Physical Description

Isumbras Took IV was the twenty-eighth Thain of the Shire.


Isumbras was the third child, and second son, of Thain Gerontius. His father's office passed to his elder brother Isengrim III, but because of their father's longevity, Isengrim's reign did not last long. As he left no heir, Isumbras became Thain at the age of ninety-two, even older than his brother was. He served for nine years before he dies, and the office passed to his son Fortinbras II.[1]


"Isumbras" is of French and Anglo-Saxon origin and means "iron-arm". It comes from the French bras meaning "arm", and the Anglo-Saxon and Middle High German word isen which means "iron".[2]

Tolkien likely got the name from Sir Isumbras, an English medieval romance about a man who suffers a lifetime of hardship but who finds happiness in his latter years.
