(also spelt agna
) was, according to Varro, the
Italian name, but, according to Columella and Isidore, the common Baetican
name of the actus quadratus.
] An old writer, quoted by
Salmasius, says “agnua habet pedes XIIII. cccc,” i. e. 14,400
square feet. It is very doubtful whether the word is connected with the
seeing that the measure is so very different, and
that it is quite uncertain to what language acna
belongs. (Varro, R. R.
5.1.5; Schneider, Comment. ad ll.
15.15; Salmasius, ad
Solin. p. 481.)
