“…The case for reading this Propertian nexus in the Empedoclean mode has been made for elegy 4.4, where inflections of Virgilian figures of Strife map Tarpeia's oscillation between love and war onto an Empedoclean framework that arguably promotes a view of the poem's violence as politically productive. 48 As the predicament of an elegiac lover, Tarpeia's conflict between Love and Strife is analogous to that witnessed in Tibullus above, and shows thereby the extent to which the elegiac scenario in general may be susceptible to Empedoclean interpretation. It is perhaps significant that, like Tibullus 2.5, this elegy and Propertius 4 as a whole are conversant with Virgilian epic and with Aeneid 8 in particular.…”

“…3 [35][37][38][39][40][41][42][43][44][45][46][47][48][49][50] where, stranded mid-campaign due to illness, he contrasts the glorious reign of Saturn, 'before the earth was opened out for distant travel'(35-6 priusquam | tellus in longas est patefacta uias), with the Jovian age of the present (49-50 nunc Ioue sub domino caedes et uulnera semper, | nunc mare, nunc leti mille repente uiae, 'But now that Jupiter is lord, there are wounds and carnage without cease; now the sea slays, and there are a thousand ways of sudden death'). Lucretius, in the proem to the De rerum natura, similarly writes from a notional 'iron age' of strife (it is perhaps not 'casual'38 that he addresses Memmius at DRN 5.1282, the point at which he turns to the discovery of iron in his rationalized account of the Myth of Ages).…”

Initial research for this paper was conducted during tenure of a British Academy Postdoctoral Fellowship at the University of Oxford. I am grateful also to audiences in Dublin, Glasgow, Manchester, and Seattle for helpful response to earlier versions; also to A. Hardie, S. Trépanier and C. Ware for valuable discussion and feedback; and to Dictynna's anonymous reviewers for robust and insightful criticism.

Premature black hole death of Population III stars by dark matter

Population III stars were the first generation of stars, formed in minihalos of roughly primordial element abundances, and therefore metal-free. They are thought to have formed at the cores of dense dark matter clouds. Interactions between baryons and dark matter can therefore have had an important impact on their evolution. In this paper we consider the capture of non- or weakly-annihilating dark matter by these early massive stars. In a wide region of parameter space, interactions of dark matter with baryons lead to premature death of the star as a black hole. We sketch how this modification of the standard evolutionary history of Population III stars might impact the epoch of reionisation, by modifying the amount of UV emission, the transition to Population II star formation, and the X-ray and radio emission from accretion onto the black hole remnants. Signals of massive black holes originating from Population III stars could be observed through gravitational waves from their mergers. Finally, the observation of pair-instability supernovae could effectively preclude premature black hole death across a wide range of parameter space, ranging in mass from m DM ∼ 0.1 GeV to m DM ∼ m Pl.
