Victor Hugo wrote The Hunchback of Notre-Dame under enormous financial pressure, leaving his table only to eat or sleep.

Finally, his daughter Adèle wrote, “On 14 January, [Notre-Dame] was finished. The bottle of ink that M. Victor Hugo had bought the first day was finished also; he had arrived in the same moment at the last line and at the last drop.

“This gave him, in that moment, the idea of changing his title and calling his novel: What There Is in a Bottle of Ink.”
