Text U of the rongorongo corpus, carved on a beam, also known as Honolulu tablet 2 or Honolulu 3628, is one of two dozen surviving rongorongo texts.
A charred, worm-eaten, and heavily corroded beam, 70.5 × 8 × 2.6 cm of unknown wood.
The area of visible inscription on side a (pictured) measures 14 × 5 cm, punctuated with a knothole.
Métraux (1938) said of the Honolulu tablets T and U that, Collector J. L. Young of Auckland purchased three of the Honolulu tablets circa 1888 "from Rapanui through a reliable agent", who Fischer thinks was probably Alexander Salmon, Jr.
As the two sides were written by different hands, the distinction of recto vs. verso may be irrelevant.
