Together with the Greek Education Ministry and the Royal Hellenic Navy, the sponge divers salvaged numerous artifacts from the waters. By the middle of 1901, divers had recovered bronze statues, one named "The Philosopher", the Youth of Antikythera (Ephebe) of c. 340 BC, and thirty-six marble sculptures including Hercules, Ulysses, Diomedes, Hermes, Apollo, three marble statues of horses (a fourth was dropped during recovery and was lost on the sea floor), a bronze lyre, and several pieces of glasswork. Recovered ship's equipment included lead scupper pipes and hull sheeting, and a set of lead sounding weights weighing 6 and 14 kg. These are the only sounding weights ever discovered on an ancient shipwreck in the Aegean, although comparable examples have been recovered along the Levantine coast. Many other small and common artifacts also were found, and the entire assemblage was taken to the National Archaeological Museum in Athens. The death of diver Giorgos Kritikos and the paralysis of two others due to decompression sickness put an end to work at the site during the summer of 1901.
