An oxgang or bovate (Old English: oxangang; Danish: oxgang; Scottish Gaelic: damh-imir; Medieval Latin: bovāta) is an old land measurement formerly used in Scotland and England as early as the 16th century sometimes referred to as an oxgait.[1] It averaged around 20 English acres, but was based on land fertility and cultivation, and so could be as low as 15.[2]
An oxgang is also known as a bovate, from bovāta, a Medieval Latinisation of the word, derived from the Latinbōs, meaning "ox, bullock or cow". Oxen, through the Scottish Gaelic word damh or dabh, also provided the root of the land measurement 'daugh'.
"in the eastern district there is a uniform system of land denomination consisting of 'dabhachs', 'ploughgates' and 'oxgangs', each 'dabhach' consisting of four 'ploughgates' and each 'ploughgate' containing eight 'oxgangs'.
"As soon as we cross the great chain of mountains [the Grampian Mountains] separating the eastern from the western waters, we find a different system equally uniform. The 'ploughgates' and 'oxgangs' disappear, and in their place we find 'dabhachs' and 'pennylands'. The portion of land termed a 'dabhach' is here also called a 'tirung' or 'ounceland', and each 'dabhach' contains 20 pennylands."
