Today's frisan is different to the old language, since it develloped like other languages.
Here is a nice poem in the old language:

The most astonishing language in (German) Frisia, however, is the existence of 'Saterlandish':
Frisian (Friesisch):
West Frisian (Westfriesisch):
The largest area is occupied today by West Frisian, and above all west of Groningen, including the islands of Schiermonnikoog and Terschelling. This region is bounded by North Lower Saxon and by the Zuidersee.
City Frisian (Stadtfriesisch):
Since the 16th century, a mixed dialect of Frisian and Dutch has been spoken in spots in the Dutch regions. This is the so-called "City Frisian", e.g., in Leeuwarden, the central point of the Dutch province of Friesland, in Dokkum, Franeker, Harlingen, and Staveren.
East Frisian (Ostfriesisch):
It is spoken between the Lauwersee and the mouth of the Weser, but especially on the island of Wangeroog.
Saterlandish (Saterländisch):
Only Saterlandish, with its parishes of Ramsloh, Stücklingen, and Scharrel in the high moors of the interior of northern Lower Saxony betwen the lower Weser and Ems in the vicinity of Friesoythe, has been able to maintain its identity in the midst of Middle Low German.
North Frisian (Nordfriesisch):
North Frisian is spoken on the Hallig islands and the neighboring strip of mainland on the western coast of southern Jutland and Schleswig, with elements of Danish and Low German mixed in.
Helgoland Frisian (Helgoländer Friesisch):
Quite different from the other Frisian dialects is the one spoken on the island of Helgoland.
East Frisian tea: you are sooooo right!
