Medieval Art used 'Mind Trick' instead of 'Perspective'. Then this happened!

Ubiquitous use of colour implies use of a phenomenon called chromosteriosis which makes it easy to judge distance. ALSO, Did changing solar intensity affect the transition from chromosteriospic art to perspective art in Italy?! We believe the drop in intensity of sunlight undermined the effect of making red objects appear at the forefront and blue objects in the background, hence the need to shift to perspective in human art with shift in solar output. =)

How the heck did we survive being as blind as we are? I wear contacts and I find everything to be too bright. Sunlight reflecting off anything white, car lights at night. Every one I know has some corrected vision. Did our eyes evolve under a weaker sun? A more cloudy sky? Thanks for the vid!

Love how you apply your creative mind to this kind of stuff. You always have a fun, fresh take on historical topics like this.

Look at distant mountains, they appear bluish. Air scatters blue light, distant objects have more air in between and hence have a bluish tinge. Registering blue as distant is an likely an evolutionary trait exploiting this effect.

Brunelleschi 's perspective system of mathematically measurable single point was around 1415. Northern artists came across a similar system by trial an error. Earlier artists had used an imprecise perspective system.

The explanation of the invention of Perspective is totally unfounded. Not even the most naively fatalist Stoic would imagine that specific secondary effects, distant and culturally overdetermined, such as the invention of the Perspective or the collective paranoia of Witchcraft, derived from a very general condition such as the lowering of the climatic temperature. With regard to the Perspective, which Lorenzo Ghiberti and Leon Battista Alberti invented by rediscovering the classical style of Antiquity, it should then be noted that in the Middle Ages the paintings could not be viewed in the light of the open space (en plein air), but only in the churches, which were places where light always played with large spaces of penumbra. Therefore, I do not understand how the alleged decrease in brightness (presumed, since Italy is not close to the latitudes of Scandinavia) could in itself determine the transition to Perspective representation.

0:59 about sun light spectrum... holy sh*t, mind blown!

[jamesparker]

So i guess the dark ages were really about sun light and not.about our so called unenlightened ancestors.haaa get it .

As an artist it's hard for me to understand no perspective theory, especially when considering planning of detailed buildings and churches. I see that sketch of perspective without color and wonder how the hell did they even plan buildings without it. To generate a 3d structure from a 2d plan with no linear perspective. How didn't he engineer plan that in his head, without some form of perspective?

Fun fact: The first picture in the video could be seen hanging on the wall of the Gryffindor dorm room in „Harry Potter and the philosopher‘s stone“.

i'm still reaching for the 3d glasses everytime i see some medieval art. fascinating.

That was fun - thanks for pointing out how color can evoke depth. Leonardo DaVinci wrote an explanation of "atmospheric perspective, " how far away objects take on a blue appearance because of the haze of air between the viewer and the objects, and the farther away they are the bluer they look. He used that principle in painting his landscapes. It would be so cool if some earlier artist had left a written explanation of their own reasoning for why blue backgrounds look far away.

I like that the subjects are varied. Whilst Ancient Egypt is obviously key in our understanding of our true last, it's only part of the story. The DNA videos were also highly engaging. Good work Charles.

[AncientMysteriesAndInnovations]

I always watch your videos twice and make sure to thumbs up REAL research and knowledge like the good Doctor

Brilliant publication Dr all the very best to you...

This made me think of Homer's "A wine dark sea". I know, different time period. But still.

[jeffreyarnold]

i'd like to ad a few bits to this hypothesis if i may. some from personal experience. before my eyes began the macular degeneration effect, i had 20/10 vision. i also could see color, and had depth perception in the dark. normally the human eye is limited in that. however if there was any blue light source everything became somewhat "milky." another consideration in art, where the divine, or a nobility was the subject, blue was frequently used. ground lapis was a luxury tint, so reserved for this.

[purplesky]

Is this kind of how old school blue/red 3-D glasses worked as well?

[seapea]

Mind-blowing. Perhaps this effect would have been enhanced with the use of natural light, when used on stained-glass windows for non-linier perspective art from this period.

[JEDEYEZBIZNIZ]

You have 2 keen eyes but use 3 very well Charles!

Something to do with wave length for those can see red and blue color.

Red / violet are located on the extreme visible spectrum, next is red / blue.

Red-red or blue-blue objects placed unequal distance from us cause our eyes to refocus between them. Our brain was trained for depth perception by refocus.

Red has longer wave length than blue. Red / blue spots on an artwork straight at us also cause our eyes to refocus between red-blue spots. With refocusing between red:blue spots, our brain alluded that red is closer than blue. Regardless the artwork is 1m or 1km to us.
