Foundations
Before instruments, forecasts, and equations, weather was understood through observation, philosophy, and experience. People watched the sky, tracked seasons, named winds, and tried to explain why rain fell or drought persisted. These early efforts were not meteorology as we know it today, but they form the foundation on which later scientific approaches were built.
This section explores the earliest ways humans attempted to understand atmospheric phenomena. It includes philosophical texts, cultural frameworks, and physical artifacts that shaped how weather was observed and interpreted long before standardized measurement or formal forecasting existed.
What “Foundations” Means Here
Meteorology did not begin as a single discipline. In antiquity and the early historical period, ideas about weather were closely tied to natural philosophy, medicine, agriculture, navigation, and cosmology.
In this section, “Foundations” refers to:
-
Early attempts to explain weather and atmospheric phenomena
-
Systematic observation without instruments
-
Conceptual frameworks that influenced later scientific thought
-
Public and cultural representations of weather knowledge
These materials are presented in their historical context, without judging them by modern standards.
Time Period Covered
Broadly, this section spans:
-
Antiquity
-
The classical Greek and Roman world
-
Late antiquity and early transitions toward measurement
Later developments involving instruments, networks, and formal forecasting are covered elsewhere in the archive.
What You’ll Find in This Section
-
Early philosophical texts that attempted to explain weather as part of the natural world
-
Descriptions of winds, precipitation, and atmospheric phenomena based on observation
-
Monuments and artifacts that reflect public or civic engagement with weather
-
Conceptual models that shaped meteorological thinking for centuries
Some entries focus on texts, others on objects or ideas. Together, they show how weather knowledge began to move from myth and omen toward explanation and classification.
c. 800–400 BCE
Atmosphere and Cosmic Cycles in the Upanishads
An early exploration of atmospheric processes within a cosmological framework. The Upanishads, composed between the 8th and 4th centuries BCE, describe the movement of water, rainfall, and the atmosphere as part of a unified system of natural and cosmic cycles.

c. 600–400 BCE
Presocratic Cosmology and Early Weather Thought
An early phase in the development of natural explanations for weather. Presocratic philosophers of the 6th and 5th centuries BCE proposed cosmological ideas about air, water, and elemental change that later influenced Aristotle’s systematic account of atmospheric phenomena.
c. 5th century BCE
Hippocrates’
Airs, Waters, and Places
One of the earliest surviving works to link environment and human health as a coherent subject of study. Written in the late 5th century BCE, it offers a window into how climate, water, winds, and geography were understood to shape the body and patterns of disease in early Greek medicine.

How This Section Connects to the Archive
The ideas explored in Foundations directly inform later developments in:
-
Instruments & Observation, where weather became measurable
-
Forecasting & Theory, where explanation gave way to prediction
-
Institutions & Networks, where knowledge was standardized and shared

A Note on Sources and Interpretation
Early weather knowledge often blends observation, philosophy, and belief. Where possible, original texts and artifacts are discussed alongside modern historical analysis to clarify what was known, what was assumed, and what questions remained unanswered.
