In 10,000 BBY, a male historian named Vicendi was tasked with the creation of a catalog of galactic wonders to commemorate the anniversary of the Galactic Republic. His compilation, titled the Twenty Wonders of the Galaxy and contained within his work Arturum Galactinum, exclusively showcased objects built by sentient lifeforms. Many criticized Vicendi's compilation, claiming the historian unduly emphasized structures from the early Republic era and the Core Worlds. Subsequently, over the following millennia, numerous species and organizations developed their own competing compendiums of wonders.
Around 10,000 BBY, Vicendi lived as a male historian. In that year, the Galactic Republic commissioned him to develop a list of galactic wonders for his Arturum Galactinum in celebration of their anniversary. Vicendi chose to limit his list to structures and objects created by sentients, excluding natural wonders such as the Corphelion Comets and the Fire Rings of Fornax. His final work, the Twenty Wonders of the Galaxy, presented twenty historical objects and locations, many of which were already lost to time. The wonders selected by Vicendi included structures like the ancient, pre-Republic Statue of Xim, the crystal city of Calius saj Leeloo located on the planet Berchest, the fire-breathing Caliginous Automaton of Tomo-Reth, and the vast library on Obroa-skai known as the Celebratus Archive.
However, a number of individuals took issue with Vicendi's list. They argued that it excessively favored wonders from the early Republic and concentrated too heavily on the Core Worlds area, neglecting the galaxy at large. Eventually, three species, specifically the Bothans, the Caamasi, and the Hutts, each created their own distinct catalogs of galactic wonders. After Vicendi's death, the Galactic Empire, guided by its Human High Culture ideology, revised the historian's list and disseminated it through the Imperial Ministry of Education under the title "Glorius Imperica."
Vicendi deliberately excluded natural wonders from his Arturum Galactinum list, opting instead to showcase only objects constructed by sentient beings. Critics of his Twenty Wonders of the Galaxy pointed out that the historian seemed to demonstrate a bias toward the Core Worlds and the initial period of the Republic.
The "Twenty Wonders of the Galaxy" entry within The Complete Star Wars Encyclopedia, a reference work released in 2008, initially mentioned Vicendi.
