Ostrich Egg
The egg of the ostrich (genus ''Struthio'') is the largest of any living bird. The shell has a long history of use by humans as a container and for decorative artwork. The eggs are not commonly eaten. Biology The female common ostrich lays her fertilized eggs in a single communal nest, a simple pit, deep and wide, scraped in the ground by the male. The dominant female lays her eggs first, and when it is time to cover them for incubation she discards extra eggs from the weaker females, leaving about 20 in most cases. A female common ostrich can distinguish her own eggs from the others in a communal nest. Ostrich eggs are the largest of all eggs, though they are actually the smallest eggs relative to the size of the adult bird — on average they are long, wide, and weigh , over 20 times the weight of a chicken's egg and only 1 to 4% the size of the female. They are glossy cream-colored, with thick shells marked by small pits. The eggs are incubated by the females by day and by ...

Ostrich Eggs In A Nest At An Ostrich Farm, South Pasadena, Ca
Ostriches are large flightless birds of the genus ''Struthio'' in the order (biology), order Struthioniformes, part of the infra-class Palaeognathae, a diverse group of flightless birds also known as ratites that includes the emus, Rhea (bird), rheas, and Kiwi (bird), kiwis. There are two living species of ostrich: the common ostrich, native to large areas of sub-Saharan Africa and the Somali ostrich, native to the Horn of Africa. The common ostrich was also historically native to the Arabian Peninsula, and ostriches were present across Asia as far east as Mongolia during the Late Pleistocene and possibly into the Holocene climatic optimum, Holocene. They lay the largest eggs of any living land animal. With the ability to run at 70 km/h (43.5 mph), they are the fastest birds on land. They are farmed worldwide, particularly for their feathers as they are used as decoration and feather dusters. Their skin is also used for leather products. They are the heaviest living bir ...

Brera Madonna
The ''Brera Madonna'' (also known as the ''Pala di Brera'', the Montefeltro Altarpiece or Brera Altarpiece) is a painting by the Italian Renaissance master Piero della Francesca, executed in 1472–1474. It is housed in the Pinacoteca di Brera of Milan, where it was deposited by Napoleon. The work, of a type known as a ''sacra conversazione'', was commissioned by Federico III da Montefeltro, Duke of Urbino, to celebrate the birth of Federico's son, Guidobaldo. According to other sources, it would celebrate his conquest of several castles in the Maremma. Dating The painting was executed between 1472 and 1474; the ''terminus ante quem'' is established by the absence from Federico's figure of the insignia of the Order of the Garter, which he received in the later year. When it was rediscovered at the Brera at the end of the 19th century, the painting was so disfigured by darkened varnish it was attributed to Fra Carnevale (Bartolomeo di Giovanni Corradini), as Piero's use of oil ...

Piero Della Francesca
Piero della Francesca (, also , ; – 12 October 1492), originally named Piero di Benedetto, was an Italian painter of the Early Renaissance. To contemporaries he was also known as a mathematician and geometer. Nowadays Piero della Francesca is chiefly appreciated for his art. His painting is characterized by its serene humanism, its use of geometric forms and perspective. His most famous work is the cycle of frescoes ''The History of the True Cross'' in the church of San Francesco in the Tuscan town of Arezzo. Biography Early years Piero was born Piero di Benedetto in the town of Borgo Santo Sepolcro, modern-day Tuscany, to Benedetto de' Franceschi, a tradesman, and Romana di Perino da Monterchi, members of the Florentine and Tuscan Franceschi noble family.

Virgin Mary
Mary; arc, ܡܪܝܡ, translit=Mariam; ar, مريم, translit=Maryam; grc, Μαρία, translit=María; la, Maria; cop, Ⲙⲁⲣⲓⲁ, translit=Maria was a first-century Jewish woman of Nazareth, the wife of Joseph and the mother of Jesus. She is a central figure of Christianity, venerated under various titles such as virgin or queen, many of them mentioned in the Litany of Loreto. The Eastern and Oriental Orthodox, Church of the East, Catholic, Anglican, and Lutheran churches believe that Mary, as mother of Jesus, is the Mother of God. Other Protestant views on Mary vary, with some holding her to have considerably lesser status. The New Testament of the Bible provides the earliest documented references to Mary by name, mainly in the canonical Gospels. She is described as a young virgin who was chosen by God to conceive Jesus through the Holy Spirit. After giving birth to Jesus in Bethlehem, she raised him in the city of Nazareth in Galilee, and was in Jerusal ...

