(1937), to refer to an impressive speech at the conference. Justine's major work is the book Dante’s veelzijdigheid about the interpretation of the conceptions mentioned in the works of Dante, a sort of literary lexicon. It mainly regards the conceptions in the 14th century epic poem The divine Comedy. This book was published in 1929 by Van Stockum in The Hague. Its Italian translation Il sapere universale di Dante came out a year later, published by the Florence publishing house Tipografia Sordomuti. The title page contains lines from 'The Inferno' section' of The divine Comedy, which Justine altered in her address to the great poet (these are also in the text of her ex-libris): Dante, Vagliami 'l lungo studio e 'l grande amore / Che m’ha fatto cercar lo tuo volume (Inf. I: 83, 84) (in the style of Justine’s Dutch translation: Dante, / That thou mayest reward my long study and the great love / That made me search for thy work) Both editions include her own poem in praise of Dante. Of course she also made a translation for the Italian reader. Justine's epilogue of the Dutch edition as well as her preface to the Italian edition is dated at Easter. This date is symbolic: At Easter Day Dante returned from his journey through the hereafter, similar to the resurrection of Jesus Christ. In her personal copy, she registered that the Dutch edition came out on the first of July 1929: her son's wedding day.

In an early stage Justine realized that Dante had put the whole knowledge of his time in his works. Analyzing the oeuvre with emphasis on The divine Comedy, she divided the rich information into the categories 'enkelvoudige dingen' ('singular subjects') and 'samengestelde dingen' ('combined subjects'), which she in Dante’s veelzijdigheid and its Italian version consequently divided. In the first category one finds the subcategory 'the four elements'. In the second category the subcategories: 'minerals', 'plants', 'animals' and 'human beings'. In turn all subcategories were further divided by Justine. Dante himself in his work Il Convito (The Banquet), hands over the categories and subcategories to his readers. Justine's alphabetical index shows par excellence the 'veelzijdigheid' (diversity) of the erudite poet: one reads words from horse riding to monkey, from drums to
