Engraving from "Selenografia sive Lunae Descriptio" by Johannes Hevelius, 1647
From the many things that I've learned on this weekend's astronomy class- from equinoxes and the earth's orbit to parsecs and how to determine the latitude based on the North star, I know the ones that will last longer is the fact that I need to go to the southern hemisphere again since I've failed to notice Magellan's clouds before, the very poetic and intriguing thought that one is looking at the past when one looks at the sky and how Camões' Lusiads is filled with pieces of geocentric astronomy theory.

Por este largo mar enfim me alongo Do conhecido pólo de Calisto, Tendo o término ardente já passado, Onde o meio do mundo é limitado. Já descoberto tínhamos diante, Assim passando aquelas regiões | From this open sea I looked my last At the constellations of the North. For we had by now crossed the burning line Which marks division in the earth's design. Our sailors had discovered long since By now we had left behind both tropics |
Os Lusíadas, Canto V
