In 1585 Lord Deputy Sir John Perrot undertook the shiring of Ulster (excluding the counties Antrim and Down, which had already taken shape); and his work, though of little immediate effect owing to the rising of Hugh O'Neill, served as a basis for the division of the territory at the plantation of Ulster in the reign of James I.
Fermanagh was formed into a county on the shiring of Ulster in 1585 by Sir John Perrot, and was included in the well-known scheme of colonization of James I., the Plantation of Ulster.
He served with the English against Desmond in Munster in 1580, and assisted Sir John Perrot against the Scots of Ulster in 1584.
In the following year the Franciscan friar Father Louis Hennepin, acting as an agent of the Sieur de la 'Salle, discovered and named the Falls of St Anthony; and in 1686 Nicholas Perrot, the commandant of the west, built Fort St Antoine on the east bank of Lake Pepin, in what is now Pepin county, Wisconsin, and in 1688 formally took possession of the region in the name of the French king.
Since all the Syrian monuments of the Hittite class, so far known, seem comparatively late (most show such strong Assyrian influence that they must fall after 110o B.C. and probably even considerably later), while the North Cappadocian monuments (as Sayce, Ramsay, Perrot and others saw long ago) are the earlier in style, we are bound to ascribe the origin of the civilization which they represent to the Cappadocian Hatti.
