Třeboň Altarpiece and its loose brushwork and elegant, rhythmical forms. At some point the work was broken up, with two surviving panels in the National Gallery, Prague, and a third in the Alsová Jihoceská Galeria, Hluboká nad Vltavou, Czech Republic. The extant panels are "The Agony in the Garden", "Entombment" and the "Resurrection". The reverse of the "Agony" shows languid, touching, "rosy-cheeked" representations of Saints Catherine, Mary Magdalene and Margaret. It is not known how many panels made up the original altarpiece, or how they were arranged. A total five is considered the most likely number, which would allow for four wings
Hinged dissection Hinged dissection A hinged dissection, also known as a swing-hinged dissection or Dudeney dissection, is a kind of geometric dissection in which all of the pieces are connected into a chain by "hinged" points, such that the rearrangement from one figure to another can be carried out by swinging the chain continuously, without severing any of the connections. Typically, it is assumed that the pieces are allowed to overlap in the folding and unfolding process; this is sometimes called the "wobbly-hinged" model of hinged dissection. The concept of hinged dissections was popularised by the author of mathematical puzzles, Henry Dudeney.
