It was called the Royal Bible because it was sponsored by King Philip, and the Antwerp Polyglot because it was printed in the city of Antwerp, which at the time was a part of the Spanish Empire.
Par Biblia regia (karalisko Bībeli) šo Bībeles izdevumu nosauca tāpēc, ka to atbalstīja un finansēja karalis Filips, bet par Antverpenes poliglotu — tāpēc, ka to izdeva Antverpenes pilsētā, kas tolaik ietilpa Spānijas impērijā.
