Frankincense in the context of Boswellia frereana

A resin is a solid or highly viscous liquid that can be converted into a polymer. Resins may be biological or synthetic in origin, but are typically harvested from plants. Resins are mixtures of organic compounds insoluble in water, predominantly terpenes. Technically, resins should not be confused with gums, which consist predominantly of water-soluble polysaccharides, although these two terms are often interchangeable in the less formal context. Common resins include pine oleoresins, amber, hashish, frankincense, myrrh and the animal-derived resin, shellac. Resins are used in varnishes, adhesives, food additives, incenses and perfumes.

Resins protect plants from insects and pathogens, and are secreted in response to injury. Resins repel herbivores, insects, and pathogens, while the volatile phenolic compounds may attract benefactors such as predators of insects that attack the plant.

In Christianity, the Biblical Magi (/ˈmeɪdʒaɪ/ MAY-jy or /ˈmædʒaɪ/ MAJ-eye; singular: magus), also known as the Three Wise Men, Three Kings, and Three Magi, are distinguished foreigners who visit Jesus after his birth, bearing gifts of gold, frankincense, and myrrh in homage to him. In Western Christianity, they are commemorated on the feast day of Epiphany—sometimes called "Three Kings Day"—and commonly appear in the nativity celebrations of Christmas. In Eastern Christianity, they are commemorated on Christmas day.

The Magi appear solely in the Gospel of Matthew, which states that they came "from the east" (Greek: ἀπὸ ἀνατολῶν, romanized: apo anatolōn) to worship the "one who has been born king of the Jews". Their names, origins, appearances, and exact number are unmentioned and derive from the inferences or traditions of later Christians. In Western Christianity and Eastern Orthodox Christianity, they are usually assumed to have been three in number, corresponding with each gift; in Syriac Christianity, they often number twelve. Likewise, the Magi's social status is never stated: although some biblical translations describe them as astrologers, they were increasingly identified as kings by at least the third century, which conformed with Christian interpretations of Old Testament prophecies that the messiah would be worshipped by kings.

The incense trade route was an ancient network of major land and sea trading routes linking the Mediterranean world with eastern and southern sources of incense, spices and other luxury goods, stretching from Mediterranean ports across the Levant and Egypt through Northeast Africa and Arabia —through both the sea and the land along the Red Sea— to India and beyond. These routes collectively served as channels for the trading of goods such as Arabian frankincense and myrrh; Indian spices, precious stones, pearls, ebony, silk and fine textiles; and from the Horn of Africa, rare woods, feathers, animal skins, Somali frankincense, gold, and slaves. The incense land trade from South Arabia to the Mediterranean flourished between roughly the 3rd century BC and the 2nd century AD.

Dhofar (Arabic: ظُفَّار, romanized: Ẓuffār) is the largest of the 11 governorates in the Sultanate of Oman by area. It lies in southwestern Oman, bordered on the west by Al Mahrah Governorate of Yemen, on the north by the Eastern Province of Saudi Arabia, on the east by Al Wusta Governorate, and on the south by the Arabian Sea, part of the Indian Ocean. It is a rather mountainous area that covers 99,300 km (38,300 sq mi) and had a population of 416,458 in the 2020 census. Salalah is the largest city and capital of the governorate. Historically, the region was a source of frankincense. The local dialect of Arabic is Dhofari Arabic, which is distinct from that used in the rest of Oman and in Yemen.

The Adoration of the Magi or Adoration of the Kings or Visitation of the Wise Men is the name traditionally given to the subject in the Nativity of Jesus in art in which the three Magi, represented as kings, especially in the West, having found Jesus by following a star, lay before him gifts of gold, frankincense, and myrrh, and worship him. It is related in the Bible by Matthew 2:11: "On entering the house, they saw the child with Mary his mother; and they knelt down and paid him homage. Then, opening their treasure chests, they offered him gifts of gold, frankincense, and myrrh. And having been warned in a dream not to return to Herod, they left for their own country by another path".

Christian iconography considerably expanded the bare account of the Biblical Magi described in the Gospel of Matthew (2:1–22). By the later Middle Ages this drew from non-canonical sources like the Golden Legend by Jacobus de Voragine. Artists used the expanded Christian iconography to reinforce the idea that Jesus was recognized, from his earliest infancy, as king of the earth. The adoration scene was often used to represent the Nativity, one of the most indispensable episodes in cycles of the Life of the Virgin as well as the Life of Christ.

The Burseraceae are a moderate-sized family of 17-19 genera and about 540 species of woody flowering plants. The actual numbers given in taxonomic sources differ according to taxonomic revision at the time of writing. The Burseraceae are also known as the torchwood family, the frankincense and myrrh family, or simply the incense tree family. The family includes both trees and shrubs; its species are native to tropical regions of Africa, Asia, Australasia, and the Americas.

Because of taxonomic revision, as the family size (in terms of genera and species) differs according to the time period of study; so, too, does the family's higher-level relationships, including order. Burseraceae is a genetically-supported monophyletic group since APG III and is frequently cited within the Sapindales. It is recognized as a sister group to the Anacardiaceae.

Maritime history of Somalia refers to the seafaring tradition of the Somali people. It includes various stages of Somali navigational technology, shipbuilding and design, as well as the history of the Somali port cities. It also covers the historical sea routes taken by Somali sailors which sustained the commercial enterprises of the historical Somali kingdoms and empires, in addition to the contemporary maritime culture of Somalia.

In antiquity, the ancestors of the Somali people were an important link in the Horn of Africa connecting the region's commerce with the rest of the ancient world. Somali sailors and merchants were the main suppliers of frankincense, myrrh and spices, items which were considered valuable luxuries by the Ancient Egyptians, Phoenicians, Mycenaeans and Babylonians. During the classical era, several ancient city-states such as Ophir at the time Berbera and Ras Hafun and Hiran then part of Mogadishu competed with the Sabaeans, Parthians and Axumites for the wealthy Indo-Greco-Roman trade also flourished in Somalia. In the Middle Ages, several powerful Somali empires dominated the regional trade including the Ajuran Sultanate, the latter of which maintained profitable maritime contacts with Arabia, India, Venetia, Persia, Egypt, Portugal and as far away as China. This tradition of seaborne trade was maintained in the early modern period, with Berbera being the pre-eminent Somali port during the 18th–19th centuries.

Sacred herbs are herbs that are considered sacred in some religions. Herbs such as myrrh (Commiphora myrrha), ague root (Aletris farinosa), and frankincense (Boswellia spp) in Christianity, Nine Herbs Charm in the partially Christianized Anglo-Saxon pagan, and a form of basil called tulsi—revered as a Hindu goddess for its medicinal value—are utilized in their rites and rituals.

Boswellia sacra, also known as Boswellia carteri and others, and commonly called the frankincense tree or the olibanum tree, is a tree in the genus Boswellia, in the Burseraceae family, from which frankincense, a resinous dried sap, is harvested. The olibanum tree is a plant native to the countries of Oman and Yemen, in the south of the Arabian Peninsula, and to Somalia and Ethiopia, in the Horn of Africa. In 2012, it was replanted in Israel in the Middle East, 1,500 years after dying out there.

Boswellia is a genus of trees in the family Burseraceae, known for its fragrant resin. The biblical incense frankincense is an extract from the resin of the tree Boswellia sacra, and is now produced also from B. frereana. Boswellia species are moderate-sized flowering plants, including both trees and shrubs.
