heroínas à parte...os musgos chegam a Cannes


Ernst Heinrich Philipp August Haeckel (Potsdam, 16 de Fevereiro de 1834 — Jena, 9 de Agosto de 1919) foi um naturalista alemão que ajudou a popularizar o trabalho de Charles Darwin e um dos grandes expoentes do cientismo positivista.[1] Foi médico e um artista versado em ilustração que se tornaria professor em anatomia comparada. Foi dos primeiros a considerar a psicologia como um ramo da fisiologia. Propôs alguns termos utilizados frequentemente como filo e ecologia. Os seus principais interesses recairam nos processos evolutivos e de desenvolvimento e na ilustração centífica. O seu livro Kunstformen der Natur é um conjunto de ilustrações de diversos grupos de seres vivos.

seara em foice alheia

o Senhor Escher gostava de jardins criptogamicos!

``Below the mill is a garden of bizarre, giant plants. This is actually a magnified view of a cluster of moss and lichen which Escher drew in ink as a study in 1942.``

Waterfall is a lithography print by the Dutch artist M. C. Escher which was first printed in October, 1961. It shows an apparent paradox where water from the base of a waterfall appears to run uphill before reaching the top of the waterfall.

While most two-dimensional artists use relative proportions to create an illusion of depth, Escher here and elsewhere uses conflicting proportions to create the visual paradox. Waterfall has the structure of a Penrose triangle, an impossible object designed independently by Roger Penrose and Oscar Reutersvärd.

The image depicts a village or small city with an elevated aqueduct and waterwheel as the main feature. The aqueduct begins at the waterwheel and flows behind it. The walls of the aqueduct step downward, suggesting that it slopes downhill. The aqueduct turns sharply three times, first to the left, then straight forward and finally to the left again. The viewer looks down at the scene diagonally, which means that from the viewer's perspective the aqueduct appears to be slanted upward. The viewer is also looking across the scene diagonally from the lower right, which means that from the viewer's perspective the two left-hand turns are directly in line with each other, while the waterwheel, the forward turn and the end of the aqueduct are all in line. The second left-hand turn is supported by pillars from the first, while the other two corners are supported by a tower of pillars that begins at the waterwheel. The water falls off the edge of the aqueduct and over the waterwheel in an infinite cycle; in his notes on the picture, Escher points out that some water must be periodically added to this apparent perpetual motion machine to compensate for evaporation. The two support towers continue above the aqueduct and are topped by two compound polyhedra. The one on the left is a compound of three cubes. The one on the right is a stellation of a rhombic dodecahedron (or a compound of three non-regular octahedra).

the dots on the wall

This is the Diga del Cingino dam in Italy -
But look closer... See spots on the dam wall?

They are European Ibex and they like to eat the moss and lichen

& lick the salt off the dam wall.
