Hermann of Carinthia: The Search of the Heart
“Every question of astronomy… is either in thought or in speech.”
In the 1140s AD, Hermann of Carinthia assembled instructions from medieval Arabic-speaking authorities on interpreting the unstated thoughts of clients (now called “consultation charts”), often using a “victor” or mubtazz or almuten for topics or the chart. Hermann also offered his own reflections on the proper balancing of dignities, house rank, and planetary strength.

Bishr, Abu Ma’shar, ‘Umar al-Tabari, ‘Ali al-‘Imrani, al-Kindi, and others.
