Errat for Sidoli (2004a)

Errata:

p. 5, n. 14 - The final dative article should begin with a Tau.

p. 10, References - Olaf Schimdt's thesis was submitted in 1943, not 1938 (the citations in the paper are also incorrect).

Addenda:

According to Eutocius, in his commentary to On the Sphere and Cylinder II,. Nicomedes used the term diastêma for the defining distance of his conchoid. This usage is clearly relevant to the current topic. It seems to lend support to an instrumental interpretation.
