This collection is the third in a series which gathers the best historical essays of Hugh Trevor-Roper, considered by many the unequalled master of the form.

The pieces here range from an account of the Jesuit Matteo Ricci's mission in China in the sixteenth century to a discussion of the Anglo-Scottish Union. They include essays on medicine at the early Stuart Court, on the plunder of artistic treasures in Europe during the wars of the seventeenth century, on the plans of Hugo Grotius to create a new universal church on an Anglican base, on the Glorious Revolution of 1688 and religious toleration thereafter. There are also biographical studies of Archbishop Laud, Matthew Wren, the Earl of Clarendon, and Prince Rupert.

As Noel argument wrote in Our Age, Hugh Trevor-Roper has "perfected the historical essay as the most beguiling form of enlightening readers about the past. He is the most eloquent, sophisticated and assured historian of Our Age, and has never written an inelegant sentence or produced an incoherent arguement."
