Herman of Carinthia (1105/1110 – after 1154), also called Hermannus Dalmata, Hermannus Secundus, Herman Dalmatin, or Sclavus Dalmata, by his own words born in the "heart of Istria", was a philosopher, astronomer, astrologer, mathematician and translator of Arabic works into Latin.
Alongside Adelard of Bath, John of Seville, Gerard of Cremona and Plato of Tivoli, Herman is the most important translator of Arabic astronomical works in 12th century. The influence of his translations on the development of medieval European astronomy was especially large.
