Vermeer in the context of "Baroque painting"

Lapis lazuli (UK: /ˌlæpɪs ˈlæz(j)ʊli, ˈlæʒʊ-, -ˌli/; US: /ˈlæz(j)əli, ˈlæʒə-, -ˌliˌ læˈzuːli/) is a deep-blue metamorphic rock used as a semi-precious stone that has been prized since antiquity for its intense color. Its name originates from the Persian word for the gem, lāžward, and serves as the root for the word for "blue" in several languages, including Spanish and Portuguese azul and English azure. Lapis lazuli is a rock composed primarily of the minerals lazurite, pyrite, diopside, and calcite. As early as the 7th millennium BC, lapis lazuli was mined in the Sar-i Sang mines, in Shortugai, and in other mines in Badakhshan province in modern northeast Afghanistan. Lapis lazuli artifacts, dated to 7570 BC, have been found at Bhirrana, which is the oldest site of Indus Valley Civilisation. Lapis was highly valued by the Indus Valley Civilisation (3300–1900 BC). Lapis beads have been found at Neolithic burials in Mehrgarh, the Caucasus, and as far away as Mauritania. It was used in the funeral mask of Tutankhamun (1341–1323 BC).

By the end of the Middle Ages, Europe began importing lapis lazuli to grind it into powder and make ultramarine pigment. Ultramarine was used by some of the most important artists of the Renaissance and Baroque, including Masaccio, Perugino, Titian and Vermeer; it was often reserved for the clothing of the central figures of their paintings, especially the Virgin Mary. Ultramarine has also been found in dental tartar of medieval nuns and scribes, perhaps as a result of licking their painting brushes while producing medieval texts and manuscripts.

The Dutch, or Netherlanders (Dutch: Nederlanders), are an ethnic group native to the Netherlands. They share a common ancestry and culture and speak the Dutch language. Dutch people and their descendants are found in migrant communities worldwide, notably in Argentina, Aruba, Australia, Brazil, Canada, Caribbean Netherlands, Curaçao, Germany, Guyana, Indonesia, New Zealand, Sint Maarten, South Africa, Suriname, and the United States. The Low Countries were situated around the border of France and the Holy Roman Empire, forming a part of their respective peripheries and the various territories of which they consisted had become virtually autonomous by the 13th century. Under the Habsburgs, the Netherlands were organised into a single administrative unit, and in the 16th and 17th centuries the Northern Netherlands gained independence from Spain as the Dutch Republic. The high degree of urbanisation characteristic of Dutch society was attained at a relatively early date. During the Republic the first series of large-scale Dutch migrations outside of Europe took place.

The traditional arts and culture of the Dutch encompasses various forms of traditional music, dances, architectural styles and clothing, some of which are globally recognisable. Internationally, Dutch painters such as Rembrandt, Vermeer and Van Gogh are held in high regard. The predominant religion among the Dutch is Christianity, encompassing both Latin Catholicism and Calvinist Protestantism. However, in contemporary times, the majority no longer adhere to a particular Christian denomination. Significant percentages of the Dutch are adherents of humanism, agnosticism, atheism or individual spirituality (including ietsism).

The Caravaggisti (or the "Caravagesques"; singular: "Caravaggista") were stylistic followers of the late 16th-century Italian Baroque painter Caravaggio. His influence on the new Baroque style that eventually emerged from Mannerism was profound. Caravaggio never established a workshop as most other painters did, and thus had no school to spread his techniques. Nor did he ever set out his underlying philosophical approach to art, the psychological realism which can only be deduced from his surviving work. But it can be seen directly or indirectly in the work of Rubens, Jusepe de Ribera, Bernini, and Rembrandt. Famous while he lived, Caravaggio himself was forgotten almost immediately after his death. Many of his paintings were re-ascribed to his followers, such as The Taking of Christ, which was attributed to the Dutch painter Gerrit van Honthorst until 1990.

Only in the 20th century was Caravaggio's importance to the development of Western art rediscovered. In the 1920s Roberto Longhi once more placed him in the European tradition: "Ribera, Vermeer, La Tour and Rembrandt could never have existed without him. And the art of Delacroix, Courbet and Manet would have been utterly different". The influential Bernard Berenson stated: "With the exception of Michelangelo, no other Italian painter exercised so great an influence."
