Theseus is one of the great heroes of Greek mythology. His exploits demonstrate his intelligence, sense of justice, and great physical skill. Theseus is thought to be the one who united Attica (region of Greece where Athens is), showing him to be a great king and politician. Civilization conquering barbarism and unnaturalness was an important theme for the city of Athens, so of course her greatest hero would bring justice, and order to the world. Theseus is truly the perfect hero for Athens, the center of ancient Greek culture and academics.
We give and get instructions all of the time, whether it is a tutorial on a website, a recipe for dinner, or directions to the post office. We go through various processes too, as do many natural phenomena. Life cycles, routines, photosynthesis, digestion - processes are everywhere! Instructions and processes are so much more easily understood when accompanied by visuals. When we storyboard a process or create a sequential diagram, we can focus on discrete steps, cause and effect, and sequence.
