Oroboros picture of the month
The Oroboros in Applied Chemistry.An ouroborand is presented in the publication by Durola and Rebek (2010), which in its cavity coordinates an internal side chain and looks to swallow its own tail. The form is caused by the presence or absence of zinc(II) in solution, which flips the cavity between open and closed states (see https://doi.org/10.1002/anie.200906753).
Johann Conrad Barchusen, towards the tail end of alchemy's golden period, attempted to elucidate alchemy's allegorical imagery by detailing the procedures as plainly as he could. He paired the enigmatic photos with the chemical equipment utilized in the technique. (Plate 504, Figures 10-13 from Johann Conrad Barchusen's Elementa chemiae)

Dalí's Ouroboros. "Dalí's Ouroboros is more naturalistic than his other prints in Alchimie des Philosophes, and its features are similar to an eel or sea serpent. It is cut in many pieces, though the head biting the tail remains one piece. The Ouroboros maintains its circular shape, though the oozing pieces of the serpent interrupt its sense of eternity. The decaying pieces also represent the alchemical stage of putrefaction, when the alchemical matter decomposes. The pieces are arranged around a large, circular gem. Each facet of the jewel contains a different symbol, including keys and ants. Dalí frequently used ants as symbols of decay and temporality. In this sense, the ants are fitting in their placements around the dead Ouroboros, a symbol of eternity now subjected to the effects of time. The center features an interlocking Yin and Yang. However, the shapes seem intentionally ambiguous, and also resemble slabs of meat similar to the pieces of the serpent."

Oroboros in Italy. During his vacation in Soave, Italy, our Team member Maximilian discovered an Oroboros on a stone plaque placed on the garden wall of Casa Scrinzi.
Ouroboros was and is the name for the Great World Serpent, encircling the earth. The word 'Ouroboros' is really a term that describes a similar symbol that has been cross-pollinated from many different cultures. From "Ouroboros," there is the serpent or dragon gnawing at its own tail. The symbolic connotation from this owes to the returning cyclical nature of the seasons; the oscillations of the night sky; self-fecundation; truth and cognition complete; the potential before the spark of creation; the undifferentiated; the Totality; and the idea of the beginning and the end as being a continuous unending principle. It represents the conflict of life as well in that life comes out of life and death. 'My end is my beginning.' In a sense life feeds off itself, thus there are good and bad connotations that can be drawn. It is a single image with the entire actions of a life cycle - it begets, weds, impregnates, and slays itself, but in a cyclical sense, rather than linear. Thus, it fashions our lives to a totality more towards what it may really be - a series of movements that repeat. "As Above, So Below" - we are born from nature, and we mirror it because it is what man wholly is a part of. (Copyright © 1997. John N. Harris, M.A.(CMNS))
The sun god and the Ouroboros, image on a golden shrine in the tomb of Tutankhamun. The Ouroboros first appeared in its classical, circular form on a golden shrine in the tomb of Tutankhamun, the pharaoh who, at the end of the revolutionary Amarna Period, returned to Thebes and the traditional religion.

Oroboros in the world of music. While going through some new music, our customer and colleague Prof. Joseph Vincent spotted an Oroboros on a album cover of the band "WookieFoot" and send it to us. Thank you for that!
Full Circle. This image was created for the cover of an issue of Angewandte Chemie that featured an article on the geometric and electronic connections between different types of pericyclic reactions. The background is a page from Woodward and Hoffmann's classic Conservation of Orbital Symmetry. The circle is an orobouros - a mythical serpent eating its own tail - that I created in response to a suggestion by Roald Hoffmann; it is meant to emphasize both the cyclic nature of pericyclic transition structures as well as the fact that the article accompanying this illustration marked Roald's return to the topic of simple pericyclic reactions of hydrocarbons, nearly three decades after he first described many of their key electronic features.

Ouroboros by Lucas Jennis, in the 1625 alchemical tract De Lapide Philosophico. Ouroboros, a mythical dragon-snake that eats up itself, speaks to the cyclic nature of all things. Image of reflection and attentive reasoning, the Ouroboros can be related with each one of those things that, after having reached their end, start again, in an endless return.

Ouroboros and Alexander von Humboldt - From: Olaf Breidbach (2006) "Visions of Nature: The Art and Science of Ernst Haeckel". Prestel, Munich, Berlin, London, New York, page 52. Alexander von Humboldt thought an approach to science was needed that could account for the harmony of nature among the diversity of the physical world. For Humboldt, "the unity of nature" meant that it was the interrelation of all physical sciences—such as the conjoining between biology, meteorology and geology—that determined where specific plants grew. He found these relationships by unravelling myriad, painstakingly collected data

M. C. Escher: Dragon (wood-engraving, 1952). 'However much this dragon tries to be spatial, he remains completely flat. Two incisions are made in the paper on which he is printed. Then it is folded in such a way as to leave two square openings. But this dragon is an obstinate beast, and in spite of his two dimensions he persists in assuming that he has three; so he sticks his head through one of the holes and his tail through the other.
Cosmic Ouroboros By Adams and Primack Scalometer. Phycisist Prof. Joel Primack and his wife, lawyer/philosophe Nancy Abrams, also use the ouroboros to visually describe quantum and cosmic realtionships.

Codex Marcianus - offers one of the best Ouroboros representations.It is the most ancient and complete among greek manuscripts examinated by Marcelin Berthelot in his “ Collection des Anciens Alchimistes Grecs” Paris 1887, Collection of Ancient Greek Alchemists. In the treatise on Chrysopeia, namely by Cleopatra, Berthelot found an entire page with symbols together with the Ouroboros we are examining. Find out more here.
The snake eating its own tail simply represents the recreation of life through death by the Universe. It is interpreted as some kind of a rebirth of the dead reaching an immortality of sorts. Therefore, it is assumed that the infinity symbol was derived from the original symbol of ouroboros. - mythologian.net
