Utriusque Frisorium. That the Frisians are a very ancient people, living at the mouth of the Rhine near the Ocean, where they still live today, is very clear from the ancient writers. For Ptolem�us describes those who live above the Busactores, between the river Eems and the Vidrum {1598D{also called Swarte-water <= black water>}1598D}. Tacitus, who attributes to them a prominent reputation among the Dutch {not in 1598F{and near the sea where the Rhine empties into it}not in 1598F}, divides the Frisians into the Greater and the Lesser, according to their power and governance, saying that their area covers the great Lakes on which the Romans have navigated.” from text on back of map translated by Marcel van den Broecke”
