"On the feast of St. Mark rogations take place, which are called the major rogations or Litanies. The word Rogation is of Latin derivation, and means a petition, a prayer. A litany, originally meant a common, alternately spoken prayer. In the course of time this word was transferred to rogation, so that, in the language of the Church, Litany and rogation are synonymous. The rogations of St. Mark?s day are called the major rogations or Litanies, because from the beginning they were held with greater solemnity than the rogations in Rogation Week. These rogations on the feast of St. Mark are of very ancient date, for they can be traced back to St. Gregory the Great, who introduced them in the year 590. Thy have for their object to beg God in the spirit of humility and penance, that He may graciously protect us from all those evils with which natures threatens us. For, on account of the sins by which we have desecrated it, nature is in opposition to us, and causes us many damages. God being the Lord of nature, we supplicate Him by united prayers, that He may avert from us everything dangerous to our person and property." (The Pulpit Orator, page 147, By Rev. John Evangelist Zollner, 1884.)
"The object of these days? devotions is to ask of God, from whom every good and perfect gift proceeds, that He would be pleased to give and preserve the fruits of the earth, and bestow upon His creatures all those temporal blessings that are necessary for them in the course of their mortal pilgrimage. Besides the actual graces received by the devotions of the Rogations Days, the fact itself of being reminded to have recourse to Almighty God for temporal blessings is of great advantage in this material age, when the all-sufficiency of man has become one of the leading dogmas of misguided persons." (The Litanies, The Sacramentals of the Holy Catholic Church Page 197.)
