The Q’s dangling tail is not a recent problem, but dates to the first page of the first substantial book printed using moveable type in Europe.

When the wind blows through the dunes around the Western Chinese city of Dunhuang – long a garrison town between the Gobi and Taklamakan Deserts – it is said to produce sounds similar to song. In 366, the itinerant monk Yuezun was wandering through the arid landscape when a fantastical sight appeared before him: a thousand buddhas, bathed in golden light. (Whether heat, exhaustion or the strange voice of the sands worked themselves on his imagination is anyone’s guess.) Awed by his vision, Yuezun took up hammer and chisel and carved a devotional space into a nearby cliff-face. It soon became a centre for religion and art: Dunhuang was situated at the confluence of two major Silk Road routes, and both departing and returning merchants made offerings. By the time the site fell into disuse in the 14th century, almost 500 temples had been carved from the cliff.

Sometimes, when we’re putting together an issue of the LRB, we use Lorem Ipsum, a chunk of phoney Latin dummy text that’s been used by printers and typesetters since the 16th century. We paste it into a layout so we can tell what a page will look like before the copy's ready. The practice is known as ‘greeking’ because the Latin’s so mixed up it’s all Greek. Only it isn't. The text itself has been designed not to communicate, to have the look of text but no meaning – but meaning bubbles up through it nonetheless. The 16th-century printer who came up with it got there by mangling Cicero’s ‘De finibus bonorum et malorum’, an exposition of Stoicism, Epicureanism and the Platonism of Antiochus of Ascalon. Though most of the metaphysical subtlety has been wrung out, sense hasn’t completely: the text is haunted, as Derrida might have put it, by the piece of writing it once was.
