31 ?Flemish ASTROLABE post 1582
Not signed or dated. Brass. Diam.;281mm.
Ret for 48 stars. THe pattern of the tracery of the rrete is similar to that found
on astrolabes from the Arsenius workshop in Louvain (cf.astrolabe no.28).
3 plates, for latitudes 42°, 43°, 44°, 45°, 46° and 48°, engraved with almu-
cantars for every degree. The mater is engraved with a quadratum nauticum.
The back of the instrument is engraved with the usual zodiac/calendar scale(0^o Aries =
21 March [i.e. Gregorian]; concentric type), and with a shadow-square; There is
also a scale for the conversion of equal and unequal hours. Details of the engraving
suggest that this instrument may be quite recent.

family of Lucca.
