Medieval European · 1261–1264 CE
Theorica planetarum
Describes the Ptolemaic planetary models with full dimensions and gives the first European description of an equatorium, 'basically a mechanical calculator to give the planetary motions', which Campanus probably never built. MacTutor, discussing his astronomical tables, says Campanus 'determined the time of each planet's retrograde motion'; whether that refers to this work or to separate tables is unresolved.
