Campanus of Novara (c. 1220 – 1296) was an Italian mathematician, astronomer, astrologer, and physician[1] who is best known for his work on Euclid's Elements.[2][3] In his writings he refers to himself as Campanus Nouariensis; contemporary documents refer to him as Magister Campanus; and the full style of his name is Magister Campanus Nouariensis.[2] He is also referred to as Campano da Novara, Giovanni Campano or similar. Later authors (from the 16th century on) sometimes applied the forename Johannes Campanus or Iohannes Campanus.[1][2][4]

His date of birth is uncertain but may have been as early as the first decade of the 13th century and the place of birth was probably Novara in Piedmont.[4] He served as chaplain to Pope Urban IV, Pope Adrian V, Pope Nicholas IV, and Pope Boniface VIII.[2] His contemporary Roger Bacon cited Campanus as one of the two "good" (but not "perfect") mathematicians[5] indicating that Bacon considered Campanus as excellent[4] or one of the greatest mathematicians of their time.[1] A number of benefices were conferred upon him and he was relatively wealthy at the time of his death.[2] He died at Viterbo in 1296.[4] The crater Campanus on the Moon is named after him.[6]
