Heliodori carmina quattuor - Heliodorus, Emesenus sec. III/IV (A. Töpelmann, 1923)
Four Greek poems on alchemy, purporting to have been composed by the philosophers Heliodorus, Theophrastus, Hierotheus and Archelaus, respectively, but evidently the works of one and the same author, the alchemist Heliodorus of the 8th cent. Cf. Praefatio.
