History cannon 28  | 015893

  This colubrine equipped the Fort São Francisco Xavier de Tabatinga situated on the banks of the Solimões River in Amazonas State in Brazil. The Fort was erected in 1776, a year after the construction of the Fort Real Príncipe da Beira, and was also part of a project of occupation and domination of the Amazon. The Fort Tabatinga marked the western border under the Portuguese crown exactly at the dividing line among Brazil, Peru and Colombia. However, geography itself led to its destruction due to river erosion destroying it in 1932. Two cannons from this fort were brought to the Museu Histórico Nacional and the others were buried in the bottom of the Solimões River.

  Since that time, it is possible to notice signs of deforestation and excessive exploitation of the Amazon rainforest, known worldwide as the “lung of the world”. However, this definition is not correct because the forest consumes almost all the oxygen it produces. The main responsibility for the production of oxygen on the planet lies in the ocean's algae and phytoplankton. Nowadays there is a crisis in the levels of marine oxygen due to pollution provoked the expansion of forest fires.


  In 2020, the Amazon rainforest suffered fires that exceeded the average of the last 13 years, increasing 28% in comparison with July, 2019. The reasons involve the illegal logging and opening of fields for agribusiness and livestock. Deforestation is a major reason for the spread of fires and it has increased with the global pandemic due to a diversion of attention from the media and authorities to the Covid19.


  The results of the fires independently of their causes, is terrifying to the Indigenous communities who have their villages affected by smoke also affecting fauna and flora. The shortness of breath caused by the smoke in the lungs is similar to urban cities and shared by the whole world. Respiratory diseases have escalated as the new coronavirus spreads through the Amazonian area. Could it be that Mother Nature is screaming to the human crisis we are experiencing?

Curiosity: Colubrine is a type of cannon that used to serve as a long distance naval artillery. The cannon 31 Absence also armed Tabatinga Fort.

smell Anoxia

  A disturbing unknown smell. An odor that approaches us without giving a sign of its consequences. We wanted to create a bacterial odor used as a weapon of war and as
a possible cause of dyspnea. We added a note of anxiety about a possible shortness of breath, one of the symptoms of Covid19.


  We breathe a combination of sulfuric notes and esters in almost imperceptible concentrations in our daily lives. However, these same ingredients overdosed can lead to
a lack of oxygen known as anoxia. 


  In order for the bacteria to be felt through the nose, we added Tiazol, a heterocyclic compound that contains both sulfur and nitrogen.  The term 'thiazole' also refers to a large family of derivatives named thiazole ring, also a component of the vitamin thiamine (B1). We didn't think of adding literally the lack of air produced by the Amazon rainforest burnings. We created a broad-ranging smell to remind us
of a premonition of anoxia.


That is the cannon’s history and the reasons 
it is associated with the smell Anoxia
These questions are bridges between you and 
passages of Brazilian History - past and present.
Contribute in the construction of the 
smell's collective imagination.
Anoxia is the absence of oxygen.
In the absence of breath,
what would be the carrier of the smells?
In a hypothetical situation of not being able
to breathe anymore, which smell
would you miss the most?
