In the realm of Irish mythology, Bodb Derg, known as Bodhbh Dearg in Middle and Modern Irish, is depicted as the offspring of Eochaid Garb or the Dagda, the latter being central to many myths. He holds the notable position of being the successor to the Dagda as the ruler of the Tuatha Dé Danann.

Etymology of Bodb Derg

The name “Bodb” may indeed share roots with “bádhbh,” suggesting a similar phonetic quality; thus, Bodb Derg can be interpreted as “Red Crow.” Old Irish manuscripts showcase a flexible approach to spelling, leading to occasional variations in the name of the mythological figure Badb.

Myths Surrounding Bodb Derg

In “Aislinge Óenguso,” Aengus seeks his brother Bodb’s assistance in his quest for the perfect partner, identifying the beautiful Caer Ibormeith with Bodb’s help. During the troubled period following the Tuatha Dé Danann’s loss at the Battle of Tailtiu, Bodb is appointed king in the tale known as “The Children of Lir,” shortly before the Tuatha Dé retire into the síde (hills). Bodb’s election to kingship is largely attributed to his status as the eldest son of the Dagda, and he quickly becomes a father to numerous deities. Despite his recognized authority, Lir, one of his peers, openly challenges Bodb’s position and refuses to pay him respect. In a display of diplomacy, Bodb suggests restraint toward Lir and later attempts to repair their relationship by offering him the hands of two of his daughters. Unfortunately, both unions encounter sorrow.

In various iterations of the mythology, Manannan is also recognized as the supreme ruler alongside Bodb Derg during the descent of the Tuatha Dé Danann into the sidhe. Manannan commands significant respect as the “chief of the kings,” governing the distribution of sidhe mounds to his kin.

As the ruler of the Munster síde, with Lén as his blacksmith, Bodb Sída ar Femen plays a pivotal role in the prologue of the legendary tale “Táin Bó Cuailnge.” He is linked to a dispute between his swineherd and that of the Connacht king, a conflict that leads to the transformation of the swineherds into the legendary bulls Donn Cuailnge and Finnbennach—key figures in the famed cattle raid.

In another tale from the Fenian cycle, Bodb Derg leads the Tuatha Dé Danann to support the Fianna during the Battle of Ventry, underlining his significance in various mythic narratives.
