Are you thinking of ancient Greek statuary?

Mentioning previous postings is not intended to discourage more discussion -- further questions, discussion, and debate is always welcome.

The FAQ has a section on Ancient art at https://www.reddit.com/r/AskHistorians/wiki/art#wiki_ancient_art . The applicable article is "Ancient Greek men thought the ideal male body possessed a small penis. Do we have any idea what Greek women thought?" at https://www.reddit.com/r/AskHistorians/comments/513rl2/ancient_greek_men_thought_the_ideal_male_body/ . The most pertinent answer is from /u/PapiriusCursor with a massive throbbing 1,993 karma points, but there are also valuable contributions from /u/0x52-0x48 , /u/DrCaptainFantastic , QuintusSertorius , and others. And the stickied "all" warning by commiespaceinvader is well worth reading -- it's small but perfectly formed.

There is this other previous discussion, though of smaller value after reading the above.

"Why do Greco-Roman sculptures of men have such small penises?", https://www.reddit.com/r/AskHistorians/comments/268j4q/why_do_grecoroman_sculptures_of_men_have_such/ , from Ragleur.

The above replies covered all the info in the other hits that I found.
