It appears there may be a misunderstanding. There is no historical record of Nigerian artists, let alone those with names starting with 'Q,' dating back to the 5th century.

Art history, especially from that period in Nigeria, is a complex and ongoing field of study. While archaeological discoveries continue to shed light on ancient civilizations and their cultural practices, concrete information about individual artists from such an early period is scarce.

However, we can still explore some fascinating aspects of Nigerian art history!
