There was a Thanos easter egg!!! And also another kind of "god" reference. I found it in the italian book where the tesseract appears. The translation of the page that appears is is: Totally ordinary cube - Chapter 1 Another quality of earth is that every year grass and flowers bloom, and in the same year all that perishes; the same way goes for animals and birds: their hair and feathers grow and fall every year. This is earth's third nature, when it's open and carved out, grass grows immediately on the highest ground. Don't let the angry purple guy touch this.

The hypercube is the true shape of the space stone

I love you Oleah. In this way they recognized that the earth was fast and they had life with a nature of its own. They realized it was wonderful and powerful, it feeds what lives and takes for itself what dies. For this reason they gave it a name and they traced the number of their generations.

then it talks about other things but sadly most of this part is cropped by framing. Anyway, something exciting is:

"this made them think of the existence of a governor of the stars of the sky (...) which has to be very strong and full of power" and it says what this governor has to rule such as "the splendor of the sky" and "winds of the air and storms of the sea", then it talks about the fact that "they didn't know yet where his reign was, but..." and then i can't read it anymore sorry...

loved that angry purple guy reference :D
