Pope Saint Alexander I was Bishop of Rome from about 106 to 115. The Holy See's Annuario Pontificio (2008) identifies him as a Roman who reigned from 108 or 109 to 116 or 119. Some believe he suffered martyrdom under the Roman Emperor Trajan or Hadrian, but this is improbable. In the article on Saint Alexander I in the 1907 Catholic Encyclopedia, Thomas Shahan judges inaccurate the tradition that this Pope inserted into the Roman Canon the narration of the Last Supper (the Qui pridie). Pope Alexander I is also said to have introduced the use of blessing water mixed with salt for the purification of Christian homes from evil influences, and the custom of mixing water with the sacramental wine. This too is considered unlikely.
