A cradle is an infant bed which rocks but is non-mobile. [1] It is distinct from a typical bassinet which is a basket-like container on free-standing legs with wheels. A carbonized cradle was found in the remains of Herculaneum left from the destruction of the city by the eruption of Mount Vesuvius in 79 CE. [2] The Nahua or Aztec people used cradles, with an Aztec ceramic figure of a child in a cradle dated back to between 1350 and 1521 CE. [3]
