In insula est columella, in qua intus axis, qui pro mensa sustinet rotam radiatam, ita ut ad extremum, ubi orbile solet esse, arcuata tabula cavata sit ut tympanum in latitudinem duo pedes et semipedem, in altitudinem palmum.
On the island is a small column, and on the inside of it is a post, which holds up, instead of a table, a wheel with spokes, in such fashion that on the outer rim, where the felloe usually stands, there is a curved board with raised edges like a tambourine, two and a half feet in width and a palm in height.
