Dominicus Gundissalinus or Gundisalvi was a translator and philosopher who worked in Toledo (Spain) during the second half of the 12th century. He has been the Latin initiator of crucial tendencies that would mark much of the later medieval discussion in ontology and natural philosophy.

– universal hylomorphism
– plurality of substantial forms
– hylomorphism as the ontological correspondent to possible existence
– rejection of the theory of primordial chaos
