The image is a vintage, black and white photograph of a microscopic organism, likely a type of radiolarian or similar marine life. The organism is centered within a circular frame, resembling a view through a microscope. It has a complex, elongated body with radiating spines or filaments extending outwards. The body appears somewhat translucent, with darker areas suggesting internal structures. The background is a pale, diffused tone, typical of early microscopic photography. Below the image, there is text that reads "FASTIGIUM ARYN" and "OCTOBER, 1894". In the bottom right corner, there is a small "P.L.". The overall aesthetic is reminiscent of scientific illustrations from the late 19th or early 20th century.
