Question: Egbert van Drielst studied the works of the preeminent landscape painter of which age?
Context: Paolo Antonio Alboni (1671 – 5 October 1734) was an Italian painter of the late-Baroque period.  He was born and trained in Bologna, where he became a landscape painter.  After practising for some time in Rome and Naples, he went in 1710 to Vienna, where he remained nearly thirteen years, but being deprived of the use of his right side by a stroke, he returned to Bologna; he subsequently painted with his left hand.  His daughter, Luigia Maria Rosa Alboni, was also a landscape painter.  She died in 1759. Sarah Cole (1805-1857) was an American landscape painter and the sister of prominent American landscape painter Thomas Cole.  Many of Cole’s paintings are similar in subject and visuals to her brother’s.  Very little is known of her life, and few of her works have survived or can be located today.  The surviving works have been displayed in collections and museums over the years. Elias Martin {'1': ", '2': ", '3': ", '4': "} (8 March 1739 – 25 January 1818) was a Swedish genre, history, and landscape painter and engraver from Stockholm.  He is known for his watercolour paintings of Stockholm, and his landscape oil paintings that feature romantic lighting effects. " Nationalencyklopedin" describes him as Sweden's "first great landscape painter". Egbert van der Poel (9 March 1621 in Delft – 19 July 1664 in Rotterdam) was a Dutch Golden Age genre and landscape painter, son of a Delft goldsmith. Charles Wellford Leavitt (1871–1928) was an American landscape architect, urban planner, and civil engineer who designed everything from elaborate gardens on Long Island, New York and New Jersey estates to federal parks in Cuba, hotels in Puerto Rico, plans of towns in Florida, New York and elsewhere.  New York publisher Julius David Stern called Leavitt "a rare combination of engineer, artist, and diplomat", and the multi-faceted career chosen by Leavitt, veering between public and private commissions and embracing everything from hard-edged engineering to sensuous garden design, and calling for negotiations with everyone from wealthy entrepreneurs to county commissioners, called for an individual with singular talents.  Leavitt was one of the preeminent landscape architects of his era and helped found the study of landscape architecture at New York City's Columbia University, where he was one of the first three professors in the University's new four-year program in the discipline. Jacob Isaackszoon van Ruisdael (] ;  1629 – 10 March 1682) was a Dutch painter, draughtsman, and etcher.  He is generally considered the pre-eminent landscape painter of the Dutch Golden Age, a period of great wealth and cultural achievement when Dutch painting became highly popular. Lucas van Uden (18 October 1595 – 4 November 1672) was a leading Flemish landscape painter, draughtsman and engraver, who lived and worked in Antwerp.  He was a leading landscape painter who collaborated with various local figure painters.  His most original works are his drawings. Egbert van Heemskerck, or Egbert Jaspersz van Heemskerk (1634–1704) was a Haarlem Dutch Golden Age painter of genre works who died in London in 1704.  He is often confused with another genre painter also called Egbert van Heemskerck who lived c. 1676 – 1744. Pierre-Antoine Patel (November 22, 1648 – March 17, 1707), also known as Patel the Younger, was a French landscape painter.  He was the son of Pierre Patel, also a renowned landscape painter, who, like many French painters of his generation, was influenced by the landscapes of Italy painted by Claude Lorrain.  The younger Patel distinguished himself from his father by specializing in small, finely finished landscapes in gouache, an opaque watercolor.  The majority of his works depict antique ruins, bathed in sunlight. Egbert van Drielst (Groningen, 12 March 1745 – Amsterdam, 4 June 1818) began his study of the painting in a factory in Groningen which produced mainly lacquered objects.  He soon went to Haarlem, where he became an apprentice in the wallpaper factory of Jan Augustini.  Van Drielst entered the wallpaper studio in Amsterdam where he established friendships with Adriaan de Lelie.  He studied the old masters Salomon van Ruysdael, Jacob van Ruisdael, Jan Wijnants and in particular, Meindert Hobbema, and sought to make use of their techniques in his nature studies.  In 1768 he became a member of the Guild of Saint Luke in Amsterdam.
