It is interesting to note that many of the terms used for defecation in ancient Greek are still in use in the modern Greek language.21This seems to be a reference to A.N. Angelakis et al., "Urban wastewater and stormwater technologies in ancient Greece," Water Research 39 (2005) 210–220, but I don't see any mention of "terms used for defecation" in that article.
