We always live in the last moment of history. No one has ever come any further in time. All ages shape their own apocalyptic vision, a way of understanding the perils and revelations that perennially surround us. Endtimes explores such visions over the last two thousand years, since John of Patmos first looked out of his window and saw FINIS written in vapour trails on the blue Aegean sky. From Roman tyrants to the persecuted Russian poet Osip Mandelstam, this sequence explores the dark side of our history, and the glories such darkness continues to provoke in our art and literature.

One of five chapbooks published by Shearsman in the summer of 2012, Alan Wall's Raven is a single long poem-sequence.

Doctor Placebo finds himself at the end of the western intellectual tradition, and on certain mornings feels almost as old. As a medical practitioner he broods about his patients; as a writer he broods about his poems. Sometimes the two intermingle and he can't remember whether he is a doctor moonlighting as a poet, or a poet moonlighting as a doctor. One thing at least remains constant: moonlight. The end of the western intellectual tradition, like Placebo himself, is insomniac.

This volume features two long pieces: the title work - a translation & partial transposition of the Gilgamesh epic - and the mixed work in verse and prose, Jacob, originally published in the 1990s and long unavailable. In both works history, myth and the present collide. Jacob was shortlisted for the Hawthornden Prize when first published.

Accompanying Alan Wall's Gilgamesh is his new collection of shorter poems and sequences, the centrepiece of which is the London section, in which the author inhabits the clothes of a number of old masters who have lived in London or its environs: Alexander Pope, of course, but also Thomas More, Johnson, Coleridge, Keats, Burton, Rosenberg, Pound and others. Then, 'Lenses' deals with Alexander Topcliffe, an early astronomer, and the unlucky Marsyas also makes an appearance: the cast of characters is extensive, and each is presented with the skill of a novelist, mixed with the precision of the poet.

When Christopher Bayliss abandons Rome, he returns to England determin ed to be cleansed forever of the contagion of religion. He says that he is more than happy to leave behind his angels along with his demons . But his research into an obscure 18th century poet, Richard Pelham, reintroduces into his life those same ghostly whispers and rumours he thought he'd silenced for good. And so he flees once more, into a dif ferent type of life entirely - he escapes into worldly success. But he cannot escape Richard Pelham's demons. Soon they take over his life. Then finds himself cloistered again, this time in the Richmond booksh op of Stamford Tewk, whose archive is said to contain crucial unpublis hed material regarding the life and work of Pelham. Tewk himself is a legend in the world of writing and scholarship. Age has in no way dim inished the astringency of his intellect or the savagery of his tongue . Christopher comes to see that what Tewk is offering to sell him wil l be costly, but only gradually does he understand quite how great a p rice he is being asked to pay.
