Books
Step-by-step explanation:
By 1500, Renaissance ideas were mainly being spread across Europe through books.
One of the greatest achievements made in the Renaissance time was the innovation of the printing press which brings life into arts, thoughts, and science.
The printing press was invented by a goldsmith called Johann Gutenburg in Germany around 1400. The printing press spread within 200 cities in European countries.
By 1500, the printing press in Western Europe had already produced millions of printed books. By 1600, the books produced can be projected to be between 150 to 200 million.
