On June 21, the sun will be directly overhead at the Tropic of Cancer - signaling the LONGEST DAYLIGHT for the Northern Hemisphere. The day of the June Summer Solstice has the longest daylight in the Northern Hemisphere and the shortest in the Southern Hemisphere. It’s Winter Solstice for those in the south and most of Antarctica also do not receive any sunlight during this time.

Iceland - Waterfall
Skógafoss (pronounced [ˈskou.aˌfɔs]) is a waterfall situated on the Skógá River in the south of Iceland
at the cliffs of the former coastline. After the coastline had receded seaward (it is now at a distance of about 5 kilometres (3.1 miles) from Skógar), the former sea cliffs remained, parallel to the coast over hundreds of kilometres, creating together with some mountains a clear border between the coastal lowlands and the Highlands of Iceland.

"The proportions of the human body according to Vitruvius"
Drawing by Leonardo da Vinci around 1490
Da Vinci's Vitruvian Man of Math
James Earle
What's so special about Leonardo da Vinci's Vitruvian Man? With arms outstretched, the man fills the irreconcilable spaces of a circle and a square -- symbolizing the Renaissance-era belief in the mutable nature of humankind. James Earle explains the geometric, religious and philosophical significance of this deceptively simple drawing.

Things You Might Not Know
About Leonardo da Vinci's
Vitruvian Man
BY Kristy Puchko
Leonardo da Vinci's Vitruvian Man
has evolved over the last five centuries from a thoughtful sketch into
the picture of health. But the history behind this sketch is as curious
as its image is omnipresent.
*
1. Leonardo Never Intended For Vitruvian Man To Be Displayed. The sketch was discovered in one of the High Renaissance master's
personal notebooks. The study was simply for the artist’s own
edification, and when he completed it around 1490, he likely never expected it would be admired. Yet today Vitruvian Man is iconic and among the artist's best known works, along with The Last Supper and Mona Lisa.
*
2. It’s Art Meets Science. A true Renaissance man, Leonardo was not only a painter, sculptor,
and writer, but also an inventor, architect, engineer, mathematician and
amateur anatomist. This pen and ink drawing was his exploration of the
theories about human proportions set forth by ancient Roman architect Vitruvius. In his treatise De Architectura, Vitruvius
wrote, "For if a man be placed flat on his back, with his hands and
feet extended, and a pair of compasses centered at his navel, the
fingers and toes of his two hands and feet will touch the circumference
of a circle described therefrom. And just as the human body yields a
circular outline, so too a square figure may be found from it."
*
3. Leonardo Was Not The First To Attempt To Illustrate Vitruvius’s Theories. American scholar Toby Lester explained to NPR
in a 2012 interview, "Especially in the 15th century, in the decades
leading up to Leonardo's own time in drawing, a number of people begin
to try to render that idea in visual form."
*
4. It May Have Been Part of A Collaboration. In 2012, Italian architectural historian Claudio Sgarbi
shared findings that he felt indicated Leonardo's study of proportion
was sparked by a similar one done by his friend and fellow
Vitruvius-enthusiast Giacomo Andrea de Ferrara,
an architect of the time. There’s some debate about whether the pair
worked in tandem, but even if this theory is incorrect, historians agree
Leonardo perfected flaws in its execution where Giacomo failed,
including the second set of arms and legs that allow for a more accurate
depiction of Vitruvius’s writings.
*
5. The Circle and The Square Have A Grander Meaning. In their mathematical explorations, Vitruvius and Leonardo were
looking for not just the ratios of man but of all creation. In a
notebook from 1492, Leonardo mused,
"By the ancients man has been called the world in miniature; and
certainly this name is well bestowed, because, inasmuch as man is
composed of earth, water, air and fire, his body resembles that of the
earth." In other words, man is a microcosm of the universe.
*
6. It’s One of a Series Of Sketches. To improve his art and better understand how the world around him worked, Leonardo drew many people, marking off how their proportions fell.
*
7. Vitruvian Man Is The Male Idea. The identity of the model remains shrouded in mystery, but art
historians believe Leonardo took some liberties in his drawing. This
work was not a portrait as much as a diligent depiction of a perfect
male form designed by math, not shaped by life.
*
8. It Could Be A Self-Portrait.
Going off scant descriptions of the 15th century artist as a younger
man, some art historians have suggested Leonardo himself is his Vitruvian Man
model. As Lester told NPR: "He was described as being very finely
built, strong, very beautiful with locks of hair that curled and went
down to his shoulders. There are a couple of possible renderings of him,
one that survives in a sculpture from Florence and another that's in a
fresco from Milan, and they both look a bit like that figure as well,"
but he admitted there's no way to know "for sure."
*
9. Vitruvian Man Had A Hernia. That's the diagnosis that surgical lecturer Hutan Ashrafian made 521 years after the fact: An inguinal hernia.
Ashrafian further theorized that such an issue could have killed this
Vitruvian Man if Leonardo modeled the figure off of a cadaver, it was
possibly the hernia that did him in.
*
10. You Need The Surrounding Notes For The Full Contex. As the sketch originally appeared in a notebook, Vitruvian Man sat surrounded by handwritten notes regarding its observations about human proportion. Translated to English, they read in part:
"Vitruvius, the architect, says in his work on architecture that the measurements of the human body are distributed by Nature as follows that is that 4 fingers make 1 palm, and 4 palms make 1 foot, 6 palms make 1 cubit; 4 cubits make a man's height. And 4 cubits make one pace and 24 palms make a man; and these measures he used in his buildings. If you open your legs so much as to decrease your height 1/14 and spread and raise your arms till your middle fingers touch the level of the top of your head you must know that the centre of the outspread limbs will be in the navel and the space between the legs will be an equilateral triangle. The length of a man's outspread arms is equal to his height."
*
11. The Body Is Striped With Measurement Line. Look at the man's chest, arms and face. Solid straight lines mark Leonardo's proportions, to which his notes refer. For instance, the ears/bottom of nose to the eyebrows make up a third of the face, while the bottom of the nose to the chin makes up the lowest third, and the eyebrows to the hairline make up the top.
*
12. It Has Other, Less Esoteric Names. The sketch is also called Canon of Properties or Proportions of Man.
*
13. Vitruvian Man Strikes 16 Poses. At first glance, you might only see two: Standing feet together, arms outstretched and standing feet apart arms lifted. But part of the genius of Leonardo's depiction is that the superimposed body allows for views of 16 combinations of these outstretched limbs.
*
14. It Has Been Co-Opted For A Political Message. Reconnecting to Vitruvian Man's relation of man and nature, large-scale artist John Quigley
used the familiar image to illustrate the aggressiveness of global
warming. Pictures of ice melting may not move mercury for many, but by
constructing Melting Vitruvian Man
on a massive ice floe, Quigley was able to give the issue a new scale.
Quigley's copper strip sketch measures four times the size of an Olympic
swimming pool.
*
15. The Original Sketch Is Rarely Seen In Public. Recreations can be found far and wide, but the original is too fragile and important to be on permanent display. Vitruvian Man is typically kept under lock and key at the Gallerie dell'Accademia in Venice. An exhibition held in 2013 offered the first chance in 30 years to see Vitruvian Man.
In its off time, the only way to view Leonardo's sensational sketch is
to request special permission for a private session to the Office of Drawings and Prints.
