Refined criteria Archimedean sources of the whole extant tradition suited to establish a chronological ordering of the on the balance; Archimedean works have been proposed by Wilbur R.

The criteria are: the evidence about an Archimedean Catoptrics. The form of exhaustion procedure employed: The The Archimedean Palimpsest. This is the main criterion.

The Arabic fragment simply gives the values of the areas In Method 14, a passage unread by Heiberg, within a of the fourteen parts as fractions of the area of the whole column of text that requires extensive restoration, reveals square. Such areas turn out to be unit fractions of the that Archimedes handles infinite multitudes of mathemat- whole; the only exception, the area of HEFLT, is written ical entities by setting them in one-to-one correspon- as a sum of unit fractions.

The Greek fragment amounts dence. One should not attach too much importance to to a short, initial introduction and to a partial con- this move as if it was an anticipation of modern set-theo- struction of the diagram the one implied by the Greek retic treatment of infinities.

The move adds nothing to the text actually makes AZEB a square. The aim, Pappus, Collectio IV. A Archimedes asserts that new edition of the Arabic treatise makes it possible to there is not a small multitude of figures made of write in a correct form some passages in the construction them, because of it being possible to take them of the regular heptagon ascribed to Archimedes. K It may be added that the neusis involved in the con- Q struction of the heptagon can be solved in a straightfor- ward way by a simple adaptation of the solution of the neusis reported in Pappus, Collectio IV.

The proof, if framed in analogy with Pappus, that the con- struction really solves the neusis is considerably simpler Figure 1. D Simplified variants of the same theorem as in Almagest I.

Two the Greek mathematical corpus, it is likely that the tangents AB and AG are drawn to the same circle, and the approximations at issue were obtained in that way. From point D on that line another tangent is drawn, touching the circle at Z and intersecting the other two tangents at E and H.

D The easy proof draws the parallel ET to AB and argues by similar triangles and from the equality of tangents to a cir- cle drawn from the same point. H G One interesting feature is that the lemma holds also when the two initial tangents are parallel: In this case the text displays two letters A denoting different points. The E fact that Apollonius proposed similar theorems for conic sections in Conics III might be taken as supporting the Z Archimedean origin of lemma 12, because Apollonius shaped his Conics as a system of scholarly references to preceding authors.
