History of Sponging

History of Sponging

Although sponge diving was a source of income for several Greek islands during the last centuries, Kalymnos is known to be the center of the Greek sponge diving industry. The waters around the Greek islands are very suitable for the sponges to grow, because of the high temperature. The best sponge quality is found in the southeast of the Mediterranean sea.Although this was very hard work, this way of diving brought so many sponges to the island that the trade from Kalymnos expanded in a great way around 1800. Half-way the 19-th century Kalymnos had several merchants that became very wealthy. Through the big profits they made on the sponges they also gained a big influence on the social life on the island.In her book "Bitter Sea", Faith Warn discribes that in 1868 the sponge diving fleet consisted of:

  • 300 ships with divers (6 to 15 divers on each ship)
  • 70 ships that harvested sponges with harpoons
  • 70 trawlers

  • This was also of big influence on all the people on Kalymnos. Every family had fathers, sons, brothers or other relatives that were paralised or never returned from the sponge diving season. By the end of the 19th century this caused big anxiety on Kalymnos, especially among women. In those days Kalymnos was ocupied by the Turks. The women asked the Turkish sultan to forbid the standard diving suit, which he did in 1882. Profits dropped: the divers had to go "skin diving" again. About 4 years later the suit was back and so were the decompression accidents.

  • Sponge diving brought wealth to the island but took a lot of lives as well. In the beginning only the merchants profited from it, later the whole community. Health care and education came available for everybody for free. The merchants posessed the fleet, the factories, restaurants, bars and a factory on Kalymnos were standard diving equipment was produced. English standard diving equipment was copied. Thus, the equipment was cheap and easy to maintain and repair. Spare parts were available on their own island. The "Xyth Pio" factory produced standard diving equipment for many years.

In the beginning of the 20st century the sponge diving industry had hard times in the Dodekanesos. Around 1900 the growth got to her maximum and both worldwars caused limitations to the trade. From Kalymnos and other islands like Halki and Symi large groups of divers settled in other parts of the world to do what they did best: diving. Around 1905 a group of about 500 divers from the Dodekanesos settled in Tarpon Springs, Florida, USA. These days diving helmets are still made by Nicolas Toth. Nic is the grandson of Antonios Lerios, born on Kalymnos, who settled in Florida in 1913 as a helmet maker.

After the second world war the sponge diving industry almost completely stopped in the Dodekanesos. In those days Australia refused to work together with Japanese divers in the pearl industry. Therefore many Greek divers settled in Australia.  Many people feel that the introduction of the synthetic sponge ment the end for the sponge diving industry. The biggest problem however, occured in 1986. Nearly all the sponges in the Aegean sea turned out to be infected. The cause of this never became clear. A sudden rise of the water temperature could be the cause. Similar infections appeard in the Gulf of Mexico in the 1940's 70's and 90's.  Anno 2001 there is hardly anything left of the sponge diving fleet from 1868. From 400 ships, about 10 to 15 are left. In recent years the sponges in the waters around Kalymnos have recovered in a great way. However, local sponge divers announced that they encountered infected sponges again in october 2000.

Some sponge diving witnesses can be found on some Greek islands. The capital of Kalymnos, Pothia, has a number of workshops left were sponges are cut and sold. In the harbour, a nautical museum has a display on sponge diving. The helmets you see in the previous page are in this exhibition. Vlihadia, a little town close to Pothia holds the "Sea World Museum". The privat collection of the Valsamidi brothers.  

Sponge diver in full action. The use of standard diving equipment stopped in the 1970's. Many helmets were then sold as scrap-iron ! Still there are some divers in the sponge diving business. They now wear neoprene suits and a diving mask. They hold a mouthpiece between their teeth. This is attached to a air hose that leads to a compressor on the boat.  
One of the many sponge shops you can still find on Kalymnos today. Due to pollution and huge harvesting there are hardly any Mediterranean sponges left. Tourists go home with the higher quality (and more expensive) Greek sponges or with Caribbean and Philippinean sponges that the Greeks import to sell.

If you want to know more about Greek sponge diving and about the effects that it had on the community of Kalymnos we would like to recommend two books:

Mrs. Charmian Clift & Mr. George Johnston (1955), The sponge divers, pub. Lond. Collins. (Fiction !)

Warn, Faith (2000), Bitter Sea, The real story of Greek Sponge Diving, Guardian Angel Press, South Woodham Ferrers. (Non-fiction, many good facts and photos)
