The mountain 
Koryaksky 3,456 m (11,339 ft) or Koryakskaya Sopka Коря́кская со́пка)  is an active volcano on the Kamchatka Peninsula in the Russian Far East, the asian part of russia. It lies within sight of Kamchatka Krai's administrative center, Petropavlovsk-Kamchatsky. Together with neighbouring Avachinsky, it has been designated a Decade Volcano, worthy of particular study in light of its history of explosive eruptions and proximity to populated areas.
Koryaksky lies on the Pacific Ring of Fire, at a point where the Pacific Plate is sliding underneath the Eurasian Plate at about 80 mm/year. A wedge of mantle material lying between the subducting Pacific Plate and the overlying Eurasian Plate is the source of dynamic volcanism over the whole Kamchatka Peninsula. The volcano has probably been active for tens of thousands of years. Geological records indicate that there have been three major eruptions in the last 10,000 years, at 5500 BC, 1950 BC and 1550 BC. These three eruptions seem to have been mainly effusive, generating extensive lava flows. Koryaksky erupted for the first time in recorded history in 1890. The eruption was characterised by lava emissions from fissures that opened up on the volcano's southwestern flank, and by phreatic explosions. It was thought to have erupted again five years later, but it was later shown that no eruption had occurred; what was thought to be an eruption column was simply steam generated by strong fumarolic activity. Another brief, moderately explosive eruption occurred in 1926, after which the volcano lay dormant until 1956. The 1956 eruption was more explosive than the previous known eruptions, with VEI=3, and generated pyroclastic flows and lahars. The eruption continued until June 1957. On December 29, 2008, Koryaksky erupted with a 6,000 m (20,000 ft) plume of ash, the first major eruption in 3,500 years.
In light of its proximity to Petropavlovsk-Kamchatsky, Koryaksky was designated a Decade Volcano in 1996 as part of the United Nations' International Decade for Natural Disaster Reduction, together with the nearby Avachinsky volcano.

The painter 
Friedrich Georg Weitsch was a German painter and etcher. Weitsch began his artistic training with his father, "Pascha" Johann Friedrich Weitsch (1723–1803). He attended the Kunstakademie Düsseldorf. After traveling to Amsterdam and Italy between 1784 and 1787, he returned home and became court painter to Charles William Ferdinand, Duke of Brunswick.  In 1794 he became a member of the Berlin Academy of Art and became its director in 1798 (succeeding Bernhard Rode).  His work included landscapes, history and religious painting, and portraits of royal and civil authorities—the latter showing the influence of Anton Graff.  Some are held at the Herzog Anton Ulrich Museum, the Städtisches Museum, and the Braunschweigisches Landesmuseum, all in Braunschweig.  He painted the very famous painting of the Chimborazo  featuring the portrait of Alexander von Humboldt with  landscape he imagined as well as the portrait of Aimé Bonpland and Carlos Montufarin Ecuador, he never saw.

EL CHIMBORAZO PAINTED BY FRIEDRICH WEITSCH

The mountain

Chimborazo  (6,263 m -20,548 ft) is a currently inactive stratovolcano in the Cordillera Occidental range of the Andes ans the highest mountain in Ecuador and the Andes north of Peru ; it is higher than any more northerly summit in the Americas. Chimborazo is not the highest mountain by elevation above sea level, but its location along the equatorial bulge makes its summit the farthest point on the Earth's surface from the Earth's center.

Chimborazo is at the main end of the Ecuadorian Volcanic Arc, north west of the town of Riobamba. Chimborazo is in la Avenida de los Volcanes (the Avenue of Volcanoes) west of the Sanancajas mountain chain. Carihuairazo, Tungurahua, Tulabug, and El Altar are all mountains that neighbor Chimborazo.  The closest mountain peak, Carihuairazo, is 5.8 mi (9.3 km) from Chimborazo. There are many microclimates near Chimborazo, varying from desert in the Arenal to the humid mountains in the Abraspungo valley. Its last known eruption is believed to have occurred around A.D. 550. 

Until the beginning of the19th century, it was thought that Chimborazo was the highest mountain on Earth (measured from sea level), and such reputation led to many attempts on its summit during the 17th and 18th centuries.

In 1746, the volcano was explored by French academicians from the  French Geodesic Mission. Their mission was to determine the sphericity of the Earth. Their work along with another team in Lapland established that the Earth was an oblate spheroid rather than a true sphere. They did not reach the summit of Chimborazo.

In 1802, during his expedition to South America, Baron Alexander von Humboldt (on left in the painting above)  accompanied by Aimé Bonpland (on right in the painting above) and the Ecuadorian Carlos Montufar (on left with Humboldt  in the painting above), tried to reach the summit. From his description of the mountain, it seems that before he and his companions had to return suffering from altitude sickness they reached a point at 5,875 m, higher than previously attained by any European in recorded history. (Incas had reached much higher altitudes previously). In 1831, Jean-Baptiste Boussingault and Colonel Hall reached a new "highest point", estimated to be 6,006 m.
