In Christian theology, justification is the event or process by which sinners are made or declared to be righteous in the sight of God.

In the 21st century, there is now substantial agreement on justification by most Christian communions. The collective bodies of most of the largest Christian denominations, including Catholic, Lutheran, Reformed, Anglican and Methodist, have affirmed a 1999 Lutheran–Catholic Joint Declaration on the Doctrine of Justification that details this consensus, noting different distinctive emphases that individual communions consider essential to state.

In religion and folklore, hell is a location or state in the afterlife in which souls are subjected to punishment after death. Religions with a linear divine history sometimes depict hells as eternal, such as in some versions of Christianity and Islam, whereas religions with reincarnation usually depict a hell as an intermediary period between incarnations, as is the case in the Indian religions. Religions typically locate hell in another dimension or under Earth's surface. Other afterlife destinations include heaven, paradise, purgatory, limbo, and the underworld.

Other religions, which do not conceive of the afterlife as a place of punishment or reward, merely describe an abode of the dead, the grave, a neutral place that is located under the surface of Earth (for example, see Kur, Hades, and Sheol). Such places are sometimes equated with the English word hell, though a more correct translation would be "underworld" or "world of the dead". The ancient Mesopotamian, Greek, Roman, and Finnic religions include entrances to the underworld from the land of the living.

A tondo (pl.: tondi or tondos) is a Renaissance term for a circular work of art, either a painting or a sculpture. The word derives from the Italian rotondo, "round". The term is usually not used in English for small round paintings, but only those over about 60 cm (two feet) in diameter, thus excluding many round portrait miniatures – for sculpture the threshold is rather lower.

A circular or oval relief sculpture is also called a roundel. The infrequently-encountered synonym rondo usually refers to the musical form.

The Holy Lance, also known as the Spear of Longinus (named after Saint Longinus), the Spear of Destiny, or the Holy Spear, is alleged to be the lance that pierced the side of Jesus as he hung on the cross during his crucifixion. As with other instruments of the Passion, the lance is only briefly mentioned in the Christian Bible, but later became the subject of extrabiblical traditions in the medieval church. Relics purported to be the lance began to appear as early as the 6th century, originally in Jerusalem. By the Late Middle Ages, relics identified as the spearhead of the Holy Lance (or fragments thereof) had been described throughout Europe. Several of these artifacts are still preserved to this day.

Holy Lance relics have typically been used for religious ceremonies, but at times some of them have been considered to be guarantees of victory in battle. For example, Henry the Fowler's lance was credited for winning the Battle of Riade, and the Crusaders believed their discovery of a Holy Lance brought them a favorable end to the Siege of Antioch.

In Christian theology, the Harrowing of Hell (Latin: Descensus Christi ad Inferos; Greek: Ἡ εἰς ᾍδου κάθοδος τοῦ Χριστοῦ – "the descent of Christ into Hell" or "Hades") is the period of time between the Crucifixion of Jesus and his resurrection. In triumphant descent, Christ brought salvation to the souls held captive there since the beginning of the world.

Christ's descent into the world of the dead is referred to in the Apostles' Creed and the Athanasian Creed (Quicumque vult), which state that he "descended into the underworld" (descendit ad inferos), although neither mention that he liberated the dead. His descent to the underworld is alluded to in the New Testament in 1 Peter 4:6, which states that the "good tidings were proclaimed to the dead". The Catechism of the Catholic Church notes Ephesians 4:9, which states that "[Christ] descended into the lower parts of the earth", as also supporting this interpretation. These passages in the New Testament have given rise to differing interpretations. The Harrowing of Hell is commemorated in the liturgical calendar on Holy Saturday.

In religion and folklore, paradise is a place of everlasting happiness, delight, and bliss. Paradisiacal notions are often laden with pastoral imagery, and may be cosmogonical, eschatological, or both, often contrasted with the miseries of human civilization: in paradise there is only peace, prosperity, and happiness. Paradise is a place of contentment, a land of luxury and fulfillment containing ever-lasting bliss and delight. Paradise is often described as a "higher place", the holiest place, in contrast to this world, or underworlds such as hell.

In eschatological contexts, paradise is imagined as an abode of the virtuous dead. In Judaism, Christianity, and Islam, heaven is a paradisiacal belief. In Hinduism and Buddhism, paradise and heaven are synonymous, with higher levels available to beings who have achieved special attainments of virtue and meditation. In old Egyptian beliefs, the underworld is Aaru, the reed-fields of ideal hunting and fishing grounds where the dead lived after judgment. For the Celts, it was the Fortunate Isle of Mag Mell. For the classical Greeks, the Elysian fields was a paradisiacal land of plenty where adherents hoped the heroic and righteous dead would spend eternity. In the Zoroastrian Avesta, the "Best Existence" and the "House of Song" are places of the righteous dead. On the other hand, in cosmogonical contexts 'paradise' describes the world before it was tainted by evil.

Jean (or Jehan) Fouquet (French: [fuke]; c. 1420 – 1481) was a French painter and miniaturist. A master of panel painting and manuscript illumination, and the apparent inventor of the portrait miniature, he is considered one of the most important painters from the period between the late Gothic and early Renaissance. He was the first French artist to travel to Italy and experience first-hand the early Italian Renaissance.

Little is known of Fouquet's early life and education. Though long assumed to have been an apprentice of the so-called Bedford Master of Paris it is now suggested that he may have studied under the Jouvenal Master in Nantes, whose works were formerly assumed to be early works by Fouquet. Sometime between 1445 and 1447 he travelled to Italy, where he came under the influence of Roman Quattrocento artists such as Fra Angelico and Filarete. During the 1450s he began working at the French court, where he counted kings Charles VII and his successor Louis XI among his many patrons.

San Marco is a Catholic religious complex in Florence, Italy. It comprises a church and a convent. The convent, which is now the Museo Nazionale di San Marco, has three claims to fame. During the 15th century it was home to two famous Dominicans, the painter Fra Angelico and the preacher Girolamo Savonarola. The church houses the relics of St Antoninus of Florence and the tomb of Pico Della Mirandola, a Renaissance philosopher known as the "Father of Humanism."
