A voyager or traveler of knowledge, understanding and learning. Aka, an academic, scholar, or other knowledge-seeking individual. Comes from the Greek episteme--meaning knowledge, and the also Greek nautes--meaning sailor. Similar (and inspired by) astronaut. (From the Greek astron--star, and nautes--sailor, (again).

A much better term for a geek or bookworm.

Appropriate for resumes and embroidered pillows.

Not to be confused with pistenaut, which means sailor of urine. Comes from... well.
