Horae Terrenae — The Earthly Book of Hours — is a daily primer of literature, art, and ecology: a portiforium poeticum or perhaps a modernist breviary for encountering the day (or night) and yourself in it. It's a collection of texts, images, and phenomena for observing biological and cultural rhythms, seeing inside or under or through or beyond. Use it to navigate the nychthemeron and chart your diel cycles.
Horae Terrenae — The Earthly Book of Hours — is a meditation on time, nature, and the cyclical patterns that structure our days. It maps the 24 hours of the day to eight poetic "blocks," each associated with a particular quality of light, a cast of natural phenomena, and a collection of readings from literature, philosophy, and natural history.
The project draws inspiration from Books of Hours, the illuminated manuscripts of medieval Europe that organized daily prayer around the canonical hours. But instead of prayer, this version asks: what if we collected poems, quotes, and observations of the natural world and arranged them according to the hour of day? What patterns would emerge?
Each block — from Void (midnight) through Denouement (night) — contains:
• A poetic statement (versicle)
• A curated selection of literary quotes
• A list of natural phenomena occurring at that hour
• An image or artwork that captures the spirit of the time
When you visit, the site displays content from the current hour. As the day changes around you, so does the content — a gentle reminder that time is always moving, and that each hour has its own particular character.
The Reading page provides a full list of all sources consulted in creating the hours — literature, natural history, philosophy — along with links to freely available texts and recommended editions.
Horae Terrenae is an ongoing project. If you have suggestions for quotes, images, or natural phenomena to include, or if you'd like to follow along as the hours grow and deepen, subscribe to Lectio Terra on Substack.
