Pascalis Romanus (or Paschal the Roman) was a 12th-century priest, medical expert, and dream theorist, noted especially for his Latin translations of Greek texts on theology, oneirocritics, and related subjects.
While the Liber thesauri occulti draws on the tradition of humors, Pascalis goes beyond the connection Macrobius makes between insomnium and hunger or thirst to offer an elaborate psychosomatics.
Where Macrobius had explained the visum in terms of an incubus,[6] Pascalis offers a complex medical explanation involving blood circulation, the bodily position of the sleeper, and humoral disposition.
In his preface, he summarized his method: I have striven faithfully to make [my translation] as good as the Greek book throughout, by picking up not the words, which are [in themselves] of a barbarous sterility, but rather the sense, which is useful.
[8]Other Latin translations from Greek by Pascalis include the Ystoria Beate Virginis Marie by the 8th–9th-century priest and monk Epiphanios and the Disputatio contra Judaeos attributed (with difficulties of chronology) to Anastasios of Sinai.
