You can unlock this as early as DNA Sequence 2. Whenever you scan a glyph, you activate a puzzle that you need to decode which is a segment of a vision called the ‘Pieces of Eden’.
Following “Tip of the Iceberg”, you need to solve the puzzle presented to you which involves selecting five pieces of artwork that have similarities with one another. There is no time limit. When you pick out the correct “mythic scenes”, you will unlock the first file of the vision and this achievement.
The first glyph available is at the top of La Rosa Colta, the building where you agree to meet Annetta at (to start the memory ‘Fitting In’ in DNA Sequence 2).
Refer to “Vitruvian Man” for a video showing the locations and puzzle solutions for all 20 glyphs.
