What would you definition of this be?
In der deutschen Übersetzung wird mir "intellektuelle Fähigkeiten" angezeigt.
Dieser Begriff steht in Bezug zu Wörtern wie "Intelligenz, Talent, Verstand, Geist".
An intellectual prowess is a display of exceptionally high intelligence and knowledge. To be highly skilled, knowledgeable at/of something.
Prowess often has a negative connotation though. A person who is self-centered or a braggart may be said to be speaking of their prowess in something, to include intellect. When others speak of prowess it is often satirically said.
A more positive statement might be intellectual capability, capacity and so forth.
Someone who goes to a nudist beach and remembers faces afterwards.
If somebody is far from being good-looking you may praise their intelectual prowess
