History: cannon 28  - SIGA nº 015893

  This colubrina — a type of cannon that served as long-range naval artillery — equipped the Fort São Francisco Xavier de Tabatinga, located on the banks of the Solimões River in the Brazilian state of Amazonas. The fort was built in 1776, one year after the construction of the Forte Real Príncipe da Beira, and was part of a project to occupy and dominate the Amazon territory.

  The Tabatinga Fort dominated the river because it marked the western limit of Portuguese control on the border with Peru and Colombia. However, the geography itself led to the fort’s ruin: erosion by the river on the banks where it was located completely destroyed it in 1932.

  Since that time, deforestation and excessive exploitation of the Amazon rainforest have left considerable signs of damage. In 2022, the forest suffered numerous fires, exceeding the average of the last 15 years; in the month of June alone, there were more than 2430 outbreaks of fire. Timber extraction and the opening of fields for agribusiness and livestock, most of which are illegal, have caused this damage.


  Deforestation — which increased considerably during the pandemic, when the attention of the media was focused on the virus — is the main reason for the spread of fires. At a ministerial meeting in April 2020, the then environment minister Ricardo Salles declared, "We are in this moment of tranquility in the aspect of press coverage, because it only talks about Covid, and the herd goes on. "


  Indigenous lands in the Amazon are affected by fire and smoke. Many loggers and land grabbers work in parts of Rondônia, for instance, on the border with areas where the Karipuna live, and because the Karipuna are so few in number, they are greatly threatened. According to the Public Ministry, in 2019 the Karipuna were at risk of genocide. Even today the community struggles to preserve its existence in isolation.

Note: Colubrina is a type of cannon that served as long-range naval artillery. The cannon 31 (smell Absence) also equipped the Tabatinga Fort.

smell Anoxia PB00495C

  Anoxia is a disquieting smell of the unknown.
It approaches without our realizing its consequences.
In our daily lives, we breathe a combination of sulfuric notes and esters in concentrations that are almost imperceptible.

But in high doses, these same ingredients can lead to a lack of oxygen, known as anoxia.


  This smell has the odor of bacteria, which have sometimes been used as a weapon of war and can cause lung diseases, resulting in dyspnea. Also present is anxiety about possible shortness of breath, a symptom of Covid 19. In order for the bacteria to be felt through the nose, we used thiazole, a heterocyclic compound that contains both sulfur and nitrogen. The term  also refers to a large family of derivatives.
