Frankincense

The atoms scoped to Judaism, Christianity and Omani household life describe four unrelated reasons to burn the same resin, and reading them together says more about frankincense than any one alone.

The ketoret of Exodus 30 lists frankincense as one of four required spices, alongside galbanum, onycha and stacte. Rabbinic tradition holds it to be the only one of the four that is fragrant by itself, the other three being sharp or unpleasant until compounded together, so a blend read as uniformly sweet depended on one ingredient covering for three others. The recipe was also fenced: Exodus 30:37 forbids making the same compound for private use, so this particular formula existed as consecrated and could not be copied at home, a restriction with no equivalent among the other incenses on this site.

The thurible reads the same smoke differently again. Catholic and Orthodox liturgy pairs the censing of altar, gospel book and coffin with Psalm 141, "let my prayer rise before you as incense," so that the smoke's plain upward drift is doing the theological work rather than illustrating it.

Neither reading describes how most frankincense actually burns today. In Oman and Yemen it is a household object rather than an occasion: a mabkhara smoulders in the front room to welcome an ordinary guest, and the smell is furniture rather than ceremony, the opposite of both the fenced ketoret and the censed altar.

Frankincense is a resin used as incense: the hardened gum of Boswellia trees of Arabia and the Horn of Africa. Burned since antiquity in Egyptian, Jewish, Christian and other rites, it is among the most widely used ritual incenses, and in Western planetary correspondence is given to the Sun.

Material and correspondence

In the Western system of ritual correspondences it is set under the Sun and the element of Fire. Such planetary and elemental attributions belong to the Western esoteric tradition of correspondences, drawn from writers such as Agrippa and codified in the modern period by the Hermetic Order of the Golden Dawn; the material's use as incense is far older and cuts across many cultures. It is described here within that documented tradition of ritual perfume.

A resin and its trade route

The resin is tapped from several related Boswellia species, chiefly Boswellia sacra of Oman and Yemen and Boswellia papyrifera and B. frereana of the Horn of Africa, and for over a thousand years before the common era it moved north along the overland Incense Route through southern Arabia to the Mediterranean, a trade substantial enough to help fund the rise of caravan cities such as Petra. It is named among the gifts brought to the infant Jesus at Matthew 2:11, and remains in continuous liturgical use today in the thurible of Catholic and Orthodox Christian worship, a use unbroken since antiquity rather than a modern revival.
