Note 638 — INDIGO.

Salmasius in Homonymis Hyl. Iatr. p. 177, a; and in Exercitat. Plin. p. 810, b; and p. 936, b. In regard to the manuscripts of the work of Zosimus, which is commonly called Panopolita, see Fabricii Bibl. Græca, vol. vi. pp. 612, 613; and vol. xii. pp. 748, 761. I wish I may be so fortunate as to outlive the publication of it; it will certainly throw much light on the history of the arts. It is remarkable that Zosimus calls indigo-dyers λαχωταὶ and ἰνδικοβάφοι, in order perhaps to distinguish them from the dyers with woad. The distinction therefore between indigo-dyers and those who dyed with woad must be very old.
