Tractors and phystics

Agate presents its current favorite.
Within our collections, numerous illustrations or photographs deserve to be exhibited for their aesthetic quality or originality. Today, let's take a lesson in physics with a drawing illustrating the effort required to move a tractor alone on sloping ground.

    New titles will soon join Agate's collections, books, images and magazines. One of them, C. Arnould's "Calendar of the Beekeeper" published in 1908, offers beautiful and humorous illustrations. Our favourite is this cycling bee, a mode of transport so fashionable at the beginning of the 20th century when this book was published.

    Ridgeline in the Mercantour

    Agate presents its current favorite.
    Let’s explore in images a stunning ridgeline in the Mercantour (Alpes-de-Haute-Provence). Through this photograph, part of a documentary series on the French Alps, a wild and unspoiled landscape unfolds, where light and terrain shape a timeless scene. A suspended moment, capturing the vision of Félix Briot (1845-1926), inspector of Water and Forests, and author of several studies and articles on mountain regions.
