shows at this part of the picture the choice of a Virgo-presentation, which is also remarkable in Lorenzo Spirito's lot book version (he uses the Virgo-symbol twice, likely one picture defining as "before wedding" and the other "after wedding") ... this picture shows left the unicorn as sign of virginity and likely as contrast at the right a female with stag. In the lot book of 1520 the sign Capricorn uses the unicorn (Nr. 13) and Nr. 19 (likely indicating "moon") uses the stag.

The picture shows according description an astrolabium and in the mid an added wheel of paper, which can be turned ...
... such implemented wheels are common for lot books and the horn of the unicorn is occasionally used as pointer. In this book, however, it seems to have astrological function.
It contains partly articles of Johannes Hartlieb, who lived till 1468 (likely) in Augsburg and might have been acquainted to Bollstetter. This text ...

*****************************Johannes Hartlieb (ca. 1410 – 18 May 1468) was a physician of Late Medieval Bavaria, probably of a family from Neuburg an der Donau. He was in the employment of Louis VII of Bavaria and Albert VI of Austria in the 1430s, and of Albert III of Bavaria from 1440, and of the latter's son Sigismund from 1456. In 1444, he married Sibilla, possibly the daughter of Albert and Agnes Bernauer Hartlieb wrote a compendium on herbs in ca. 1440, and in 1456 the puch aller verpoten kunst, ungelaubens und der zaubrey (book on all forbidden arts, superstition and sorcery) on the artes magicae, containing the oldest known description of witches' flying ointment. Hartlieb also produced German translations of various classical authors (Trotula, Macrobius, Gilbertinus, Muscio).
The book has a lot of nice pictures ... for instance 36 star constellations according Michael Scotus (interesting especially cause the use of name-variations). The picture shows Hydra with a Raven, the constellation, which was as 13th month in the Bollstetter-Losbuch. Also 360 paintings for each degree of the circle according Peter of Abano with 36 pictures for each decanat.
