This is an insect observation jar featuring a metal base marked with the emblem of a “Gallic rooster,” symbolising France, and the French inscription “MODELE DÉPOSÉ” (registered design). The jar’s top includes a detachable magnifying glass, allowing for detailed observation of insects placed inside. The glass body of the jar also permits viewing of the insects from the side. Upon closer inspection, the glass contains numerous tiny air bubbles, indicating that it was likely crafted using traditional hand-blown techniques.
“MODÈLE DÉPOSÉ” – This phrase is specific to French design law and was widely used from the mid-19th century onward to indicate a registered industrial design. It is especially common on consumer and educational objects made in France.
Gallic rooster emblem – The rooster became a prominent national symbol during the French Third Republic (1870–1940) and was frequently used on domestically produced goods, particularly those associated with education, science, or civic pride.
Hand-blown glass with visible air bubbles strongly suggests pre-industrial or semi-industrial production, by the 1920s, machine-made glass had largely eliminated these imperfections in mass-market objects, and the metal construction (likely brass or nickel-plated brass) and fine threading are consistent with late 19th-century craftsmanship.
Based on these 3 facts, it is likely that this insect observation magnifying jar was made around the year AD 1880–1910.
When discussing France and insects, the world-renowned entomologist Jean-Henri Fabre naturally comes to mind. Born in AD 1823 in the southern French province of Aveyron, Fabre grew up in a modest household and had to leave school to work. Despite these challenges, he earned a degree from the Paris Academy of Sciences through persistent self-study while working. At the age of 45, Fabre purchased a plot of land in the village of Sérignan in southern France, naming it the “Harmas,” where he conducted meticulous observations and studies of insects.
In AD 1877, Fabre experienced the tragic loss of his 16-year-old son Jules, who shared a similar temperament to his own. The following year, at the age of 55, Fabre channelled his grief into writing and published the first volume of Souvenirs Entomologiques (The Life of Insects). He completed the tenth and final volume at the age of 83. After the publication of Souvenirs Entomologiques, Fabre gained widespread acclaim both domestically and internationally. However, he remained devoted to his passion for insects, continuing his observations and research until his death in AD 1915 at the age of 91.
