This drawing shows a frog skeleton in a twisted pose, lying on its side. The bones are drawn with fine, precise lines, showing every joint and tiny detail. Above it, there’s a short line of Latin text in neat letters. The artist focused on how bones bend and connect, almost like a puzzle. This kind of close-up study was rare at the time. Next, look up etching to see how this technique works.
