Saxon language influenced the means Caedmon used to express his vision of the creation, since he lived in eighth century England, which was influenced by Saxon language and culture much more than modern England. The few thousand lines of Old English poetry that survive were written down long after their composition, because Anglo-Saxon poetry like Caedmon's was a part of an oral tradition. Caedmon sang his lines; he was illiterate. The church remained the most powerful institution of the land after the sixth century, so Caedmon's poetry uses Christ as a primary theme.
Caedmon believed he was doing the work of an angel who commanded him to sing "the Creation of all things." He believed he was granted grace by God and was working in His service. While many of the poetical works of his time focused on the daily toils of living, Caedmon wanted to express God's creation of the Earth. He did so in lyrical song. Caedmon drew from biblical literary traditions to compose his work; the Christ-figure and Lord is a primary image. Caedmon established a school of Christian poetry; his poems veer into the devotional, didactic and mystical.
Alliteration and kennings are mainstays of Old English poetry. Alliteration is the repeated use of a single consonant, which creates a highly musical tone. It is easier to recollect because each line starts with a series of alliterations. Caedmon's Hymn is below; note how many alliterations begin with "m," like in the second line, "metudaes maechti end his modgidanc" (translated, "the might of the Creator, and his thought").
Kennings are a metaphorical, two-word phrase. A kenning example would be Beowulf traversing the "whale-road," which refers to the sea, in the epic poem by the same name. In Genesis BK 1, Caedmon describes hell as a "torture-house," thus using his language to create metaphorical images.
The Old English version of Caedmon's Hymn follows:
Nu scylun hergan hefaenricaes uard
metudæs maecti end his modgidanc
uerc uuldurfadur sue he uundra gihuaes
eci dryctin or astelidæ
he aerist scop aelda barnum
heben til hrofe haleg scepen.
tha middungeard moncynnæs uard
eci dryctin æfter tiadæ
firum foldu frea allmectig
The Saxons were accustomed to living violent lives, filled with war and battlefield camaraderie. In Caedmon's books of Genesis, he used images of warfare in his vision of the figures of Christ and of God. The culture Caedmon lived in relied on servitude to a tribal lord; this influence is clear in Caedmon's books of Genesis. In these books, God appears to be a great leader in battle, rather than an omniscient God who, with a wave of his hand, banishes Lucifer's hosts to hell. He smites them and prevents them not from independence, but from attaining the glory and victory a warrior desires.
