from Wikipedia, the free encyclopedia
Regula (No. 10)

The regula ( Latin , plural regulae ), the Doric drop bar , is a small plate with usually six hanging conical or cylindrical drops, the guttae , under the protruding bar ( taenia ) of the architrave of the Doric order .

The regulations correspond to the triglyphs of the Doric triglyph frieze. In the early phase of Doric stone architecture, the number of its guttae could only be four, only in the second half of the 6th century BC. BC the number of six guttae became binding. With the 3rd century BC The mixing of the column orders , which began in BC, was able to decorate a regula including drops, however, also the underside of Ionic Kymatien , as it is often to be found in Alexandrian architecture.
