notes:
|
Scoresby describes the optical effects as occurring in bright evening sunlight. In figure 1, "Hummocks of ice assumed the forms of castles, obelisks, and spires ... masses of rocks and summits of mountains were reared to an enormous elevation, distorted into singular shapes ... and freely suspended in the air." In figure 2, images of distant ships were seen suspended inverted in the air, and their shapes were distorted.William Scoresby, born in Yorkshire of a father who made his fortune in whaling, became an Arctic explorer and, later, a clergyman. His observations of natural phenomena contributed to the understanding of Arctic conditions. He also mapped and charted the east coast of Greenland on his voyage there in 1823.The engraver is probably William Home Lizars, Scottish painter and engraver (1788-1859).
