“I Saw Three Ships (Come Sailing In)” is an English Christmas carol, listed as number 700 in the Roud Folk Song Index. The earliest printed version of “I Saw Three Ships” is from the 17th century, possibly Derbyshire, and was also published by William Sandys in 1833. The song was probably traditionally known as “As I Sat On a Sunny Bank”, and was particularly popular in Cornwall. The modern lyrics are from an 1833 version by the English lawyer and antiquarian William Sandys, and consist of nine verses.
