Đàng Trong
Maiorica initially stopped in Goa, then arrived in Macau, intending to proselytize in Japan. However, by 1619, Japan had begun persecuting Christians, so he went instead to Makassar and remained there for a year. Afterwards, he returned to Macau and traveled to Fai-Fo (present-day Hội An) in 1624 in the same boat as Alexandre de Rhodes, João Cabral, and two or three other Jesuits. Whereas de Rhodes studied Vietnamese under Francisco de Pina (1585–1625), Maiorica studied Vietnamese at the Jesuit residence in Nước Mặn (today An Nhơn District, Bình Định Province). He proselytized in Đàng Trong (Cochinchina) from 1628, when his superiors sent him back to Macau en route to a new assignment in Japan. He was again unable to make the journey, this time due to poor weather. In 1630, he traveled to Champa, where he was quickly imprisoned. After a Portuguese merchant ransomed him, Maiorica made his way to Cửa Hàn (Danang) via Cambodia.
