In the last volume of this Annual (xxiii. 206 ff.) I attempted to restate the arguments for the view that the provincial era of Macedonia dates from 1st Dios, 148 B.C., and the Actian (or, to give it the name which it bore in Macedonia, the Augustan) era from 1st Dios, 32 B.C.
I mentioned (p. 210) Prof. M. Holleaux as having expressed in 1914 a doubt of the continued existence of separate Macedonian and Achaean eras running concurrently and a desire for further investigation of the question. This was, indeed, the starting-point of my own inquiry. I regret, however, that I overlooked a later statement of the same scholar (Rev. Et. Anc. xix. 81), who in 1917 accepted as fully established the Macedonian era of 148 B.C., and pointed out that the Oxyrhynchus Epitome of Livy proves that the defeat of Andriscus and the submission of Macedonia took place in that year (cf. Kornemann, Die neue Livius-Epitome aus Oxyrhynchus, 91 f., 113 f.). Further, in an article which became accessible to me only after my own discussion was already in print, Pomtow himself has declared in favour of the earlier starting-point of the Macedonian era, on the ground both of the Macedonian and also of the Delphian documents.
