It appears there may be a slight hiccup in your request!

You see, while Colombian art is vibrant and ancient, it doesn’t quite stretch back to the 7th century. The pre-Columbian civilizations of Colombia flourished much earlier, with their artistic expressions reaching peaks during periods like the Muisca civilization (6th - 16th centuries) or the Tayrona culture (500 - 1600 CE).

Furthermore, finding a Colombian artist from that era whose English name starts with ‘Z’ is going to be nearly impossible. Artistic attribution in ancient cultures wasn’t typically done in the way we understand it today, and records from those times are scarce.

However, I can certainly still help you explore Colombian art! Perhaps you’d like to:

• Learn about a specific pre-Columbian civilization in Colombia, such as the Muisca or Tayrona?
• Discover examples of iconic goldwork or pottery from ancient Colombia?
• Explore how contemporary Colombian artists are reinterpreting their cultural heritage?

Let me know what sparks your interest, and I’ll gladly delve into the fascinating world of Colombian art with you!
