Question

In what European cities, and in what languages, was the letter published in 1493?

Answer 1

I'm going to assume that your talking about the letter that Christopher Columbus created after his discoveries. He arrived back at Spain in 1493. Immediately after, he wrote a letter describing what he had discovered during that trip. This letter was written in Spanish, later published in Latin. This letter was written and published in the city of Barcelona.
