A Handbook for life
Meditations (Classics)Meditations (Classics) by Emperor of Rome Marcus Aurelius

As above, but I slightly prefer Aurelius' work - His position as Emperor makes it more interesting
The Twelve Caesars (Penguin Classics)The Twelve Caesars (Penguin Classics) by Suetonius
Buy new: £32.51 / Used from: £4.90
Although still a great biographer (not as good as Plutarch though), Suetonius' '12 Caesars' is a great read precisely because it offers an insight into the personal lives of the Emperors
The Iliad (Oxford World's Classics)The Iliad (Oxford World's Classics) by Homer
Buy new: £3.46 / Used from: £0.04
The greatest work of Classical Literature in existence, if you haven't read this, then there is something wrong with you
History of the Peloponnesian War (Classics)History of the Peloponnesian War (Classics) by Thucydides
Buy new: £6.99 / Used from: £1.20
No offence meant to Herodotus, but Thucydides' was the real father of History, the narration of Pericles funeral speech is beautiful

Perhaps the most seminal work of Philosophy and Political Science in History
