Roman surname.
[1] M., Q. Horse breeder
Cited by Varro (Rust. 2,7,1) as a distinguished horse breeder. His (probably invented) cognomen Equicolus, which indicates this activity, may have been interpreted by Varro as Aequicolus, so that a later period reveals a Septimus M. as the first king of the Aequiculi (Lib. de praenominibus 1).
