A while ago I ran into this book in an antiquarian bookshop on one of the Dutch islands. It costed only 4 euros. I knew about this publication, the local library has/had two of these, one with translated letters, one with essays. The special thing about these translations is that they are hand written. I have not been able to find out in what year these books were published, but many years later, the Rosicrucian society Lectorium Rosicricianum published a little book also hand written by ‘members of the school of philosophy of Amsterdam’. The book contains Ficino’s five keys to Platonic wisdom and the ‘introduction to the Platonic theology’, quite like the 2005 Dutch translation published by the same publisher as the little commemoration book, but the translations differ obviously. The handwriting is done by different people. This is not visible in the written characters, but it is in line-endings. One writer managed to create filled-out lines, while another writer’s right side of the text is more wobbly. The publication is beautiful and the translations inspiring. When you can read Dutch and wanted to read something of Ficino anyway, I suggest you try to find one of these beautiful books. They are not too hard to find nowadays it seems. Somehow it is often listed as “uit het brievenboek van Marsilio Ficino” (“from the letterbook of Marsilio Ficino”). I do not know where that title comes from, but perhaps it has something to do with the other book with letters. Strangely enough it seems that there are no English translation of Ficino’s five keys and introduction, while there are complete translations of Ficino’s Platonic works and several other publications.
