Vitello's treatise in optics was closely linked to the Latin version of Ibn al-Haytham's Arabic opus: Kitab al-Manazir (The Book of Optics; De aspectibus or Perspectivae), and both were printed in the Friedrich Risner edition Opticae thesaurus (Basel, 1572).
[4] Vitello's Perspectiva, which rested on Ibn al-Haytham's research in optics, influenced also the Renaissance theories of perspective.
Lorenzo Ghiberti's Commentario terzo (Third Commentary) was based on an Italian translation of Vitello's Latin Perspectiva.
[5] Vitello's treatise also contains much material in psychology, outlining views that are close to modern notions on the association of ideas and on the subconscious.
Vitello argues that there are intellectual and corporeal bodies, connected by causality (corresponding to the Idealist doctrine of the universal and the actual), emanating from God in the form of Divine Light.
