For those curious, see about the School of #Sagres (1443CE), when the #Portuguese established a school of navigators, anchoring their know-how and cementing the firm tradition of Portulanos, booklets with annotated maps and logs of voyages from pilots, by pilots, for pilots.

In #Shogun , #Anjin speaks fluent Portuguese, by trade. #Mariko speaks Pt and Latin due to her conversion by Jesuits.

Imagine their dialogues in Portuguese, peppered by Blackthorne cursing and muttering to himself. =)
