Nothing but the hits! Proceeding with my list in no logical order we have:
15) The hunters in the snow, by Pieter the elder Breugel 1525-1569
The first of the three Breugels in Flemish painting, Pieter was father to Jan and Pieter the younger. This painting is a haunting vision of life in medieval times. Influenced by Hieronymus Bosch Breugel did many paintings of peasant life. He actually dressed as a peasant in order to study their taverns and weddings, and daily life. There is a charm and sometimes almost Rockwellian coziness in his paintings.
16) The Arnolfini portrait Jan van Eyck before 1395 - 1441
This is a very early oil painting. Sometimes Van Eyck has been credited with inventing oil painting, however that is not so. However he perfected the art and helped to popularize its use. This painting has been analyzed many times, and every few years its interpretations are revised.
It has been suggested that the bride looks pregnant and more recently that she died just before or during the time the picture was painted. This is a rather small painting and the level of finish and detail is amazing.
17) Woman holding a balance, Johannes Vermeer 1632?- 1675
Vermeer was rediscovered in the 19th century. So little was know about him that he was called the Sphinx of Delft. Recently scholarship has revealed more. The natural look of his paintings and his close observation of the actual appearance of form in the play of light gives these paintings a look of quiet perfection. I could have selected any of a number of Vermeers including one or two that are better known, but I have always liked this one. There has been much talk in recent years about his possible use of a camera obscura, a device like a camera containing no film, to make his paintings. Other art historians disagree. This has been presented in the press as a sort of scandal. Even if he used the device it still doesn't explain his paintings. Anyone can acquire one, but no one else seems to be able to make anything of the quality of Vermeer using one.
