A slightly exagerrated frontal muscular anatomical drawing.  Presumably, JUST THIS KIND OF THING was what Gibbon was meaning to avoid when talking about specific details of his male/female friends appearances.  Gibbon definitely felt talking about the firmness of a mans calves was - too much information.  Luckily for us Sidonius Appolinaris did NOT hold the same opinion, and we have a detailed (but embarrassing to Gibbon)  description of the Visigothic King Theodoric saved in one of Sidonius's letters
