Observation is devotion · The astrolabe, unani tibb

Rootsthe tradition
The planispheric astrolabe with its pierced rete and stacked latitude plates, the mizan of unani tibb, pulse-reading, star tables, the qibla dial.
The ideawhat it values
Instruments were built to be handled rather than admired: a plate of brass engraved with the sky as it stands over a given latitude, turned until it agrees with the night. Medicine proceeded the same way, by temperament and balance, patient by patient. Neither field drew a line between what was measured and what was owed.
