how big is the wanderer above the sea of fog located
Robert Macfarlane discusses the painting in terms of its significant influence on how mountain climbing has been viewed in the Western world since the Romantic era, calling it the “archetypical image of the mountain-climbing visionary”, and describing its power in representing the concept that standing on mountain tops is something to be admired, an idea which barely existed in earlier centuries. 
Some meaning of this work is lost in the translation of its title. In German, the title is “Wanderer über dem Nebelmeer”. Wanderer in German can mean either “wanderer” or “hiker”. 
Freidrich was fascinated with nature and solitude. Later in his career, he combined this passionate interest with his belief in self-expression to create unique paintings that displayed breathtaking scenery and possessed an ambience of repose and serenity, the likes of which can be found in �Wanderer Above the Sea of Fog�.
David d�Angers once said of Caspar David Friedrich, �Here is a man who has discovered the tragedy of landscape.�
Friedrich used landscape as a way of expressing profound experience, and was able to link this to his protestant background. Yet even in his early output, it was clear that his sensibility allowed for a greater array of moods and possibilities than just religious veneration. His later work explored the spiritual side of humankind on a more universal level: face to face with the mystery and loneliness of great landscapes, a pensive glorification of nature in all its sublime and frightening grandeur.
What is he thinking as he stands there? It is natural to make the case for an optimistic interpretation: that he has trekked to the top of this rocky precipice, and now, exalted by his efforts, looks over the entire world — glorious and inspired, elevated and dignified.
The painting is composed of various elements from the Elbe Sandstone Mountains in Saxony and Bohemia, sketched in the field but in accordance with his usual practice, rearranged by Friedrich himself in the studio for the painting. In the background to the right is the Zirkelstein. The mountain in the background to the left could be either the Rosenberg or the Kaltenberg. The group of rocks in front of it represent the Gamrig near Rathen. The rocks on which the traveler stands are a group on the Kaiserkrone.
Wanderer above the Sea of Fog (German: Der Wanderer über dem Nebelmeer), also known as Wanderer above the Mist or Mountaineer in a Misty Landscape, is an oil painting c. 1818 by the German Romantic artist Caspar David Friedrich. It has been considered one of the masterpieces of Romanticism and one of its most representative works. It currently resides in the Kunsthalle Hamburg in Hamburg, Germany.
As the viewer cannot see the figure’s face, the tone is questionable. In line with Friedrich’s other works, and the overall Romantic ideal, it seems fitting to believe that this wanderer stands in awe of the spooky nature before him.
Use of light:
The light seems to be coming up from beneath the rock, somehow illuminating the fog. The rock the mysterious figure stands on remains mostly in silhouette form, though some detail is visible at the top near the figures’ feet.
