If i could travel in time

If i could travel in time i would go to many places but specially to the ancient world. First i would go to the ancient greek civilization to talk with the gratest thinkers of that time, to exchange ideas and learn about them things, like why do they develope that kind of thinking etc. It would also be a good idea to saw how the democracy develope and how do they use it, and talk to the senators. Once i do that i will go to many greek cities and learn about their ways of life, their art, architecture and specially they food which is very known arround the world. I will go to learn about their wapons and strategies in the battle field, how do they organise to attack etc. I would aslo be very interested in going to the library of Alejandria and read all what i want to get to know more about ancient world and I would definitly protect the library from the great fire that consumed it because if it wouldn't be burn we would probably know more about many things and maybe we will be more advance in technologies for example in medicine.
Another thing a would like to do is to learn about their mythology, to learn all the stories about the gods, how the earth and life were created and all their theories about life and their gods.

Then i would go to the Persian empire because it was amasing what they achieved, i have always been interested in the persain civilization because of their traditions, ways of living, and their magnificent architecture, i would go to know each palace with their magestic architecture, colosal size, their beautiful fountains and interiors with it's great design formed by many geometrical forms and color i would also like to learn their language, and their traditions. I would also like to learn about their armies and weapons, how do they create and design them what use they have how to use them. Also to taste their famous condimented food and learn how to do it and their great cities like Babilon, and people from all over the ancient world living together. I also like to admire their handcraft and sculptures.One thing i would change is the war between the greeks and the Persian Empire because when Alexander the great defated the persian he burned their capital Persepolis an leave little evidence of their existence, that's another reason i would like to visit the Persian Empire.
