In like sorte that roote is called a Squared square roote, whiche maketh a square of squares in nōber. A sursolide roote. And that roote is a Sursolide roote, that yeldeth a Sursolide nomber: in whiche sorte of multiplication, you maie procede infinitely, as I saied.

Notwithstandyng for your ease, I haue set foorthe here in a table, certain of the moste notable kindes of rooted nombers.

And to the intente you maie partly conceiue the reason of their names, I will after the table, set forth a brief explication of their names, with the protracture of the figures, that thei doe resemble in multiplications Geometricalle: where poinctes, lines, platte formes, or sound formes bee multiplied: and brynge foorthe other formes agreable to soche multiplications.

But first marke the table well: And it will giue you greate lighte, and aptnesse to vnderstande all that foloweth, moche the better.

For examples are the lighte of teachyng.The
