The Medieval Moon – Book of the Week

Published by Yale University Press in 2025, The Medieval Moon: A History of Haunting and Blessing ranges across nine centuries — from c.700 to 1600 CE — and across a strikingly wide global field, from China to South America, Korea to Wales, and beyond. Lazikani reveals that for many cultures, the moon was more than a mere celestial body: it could evoke love, beauty, and gentleness, but also pain, hatred, and violence.

The book draws on Old English riddles, Sufi love poetry, Mayan/K’iche’ tradition, Inca cosmology, Old Norse mythology, Islamic medicine, Christian symbolism, and medieval medical theory, tracing how a single shared object overhead generated such wildly different — and sometimes contradictory — meanings. It is rigorously researched and richly illustrated, but the writing stays accessible throughout.

Who it’s for

This is ideal reading for anyone drawn to cultural history, the history of science and religion, medieval literature, or the Global Middle Ages — though readers expecting a straightforward chronological narrative or a deep focus on any single region may find the book’s wide, survey-style sweep requires patience.

A Behind-the-Scenes Gem

One of the book’s more quietly striking details is the way Lazikani handles the moon’s changing form. In its full, round shape, the moon could be linked to fertility, fullness, and abundance. Yet in its crescent and other shifting forms, it could seem broken, even wounded.

This contradiction — the same object blessing and cursing, healing and threatening — threads through the entire book, and it is what elevates the study above a catalogue of lunar folklore. Lazikani uses the moon’s changing shape as a way into the emotional life of medieval cosmology: how the same sky could look entirely different depending on where you stood, what you believed, and what you feared.

A sharper example comes from Christian theological and political symbolism. Bernard of Clairvaux could understand the moon as a metaphor for the Church, its changing light dependent on a higher source. Pope Innocent III, however, turned the same cosmology into a political weapon: the pope became the sun, while the Holy Roman Emperor was cast as the subordinate moon, reflecting papal authority. Two men, one sky, and centuries of power politics compressed into a celestial metaphor.

Verdict

The Medieval Moon belongs to a growing and welcome genre of thematic medieval history — books that use a single object, material, or idea to open out an entire world. Lazikani’s approach is what she calls a “multi-glance” method, a cross-cultural way of looking from one lunar tradition to another without reducing them to a single story.

From the belief that the Black Death was caused by a lunar eclipse together with a planetary conjunction to the wealth of Persian and Andalusian love poetry inspired by the moon’s beauty, this is a truly wide-ranging account of our closest celestial neighbour. That global span is the book’s great strength, and for readers of this site who already follow the Islamic world alongside the Latin West, it feels long overdue.

There are moments when the breadth comes at a cost. Readers who want sustained depth on, say, Arabic astronomical theory, Islamic medicine, or Inca lunar traditions will want to seek out specialist works alongside this one. But as a panoramic introduction — beautifully produced, source-led, and free of jargon — it does exactly what the best popular medieval history should do: it makes you feel the strangeness and intelligence of the past without talking down to it.

Ayoush Lazikani writes with the kind of precision that comes from deep scholarly training and the kind of warmth that makes you want to read on. The standout reason to pick this up is simple: it takes a subject that seems universal and shows you just how much the medieval world disagreed about it. The moon they saw was not your moon, and that gap is fascinating.
