Although this post was meant to showcase only the spectacular stained glass window, the following comment by Ricardo Martine Tanoira deserves to be translated & placed here:
My great-grandfather, Carlos Zamboni, was the son of Silvestre Zamboni, founder of an ironworks in Buenos Aires [that bore his last name]. Carlos arrived in Argentina at the age of 12. Silvestre, his father, and his older brother moved to Argentina one year before. Carlos married Josefina Ciarlo, & they had 10 children together. Their youngest daughter, Josefina, was my grandmother. Silvestre Zamboni passed away in Buenos Aires & is buried in this Recoleta vault. The stained glass above can be found inside & belongs to my family, descendants of Sylvestre Zamboni.
