Abstract
I should like to draw attention to a metrical phenomenon observable in the hexameters of Callimachus and propound a ‘law’ which so far as I know has not been remarked on before; the accompanying discussion involves some refinements to our understanding of the metrical effect of proclitics of general importance to Greek metrical studies. In analysing the data I have made use of some standard statistical methods which could in my view be used throughout the whole field of Greek metrical studies with great profit . The analysis also provides some detailed evidence useful for a comparison of Callimachus, Apollonius Rhodius, Theocritus, and Aratus, and the earlier writers by whom the Hellenistic poets were influenced
