Johannes, Jan or Johan Vermeer (Dutch pronunciation: [joˈɦɑnəs jɑn vərˈmɪːr];1632 – December 1675) was a Dutch painter who specialized in domestic interior scenes of middle class life. Vermeer was a moderately successful provincial genre painter in his lifetime. He seems never to have been particularly wealthy, leaving his wife and children in debt at his death, perhaps because he produced relatively few paintings.

Vermeer worked slowly and with great care, using bright colours and sometimes expensive pigments, with a preference for cornflower blue and yellow. He is particularly renowned for his masterly treatment and use of light in his work.

Vermeer painted mostly domestic interior scenes. As Koning points out: "Almost all his paintings are apparently set in two smallish rooms in his house in Delft; they show the same furniture and decorations in various arrangements and they often portray the same people, mostly women".

Recognized during his lifetime in Delft and The Hague, his modest celebrity gave way to obscurity after his death; he was barely mentioned in Arnold Houbraken's major source book on 17th century Dutch painting (Grand Theatre of Dutch Painters and Women Artists), and was thus omitted from subsequent surveys of Dutch art for nearly two centuries. In the 19th century Vermeer was rediscovered by Gustav Friedrich Waagen and Théophile Thoré-Bürger, who published an essay attributing sixty-six pictures to him, although only thirty-four paintings are universally attributed to him today. Since that time Vermeer's reputation has grown, and he is now acknowledged as one of the greatest painters of the Dutch Golden Age.

Juan Gutiérrez de Padilla (c. 1590 – 1664) was a Spanish composer in what is modern Mexico.

He was born in Málaga, Spain but moved to Puebla, Mexico, in 1620 to compose music in the New World. At the time New Spain was a viceroyalty of Spain that included modern day Mexico, Guatemala, the Philippines and other parts of Central America and the Caribbean). Padilla is one of the more important composers represented in the manuscripts at Puebla, Mexico and the Hackenberry collection in Chicago, Illinois. He worked at Puebla de Los Angeles, Mexico, which in Baroque times was a bigger religious center than Mexico City itself. He was appointed maestro de capilla of Puebla Cathedral in 1628.

He is to be distinguished from a younger Juan de Padilla, who was maestro de capilla at Zamora, Spain (1661-1663), and Toledo (1663-1673).

The majority of his vast output (over 700 pieces survive) include sacred motets, often for double choir, in the Renaissance style or stile antico as well as sacred villancicos. It often includes accompaniments for organ or various stringed instruments.
