A great scientist and a great philosopher in a 12th century, Croatian Herman Dalmatin was one of the most prominent people in his time. Herman known as Herman of Carinthia was Istrian philosopher, astronomer, astrologer, mathematician, translator and author first went to a Benedictine monastic school in Istria. Later after finishing schools in France he decided to travel across Europe and the Middle East while profiling himself as a respected translator. Most of the works he translated were about astrology and the occult since that were the topics that gained his interest. Dalmatin was so deeply enchanted by these subjects that he even wrote some books about it by himself, such as „De indagatione cordis” and „De occultis”. The crown of his work was the translation of the Kur’an on Latin which played a big role in presenting Islam to the Christian Europe. After the publishing of the translation, very little information is found on further events in his life but it is known that he inspired numerous scholars and philosophers centuries after his death in 1142.
