Atlas comes from Greek mythology, where the Titan of that name was condemned to hold up the sky, and the word itself is thought by some scholars to relate to endurance or suffering, though its deeper roots are debated. As a given name it points toward capacity -- the ability to carry weight without buckling under it.
Saturn should be asked for limitation of movements, hiding of secrets, impoverishment of countries, decrease of intentions, temptation of souls and water stagnation. - Picatrix (Andalusia, ~1000.AD)
