When was infinity first accepted in the west?

Infinity was first accepted in the West during the late medieval period, particularly with the work of mathematicians like John Wallis in the 17th century. Wallis introduced the symbol ∞ in 1655, which helped formalize the concept in mathematical discussions. The acceptance of infinity further gained momentum with the development of calculus by Isaac newton and Gottfried Wilhelm Leibniz in the late 17th century, where concepts of limits and infinite series became integral to the field.
