Religions and cultural traditions all being created around the same time frame was extremely interesting, to give meaning to the phrase, " the Three Great Religions" as a basic foundation most other religions of the world were born. The word "Zoroastrianism" I had never heard before? In all the years of attending Sunday school, sometimes Friday night temple services, and bar/bat mitzvahs, weddings, of never hearing this word is strange. Probably because it became a part of the Jewish religion around 1000 B.C. had something to do with it? Another word I didn't recognize was "Yahweh" as a powerful and jealous deity. In the Old Testament and the first of the Ten Commandment, the Jewish religion only and absolutely believes in one God. This would make a great topic of conversation the next time I ever see a Rabbi. Also, our textbook said some of the key ideas of the Jewish religion were : morals and the principals of social justice. Move time forward to the future in the Holocaust, tragic, horrible genocide done to the Jews from the Nazis who had no morals and/or any principals of social justice. By the way, yes, I do know people with evidence and witnesses testimony to support the case that there actually was a Holocaust.
Slavery has always caught my eye, with no pun intended, for several reasons. Mainly of course, here we go again, for morals and principals of social justice. Similar to India with their caste-based social structure, Chinese civilization with their dynasties, and other Persian, Greek, and Roman Empires, all inequalities of class and caste were dumped on slaves. I always wondered how human nature got started on those boundaries? Who ever had the right for ownership by a master, to be treated less than human? Slavery catching my attention in the visual sense, why I said no pun intended, is because I am an art major. The divine Greek statues, pillars, Roman structures, Egyptian pyramids, Persian mosaics,  fresco paintings, glorious churches, magnificent buildings, were built by slaves. They were designed by someone else, but the labor was done by slaves.
On the subject of art, relative to the perspective of an art major: Paleolithic and Neolithic art involved around female figures, scenes depicting food gathers and/or hunters, with usually symbol representing a spiritual person, animals, and a leader. As time progresses to empires and civilizations, with writing and symbols to tell a narrative with art scenes, the art becomes more advanced. For example, the early stage drawings of people look like stick figures, then they appear with one sided profiles in Egyptian pictures, as we get to Roman frescoes they are realistic people images!
