Create a multi-panel collage that embodies the essence of the Renaissance period. The left panel exhibits a bustling marketplace with merchants and customers of diverse descent and various genders busily exchanging goods, against the backdrop of ornate, domed buildings inspired by the architecture of the time. The center panel showcases a group of intellectuals from different descents, both men and women, engaged in a heated philosophical discussion within the confines of a library filled with parchment rolls and antiquated books. The right panel portrays creatively designed Renaissance-era inventions such as the printing press, an ornamental astrolabe, and an intricate mechanical clock. Interweaving all the panels should be allegorical figures reflecting the resurgence of classical knowledge and thought, which was a hallmark of this era.
