The image shows the two crosses: Cygnus to the left and Crux to the right. Both extend across the galactic equator. The following data illustrates similarities and differences between the crosses of both hemispheres. Southern Cross Cygnus Icon Image Becrux 1.25 Coal Sack (dark nebula) Jewel Box (NGC 4755) Open cluster, A-shaped. Southern Cross Name Stars of apparent magnitude < 3 4 Visible in the range of latitudes... 20 to –90 degrees 68 square degrees Area Apparent magnitude Nebula Cluster Deneb 1.25 NGC 7000 (bright nebula) M29 Open cluster; shaped as a spoon. Northern Cross 4 90 to –40 degrees 804 square degrees IV. The Southern Cross and the mythology of the original cultures of the Andes.

Then the coihue (a native tree) buried itself in the mud as a ship running aground, and when the wind dried the ground the Puma (a native feline), the Chilla (a native mouse) and the children jumped from the log and looked for a hidden valley to live. The first thing they did, even before building another ruca or looking for a cave to inhabit, was to name their adoptive children. Magical names that would protect them forever. The son was named Manque, the condor that soars in the sky looking after the Earth. The daughter was named Melipal, like the Southern Cross.” There are other known connections to the Southern Cross, which we mention now: • The ancient indigenous farmers of the Andes observed the occurrence of astronomical phenomena in order to determine the epoch of their agricultural or
