Alexander the Great in the Air; Unknown; Regensburg, Bavaria, Germany, Europe; about 1400 – 1410 with addition in 1487; Tempera colors, gold, silver paint, and ink on parchment.

In a scene representing one of the stories from the legend of Alexander the Great most popular in the Middle Ages, the world conqueror, dressed as a European monarch might be, is pulled aloft by a pair of griffins and an angel. They hover precariously over a sea filled with an entertaining variety of fish and other creatures. The artist emphasizes the strange chair's upward movement as it carries the group out of the square framework of the miniature and takes off into the text. 

A Harvest of Death; Timothy H. O’Sullivan, American, about 1840 – 1882, Print by Alexander Gardner, American, born Scotland, 1821 – 1882; negative July 4, 1863; print 1866; Albumen silver print.

Although Gardner's caption identifies the men in the photograph as "rebels represented...without shoes," they are probably Union dead. During the Civil War, shoes were routinely removed from corpses because supplies were scarce and surviving troops needed them. 

The two images I've embedded are from a selection of about twenty assembled at Public Domain Review.

In August of this year The Getty announced the launch of their Open Content Program which sees more than 4500 images from their collection made available under an open license, meaning anyone can share the images freely and without restriction.

A wonderful resource for bloggers and the intellectually curious.
