History

Which consequence results when the mater of an astrolabe warps?

A)Inaccurate celestial altitude readings
B)Loss of Alidade's magnetic properties
C)Erosion of the rete’s markings
D)Shearing of the suspension ring

💡 Explanation

Incorrect altitude readings from a distorted horizon occur, because the stereographic projection relies on geometric accuracy governed by the mater. Therefore altitude errors arise, rather than rete damage or alidade effects which are separate mechanisms.
