The First Day
Galileo Galilei
In a time when empirical observation was seen as subversive, Galileo admires Aristarchus and Copernicus for daring to trust reason over their own senses. Their boldness challenged a world where celestial truths were dictated by tradition and scripture. Galileo's commentary underscores the tension between evolving scientific thought and the rigid orthodoxy he himself would confront—culminating in his trial and forced recantation in 1633.
