Petrel 3692 Petrifaction Arezzo. The family eventualh settled at Avignon and in 1326 Petrarch entered the priesthood. In 1327 he first saw Laura (prob- ably the wife of Hugo de Sacle), \\ho was destined to inspire all his love poetry. His friendship with the great Roman family of the Colonna dates from this period. In 13^3-7 he travelled in France, Belgium, and Ger- many, collecting MSS. of the classics. In 1340 he accepted the poet's laurel wreath from the Roman Senate, being crowned at Easter, 1341. On April 6, 1348, his Laura died; and though he went once again to Vaucluse (near Avignon), he left his beloved spot for good in I3S3- Petrarch may be considered as the earliest of the great humanists of the Renaissance. It is upon his Latin works that he based his hope of immortality. These works may be divided into poems, moral and religious prose works, historical prose works, minor writ- ings, and letters. The twelve eclogues which compose the Carmen Bucolicum (1347-56) narrate, in pastoral guise, events of the poet's life and times. Among works testifying to Petrarch's mysticism and religious feeling the finest is perhaps the Secretum or De Con- temptn Mundi (c. 1342), consisting of three dialogues between the author and St. August- ine. The De Vita Solitaria (1346-56) cele- brates the hermits of all ages. The Psalmi Pcenitentiales were written to solace the poet's grief. The Letters (1326-74) are in- valuable as a record of the author and his age, and are conspicuous for their literary merit. The rare and beautiful Canzoniere consist of 317 sonnets with canzoni, scstine, ballads, and madrigals, nearly all love poems, inspired by Laura.

Stormy Petrel Petrel (Procellaria) > a genus of sea birds of the family which includes the albatrosses, shearwaters, fulmars, and petrels proper, and is allied to the gulls. The true petrels, of which there are a number of widely distri- buted species, are long-winged birds of pow- erful flight. The best-known species is the Stormy Petrel (P. pdagica) or Mother Carey's Chicken, which is scarcely larger than a lark, and is the smallest web-footed bird known. The bird is essentially oceanic, and rarely comes on shore save at the breeding season, when it lays a single egg in a burrow, a rock crevice, or even on the bare ground. Because of its frequent appearance before or during stormy weather, and possibly also be- cause of its blackness, it is regarded by sailors as a bird of evil omen. Petri, Laurentius (1499-1573), Swedish reformer, studied under Luther at Witten- berg; was made first Protestant archbishop of Upsala. Along with his brother Olaus he succeeded in converting Sweden to the Re- formed doctrines, and with him superintend- ed the translation of the Bible into Swedish Petri, Olaus (1493-1552), Swedish re- former, brother of Laurentius. He studied under Luther and Melanchthon at Witten- berg. By Gustavus i. he was recalled to act as town clerk of Stockholm, to preach the doctrines of the Reformation, and in 1531 to become chancellor of the kingdom. Petri was the first to introduce the Reformation into Sweden. In 1526 he translated the New Tes- tament into Swedish, and in 1541, with his brother Laurentius, the Old Testament. He also compiled the first Swedish hymn book. Petrie, William Matthew Flinders (1853-1942), English Egyptologist, was born in Charlton, Kent. In i
