In art, S. Patrick is usually represented expelling serpents and other reptiles from the island with his pastoral staff, or holding a shamrock leaf. He is said to have had the golden rod of Jesus, given him by a hermit in Gaul, wherewith he smote and slew the Peishta-More, or Monster of the Lakes, and this is also frequently represented in art. S. GERTRUDE, V. ABSS. OF NIVELLES. (A.D. 664.) [Roman Martyrology, and those of Bede, Usuardus, and Ado. German, Gallican, and Belgian Martyrologies commemorate the elevation of her relics on Feb. 10th; and the translation on May 30th and April 10th. Authorities:--A Life, by an eye-witness of her acts, apparently a canon or chaplain of the monastery. He says, "I have endeavoured in writing to narrate what I have seen myself or heard from trustworthy witnesses." Another Life, written in polished style from the testimony of Rinchin, an acquaintance of S. Gertrude.] S. Gertrude was the daughter of the B. Pepin of Landen (Feb. 21st) and S. Itta or Iduberga (May 8th). Her brother, Grimoald, succeeded her father. Her sister, S. Begga (Dec. 17th), who married duke Ansigis, and became the mother of Pepin, the father of Charles Martel. S. Aldegund (Jan. 30th), and S. Waltrudis (April 9th), the wife of S. Vincent (July 14th), were also relatives of hers. [Illustration: S. GERTRUDE OF NIVELLES. After Cahier. March 17.] Dagobert, king of the Franks, who had made Pepin of Landen mayor of the palace, asked him to allow him to give Gertrude in marriage to a young Frank nobleman. The father hesitated, knowing that his daughter desired to lead the religious life, and the king seeing his reluctance to force his daughter to a match for which she was not inclined, sent for Gertrude herself, then aged about ten, and endeavoured to persuade her to accept the hand offered her. But Gertrude resolutely refused, declaring that she would have no other bridegroom but Jesus Christ. The king dismissed the child, and she returned to her mother, who educated her in the love and fear of God. On the death of Pepin, in 646, Iduberga, following the advice of S. Amandus, bishop of Maestricht, built the celebrated convent of Nivelles, and retired into it with her daughter, then aged fourteen. They were soon followed by a numerous company of maidens, and a community was formed, to which the blessed Iduberga gave rules. The sisters were called canonesses, and Iduberga appointed her daughter abbess. Thus the mother obeyed the child. The holy woman spent twelve years in this peaceful retreat, and died in the odour of sanctity. After her mother's death, Gertrude made some alterations in the community. She instituted canons, who should attend to the temporal affairs of the house, whilst she devoted herself to the internal government of the sisterhood, and their spiritual training. For this latter purpose Gertrude devoted herself especially to the study of Holy Scripture, and nearly learnt the whole by heart.
