Stadia (length)
From Wikipedia, the free encyclopedia
For the land surveyor's device, see Stadia rod.
The stadia, stadium, stade or stadion is an ancient unit of length. According to Herodotus, one stade is equal to 600 feet. However, there were several different lengths of “feet”, depending on the country of origin.
| Stade name | Length (approximate) | Description |
|---|---|---|
| Itinerary | 157 m | used in measuring the distance of a journey.[1] |
| Olympic | 176 m | 600 × 294 mm |
| Attic/Italic | 185 m | 600 × 308 mm |
| Babylonian-Persian | 196 m | 600 × 327 mm |
| Phoenician-Egyptian | 209 m | 600 × 349 mm |
Which measure of the stadia is used can affect the interpretation of ancient texts. For example, the error in the calculation of the size of the Earth by Eratosthenes is dependent on which stade is chosen to be appropriate.[2]
