Or a technology at the peak of its influence. Railroads were a huge thing, but peaked in terms of geopolitical influence in about 100 years. Same with modern highways, telephones, telegraph machines, etc. Maybe bioengineering is the next big thing. That will probably peak in 100 years too. Edit: which civilization are you attributing the voyage to? The Phoenicians were past their peak. The Egyptians were at their peak, but they basically were cutting a check.
