Astrolabe plate for 27º, engraved in two different hands, only 7.5cm diameter.

A very elegant single astrolabe plate, 18th century, from an Indo-Persian astrolabe, possibly made at Lahore. Engraved on both sides for 27º, but by two distinct makers. Projection lines are dotted and solid and are now quite faint, but the script is very clear and finely engraved. Similar in style and size to the two plates that were presented to the History of Science Museum, Oxford, in 1955 (inv. nos 41524 & 88453). Housed in a custom-made clamshell box.
