Florence, Italy: Physical Geography of the Renaissance Cradle

Hydrology: The Arno — Blessing & Threat
- Length:** 241 km (150 mi) — **Tuscany's largest river**.
- Flow:** **Highly seasonal** — **flash floods (1966 catastrophe: 4,000 m³/s, 101 dead, art devastation)** → **low summer flow**.

Why Geography Mattered
- Defensible river crossing** → **Roman colony (Florentia, 59 BCE)**.
- Arno = power (mills), transport (wool, marble), waste removal**.
- Hills = marble (Seravezza), timber, water, retreat villas (Medici).**
- Central node** — **Via Cassia (Rome), Via Francigena (Canterbury), Apennine passes (Bologna, North)**.
Florence's **physical stage—river, hills, valley, climate—didn't just host the Renaissance; it choreographed it.**
