Wonders in the Deep: Extraordinary Shipwreck Discoveries from Spanish Gold to Shackleton’s Bible by Mensun Bound and Mark Frary is a maritime history that uses shipwrecks and the treasures recovered from them to tell the story of human ambition, trade, exploration and loss — from around 3000 BCE to modern times. Bound, a noted underwater archaeologist who helped lead the expedition to find Shackleton’s Endurance, and Frary guide the reader through objects such as cannonballs, Nazi eagles, ancient helmets, and Chinese porcelain. Each artefact becomes a window into the lives, cultures, conflicts, and ideas of the people who made and used them. Beautifully illustrated, Wonders in the Deep offers not just the thrill of discovery but reflections on how the sea preserves fragments of our past.