Virgin Birth Of Jesus
The virgin birth of Jesus is the Christian doctrine that Jesus was conceived by his mother, Mary, through the power of the Holy Spirit and without sexual intercourse. It is mentioned only in and , and the modern scholarly consensus is that the narrative rests on very slender historical foundations. The ancient world had no understanding that male semen and female ovum were both needed to form a fetus; this cultural milieu was conducive to miraculous birth stories, and tales of virgin birth and the impregnation of mortal women by deities were well known in the 1st-century Greco-Roman world and Second Temple Jewish works. Christians—Catholics, Protestants, Eastern Orthodox, Oriental Orthodox—traditionally regard the doctrine as an explanation of the mixture of the human and divine natures of Jesus. The Eastern Orthodox Churches accept the doctrine as authoritative by reason of its inclusion in the Nicene Creed, and the Catholic Church likewise holds it authoritative for fa ...

Eastern Orthodox
Eastern Orthodoxy, also known as Eastern Orthodox Christianity, is one of the three main branches of Chalcedonian Christianity, alongside Catholicism and Protestantism. Like the Pentarchy of the first millennium, the mainstream (or "canonical") Eastern Orthodox Church is organised into autocephalous churches independent from each other. In the 21st century, the number of mainstream autocephalous churches is seventeen; there also exist autocephalous churches unrecognized by those mainstream ones. Autocephalous churches choose their own primate. Autocephalous churches can have jurisdiction (authority) over other churches, some of which have the status of "autonomous" which means they have more autonomy than simple eparchies. Many of these jurisdictions correspond to the territories of one or more modern states; the Patriarchate of Moscow, for example, corresponds to Russia and some of the other post-Soviet states. They can also include metropolises, bishoprics, parishes, monas ...

Renaissance
The Renaissance ( , ) , from , with the same meanings. is a period in European history marking the transition from the Middle Ages to modernity and covering the 15th and 16th centuries, characterized by an effort to revive and surpass ideas and achievements of classical antiquity. It occurred after the Crisis of the Late Middle Ages and was associated with great social change. In addition to the standard periodization, proponents of a "long Renaissance" may put its beginning in the 14th century and its end in the 17th century. The traditional view focuses more on the early modern aspects of the Renaissance and argues that it was a break from the past, but many historians today focus more on its medieval aspects and argue that it was an extension of the Middle Ages. However, the beginnings of the period – the early Renaissance of the 15th century and the Italian Proto-Renaissance from around 1250 or 1300 – overlap considerably with the Late Middle Ages, conventionally da ...

Its connection to the ocean is in the south, through the Bab el Mandeb strait and the Gulf of Aden. To its north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez (leading to the Suez Canal). It is underlain by the Red Sea Rift, which is part of the Great Rift Valley.

Bāḍiʿ
Bāḍiʿ was a medieval African port on the Red Sea. It was the first port established by the Arabs in the Bilād al-Sūdān and flourished between about 600 and 1100. It was a merchant settlement conducting trade between its hinterland and Arabia. It does not appear to have fallen under the authority of any established state.Yusuf Fadl Hasan (1967), ''The Arabs and the Sudan: From the Seventh to the Early Sixteenth Century'' (Edinburgh University Press), pp. 64–66. Bāḍiʿ was located south of the Gulf of ʿAḳīḳ, just offshore on the island of Er Rih (''al-Rīḥ'') in what is now Sudan, near the border with Eritrea. The village of ʿAḳīḳ, which gives its name to the gulf, lies some to the north of the site. Older authorities, such as ''The Red Sea and Gulf of Aden Pilot'', identify the ruins of Er Rih with ancient Ptolemais Theron, but J. W. Crowfoot argues that Ptolemais is ʿAḳīḳ and the ruins of Er Rih medieval Bāḍiʿ.John Winter Crowfoot (1911), "So ...
