Extractions: A Brief Note on Examples in London, Moscow, and Oxford by William Barker [December 2002] A L C I A T O H O M E P A G E The album amicorum (book of friends, also German Stammbuch ) is a kind of autograph book collected by early modern students or scholars from Germany or the Low Countries, as they moved about from university to university. Most of the books are made of paper, though there are examples on vellum. A typical page will have a tag or set of verses in Latin or Greek (or, sometimes, Hebrew) at the top, and below, a formal greeting in Latin to the owner of the album. Perhaps as part of the greeting there will be a heraldic shield of the signator or a small picture, often emblematic in nature, and these are sometimes coloured. The work is occasionally of very high quality, and suggests the book must have been kept by the signator for a time in order to prepare the work. The albums begin to appear in the middle of the sixteenth century, perhaps originating in Wittenberg. Philipp Melanchthon, the reformer, has this to say about them: These little books certainly have their uses: above all they remind the owners of people, and at the same time bring to mind the wise teaching which has been inscribed in them, and they serve as a reminder to the younger students to be industrious in order that the professor may inscribe some kind and commendatory words on parting so that they may always prove themselves brave and virtuous during the remainder of their lives, inspired, even if only through the names of good men, to follow their example. At the same time the inscription itself teaches knowledge of the character of the contributor, and quite often significant passages from otherwise and unknown and little-read authors are found in albums. Finally, they record biographical details which would otherwise be forgotten. (trans M.A.E. Nickson

Extractions: Einen Würfel oder einen Tetraeder kann man sich noch ganz gut vorstellen, aber wie sieht ein Dodekaeder aus? Ein Dodekaeder wird von 12 Seitenflächen begrenzt, welche regelmäßige Fünfecke sind, sich ein Bild davon zu machen stellt schon höhere Ansprüche an das geometrische Vorstellungsvermögen. Es ist ratsam ein Modell vorzuführen. So wird es auch schon Abraham Gotthelf Kästner (1712-1800) gemacht haben, der in der zweiten Hälfte des 18. Jahrhunderts an der Universität Göttingen neben der Mathematik auch noch viele andere Gebiete von der Astronomie bis zur Literatur vertreten hat. Die ältesten Stücke in der Modellsammlung des Mathematischen Instituts stammen jedenfalls aus der Zeit Kästners, es sind Kartonmodelle von Polyedern, unter denen auch das Dodekaeder zu finden ist. Mit den Fortschritten in Naturwissenschaft und Technik wuchs der Bedarf an Demonstrationsmaterial im mathematischen Unterricht. Neue, aufregende Entdeckungen, wie etwa der Clebschen Diagonalfläche, zu der weiter unten einiges gesagt wird, weckten das Interesse für geometrische Modelle auch seitens der Forschung. Damit brach um die Mitte des 19. Jahrhunderts die Blütezeit der mathematischen Modellsammlungen an. Zum Aufbau dieser Sammlungen wurden an vielen Hochschulen Modellierkabinette eingerichtet, in denen zunächst die benötigten Modelle in Eigenarbeit hergestellt wurden, wozu neben mathematischen Kenntnissen auch erhebliches handwerkliches Geschick erforderlich war. Mit steigenden Ansprüchen an Ausführung und Anzahl der Modelle verlagerte sich die Herstellung auf gewerbliche Betriebe. In Ausstellungen, meistens anläßlich Mathematikerkongressen, wurden die Erzeugnisse präsentiert und neue Techniken vorgeführt.
