History of Strapon

Due to the often taboo nature of strap-on activities, information on their history is difficult to find. An 1899 report by Haberlandt documented current and historical use of double-ended dildos in Zanzibar, and is one of the few historical documents of this kind. Female-female dildo usage in ancient China has been documented, but it is not clear if this was double-dildos, strap-on dildos, or just a simple dildo being used by one woman on another. In ancient Greece, dildos were made of stone or padded leather, and some evidence shows aforementioned leather was used to make a harness as well, with olive oil used for anal penetration. A double-penetration dildo was found in ancient France, but its use is lost to time. A 19th century Chinese painting shows a woman using a dildo strapped to her shoe, showing that creative use of strap-ons was already well under way. Many artifacts from the Upper Paleolithic have been found that appear to be dildos, including a double "baton" with a hole in the middle, theorized to be for a strap to hold it to a wearer. The Kama Sutra includes mention of dildos (darshildo in Hindi) made from a wide variety of materials, and used by hand, with ties (straps), or in a harness. It is likely the history of the strap-on parallels the history of the dildo, and given the age of many discoveries, is a rather long history.
