Brother Methuselah, sometimes known as Old Methuselah, was a bespectacled wise old mouse, and Gatekeeper at Redwall Abbey. He was a scholar, well-known for Abbey record-keeping and chronicling, and spent most of his time alone. He was also known for being able to understand almost any creature, as he had the gift of tongues. He was said to be the oldest mouse ever to live in Redwall Abbey.
In his old age, he befriended Matthias, the young mouse destined to follow in Martin the Warrior's footsteps. Together, they discovered an ancient riddle carved behind the tapestry in Great Hall, which named Matthias as Martin's successor. The riddle also led to the finding of the sepulcher of Martin, as well as his armor and (much later) his Sword.
When a stolen piece of the tapestry was recovered from Cluny the Scourge, Methuselah repaired the damage, sewing the tapestry back together so skillfully, it looked as though it had never been torn. It was just as he was finishing this task that the thief Chickenhound came running through the Hall with a bag of stolen goods, looking for a means of escape. Methuselah bravely confronted Chickenhound and tried to stop him; however, the fox slew him by hitting him over the head with the heavy sack harder than he meant.
Methuselah then came to Matthias in a dream to continue his quest to find the sword alone.
Methuselah was mentioned in Mattimeo as being able to read Loamscript. Abbot Mordalfus later discovered the fact that Abbot Mortimier and Methuselah called the ants "the little folk"; this fact helped to solve a riddle which in turn led to the discovery of the statue of Abbess Germaine. He was the author of the text Old Methuselah's Index of Bird Ailments and Remedies.
Redwall TV Series
In the TV series, after Methuselah was fatally injured by Chickenhound, he lingered for a few days before dying (in the book, he passed away almost instantaneously). Also, in the TV series, Methuselah was killed before the recovery of the tapestry piece, and not after.
- In the Bible, Methuselah was a wise man who lived far beyond an average lifetime.
