History
Origin
The watermarks, all coherent with a date around 1500-1510,
corroborates the dating by the note 1505 on f.
47v
, 1506 on f.
71v
and
72r
, and the birth of someone in 1477 indicated by the
horoscope on f.
26r
. The note on f.
64v
in German Tauel dex Sunnen hoch im mittag auff eyn yeder
grad dex 12 zaithen auff Nurnberg do dex polus ist 49 grad
30 mto together with a note on f.
49v
which specifies that the tables are adapted for a
latidudinal position of 48 degrees, suggests that the
manuscript was executed in e.g. Munich or Vienna and later
transferred to Nuremberg.
