San Giorgio Maggiore in Venice. The martyr twins are invoked in the Canon of the Mass in the prayer known as the Communicantes (from the first Latin word of the prayer): "In communion with the whole Church, they venerate above all others the memory of the glorious ever-virgin Mary, Mother of our God and Lord, Jesus Christ, then of blessed Joseph, husband of the Virgin, your blessed Apostles and Martyrs, Peter and Paul, Andrew, James, ...John and Paul, Cosmas and Damian and all your Saints: grant through their merits and prayers that in all things we may be defended by the help of your protection." They are also invoked in the Litany of the Saints, and in the older form of the Roman rite, in the Collect for Thursday in the Third Week of Lent, as the station church for this day is Santi Cosma e Damiano. Their feast day in the General Roman Calendar, which had been on 27 September, was moved in 1969 to 26 September because 27 September is the dies natalis ("day of birth" into Heaven) of Vincent de Paul, now more widely venerated in the Latin Church. In Canada it has been moved to 25 September (as 26 September is the Feast of the Canadian Martyrs in Canada). Sts Cosmas and Damian are regarded as the patrons of physicians, surgeons, and pharmacists and are sometimes represented with medical emblems. They are also regarded as the patron saints of twins. In Brazil, the twin saints are regarded as protectors of children, and 27 September is commemorated, especially in Rio de Janeiro, by giving children bags of candy with the saints' effigy printed on them and throughout the entire state of Bahia where Catholics and adepts of Candomblé religion offer typical food such as caruru. The ritual consists of first offering the food to seven children that are no older than seven years old and then having them feast while sitting on the floor and eating with their hands. The Church of Saints Cosmas and Damian, in Igarassu, Pernambuco is Brazil's oldest church, built in 1535. In the UK Damian is the dexter side supporter in the coat of arms of the British Dental Association. Cosmas and Damian are venerated every year in Utica, New York at St. Anthony's Parish during the annual pilgrimage which takes place on the last weekend of September (close to the 27
