Final answer:
The invention that allowed the dissemination of knowledge during the Renaissance was the Printing Press, developed by Johannes Gutenberg, enabling the mass production of texts.
Step-by-step explanation:
The invention during the Italian Renaissance that allowed the reintroduction of classical knowledge and the emergence of new learning to spread throughout Europe was the Printing Press.
Johannes Gutenberg, a German goldsmith, innovated upon earlier Chinese printing techniques to create a system of moveable type that was particularly efficient for European languages. This technology vastly increased the availability and distribution of both classical and contemporary works, greatly facilitating the spread of Renaissance humanism, fostering skepticism about religious authority, and contributing significantly to the eventual rise of the scientific revolution.
Gutenberg's first major printing work was the Gutenberg Bible, completed around 1455, which was among the earliest books printed using his new press technology. The printing press not only facilitated the rediscovery of ancient texts but also allowed individuals like Martin Luther to spread their ideas widely, challenging established beliefs and contributing to significant cultural and intellectual shifts.
