Henricus Petrus or Sebastian Henric Petri are two of the names used for publications from a 16th century printer shop of Basel (Basilea in Latin), also called Officina Henricpetrina.
One of their better know works is in 1566 the second edition of both De revolutionibus orbium coelestium by Nicolaus Copernicus, which originally had been published in 1543 in Nuremberg by Johannes Petreius, and of Narratio Prima by Georg Joachim Rheticus, published in 1540 in Danzig by Franz Rhode.
