In this connection, I noticed that she quoted Alexander von Humboldt. It is not surprising, as she has done considerable scholarly work on Humboldt. Humboldt traveled in Latin America between 1799 and 1804. The results of his immense scientific research there appeared in the multi-volume Kosmos. Upon first seeing the Southern Cross in the night sky as he approached the South American continent, however, he did not think about measuring the sky in order to advance our knowledge of the constellations: a scientific enterprise that would in turn help us in predicting weather patterns. Humboldt's first thought was the lines of a poet:
"Impatient to explore the equatorial regions, I could not raise my eyes to the sky without dreaming of the Southern Cross and remembering a passage from Dante."
Humboldt goes on to quote the relevant passage, in Italian (see Purgatory, canto 1, 22–27).
As Professor Millán writes: "Dante's work made a mark so strong in the mind of Humboldt that lines from his poetry became part of the experience of seeing the night sky and understanding the meaning of the Southern Cross for the human observer gazing upon its brilliant light."
