Leaping black cat with botanical anatomy on parchment

Vintage scientific illustration and anatomical drawing on aged, textured parchment paper. Center subject: a sleek, majestic black cat in a dynamic, graceful leaping pose, rendered with incredibly fine, detailed black ink lines capturing every strand of fur. The cat's lower body and tail seamlessly blend into an arrangement of intricate, highly detailed black-and-white botanical flowers (large anemones and ferns). The background features faded golden-brown geometric diagrams: concentric circles, radial lines, compass markings, and tiny handwritten measurement notes, resembling an antique astronomical or alchemical chart. Monochrome ink with sepia accents, high contrast, mystical and scholarly aesthetic. In the bottom right corner, a small, elegant handwritten signature "Fotkelis".
