the Renaissance. Later poets, dramatists, painters and sculptors made her their subject.

The Pre-Raphaelite Brotherhood (PRB), later known as the Pre-Raphaelites, was a group of English painters, poets, and art critics, founded in 1848 by William Holman Hunt, John Everett Millais, Dante Gabriel Rossetti, William Michael Rossetti, James Collinson, Frederic George Stephens and Thomas Woolner who formed a seven-member "Brotherhood" partly modelled on the Nazarene movement. The Brotherhood was only ever a loose association and their principles were shared by other artists and poets of the time, including Algernon Charles Swinburne, William Morris, Ford Madox Brown, Arthur Hughes and Marie Spartali Stillman. Later followers of the principles of the Brotherhood included Edward Burne-Jones and John William Waterhouse.

The group sought a return to the abundant detail, intense colours and complex compositions of Quattrocento Italian art. They rejected what they regarded as the mechanistic approach first adopted by Mannerist artists who succeeded Raphael and Michelangelo. The Brotherhood believed the Classical poses and elegant compositions of Raphael in particular had been a corrupting influence on the academic teaching of art, hence the name "Pre-Raphaelite". In particular, the group objected to the influence of Sir Joshua Reynolds, founder of the English Royal Academy of Arts, whom they called "Sir Sloshua". To the Pre-Raphaelites, according to William Michael Rossetti, "sloshy" meant "anything lax or scamped in the process of painting ... and hence ... any thing or person of a commonplace or conventional kind". The group associated their work with John Ruskin, an English critic whose influences were driven by his religious background. Christian themes were abundant.
