Final answer:
Chicho studied astronomy due to his father's discouragement of an art career, a common dilemma for many aspiring artists. Marc Chagall and Jose Clemente Orozco also faced challenges but ultimately embraced their artistic passions and became renowned for their works.
Step-by-step explanation:
When Chicho faced the reality that pursuing an art career was discouraged by his father, he directed his efforts into the study of astronomy, learning the Chinese works on the subject. His situation was not unique; many would-be artists have faced similar crossroads. The renowned artist Marc Chagall, for instance, originally excluded from public schooling due to being Jewish, managed to attend school and eventually moved to Saint Petersburg to broaden his horizons in art. Another example, Jose Clemente Orozco, was encouraged to study at an agricultural school, yet after an accident, he found solace and purpose in painting. Both Chagall and Orozco serve as historical precedents to the struggle of following an artistic calling in the face of adversity, illustrating that passion for art can prevail even when one's original intentions are stifled.
