The hotel where I’m staying in Tucson is across the street from the Arizona History Museum where I saw this statue of Father Eusebio Kino, SJ. Father Kino (1645 – 1711) was an early explorer and missionizer in what is now Baja California and Arizona.
For some reason I was particularly struck by the astrolabe he carries in his left hand.
His 17th century GPS system: the astrolabe was a precursor to the sextant & allowed Fr Kino to figure out his latitude.
