thunder, from dream explanation to vocation muses. The Dutch artist Jan Toorop (1858–1928) made the watercolour entitled 'Dante verheft de Ziel' (Dante lifts the soul) especially for Justine. The painting depicts Justine kneeling before Dante in divine admiration, with The divine Comedy under her arm. She used it for the cover of the Dutch edition of her book. The Dante portrait by Giotto (c. 1267–1337) she used to illustrate the interior of her Italian edition. In Italy, 1965, Justine's interpretation on the fall of Lucifer in the 'Inferno' section, published in De nieuwe Gids – most probably her first in print – was noticed at the preparation of Dante's 700th birthday. The author of Dante e la medicina, a book presumably published because of this commemoration had consulted the 'lexicon'. Justine's reference book Dante’s veelzijdigheid and its translation Il sapere universale di Dante still is a useful tool for Dante study. It nowadays offers an entry – also thanks to the headwords in page margins and index – to the difficult Divine Comedy. The masterpiece of world literature remains, even after years of study and dedication, in essence utterly incomprehensible as we can read in Justine's laudatory poem on Dante: Bibliography 'Iets over 'la Tomba' di Lucifero ed il 'Cammino Ascoso'’, in: De nieuwe Gids XXVI (1911) (July) p. 69-78 Dante’s veelzijdigheid (The Hague 1929) (incl. laudatory poem) Il sapere universale di Dante (Florence 1930) (same book, translated by the author) (incl.
