A gentle housewife mars the household. [ English Proverb, collected by George Herbert ]

An eye like Mars, to threaten or command. [ William Shakespeare ]

How many cowards, whose hearts are all as false
As stairs of sand, wear yet upon their chins
The beards of Hercules and frowning Mars,
Who, inward search'd, have livers white as milk. [ William Shakespeare ]

To speak of a usurer at the table mars the wine. [ English Proverb, collected by George Herbert ]

As much by Mars as by Minerva; as much by courage as by wisdom. [ Proverb ]

As much for Mars as for Mercury; as well qualified for war as for business.

A town, before it can be plundered and deserted, must first be taken; and in this particular Venus has borrowed a law from her consort Mars. A woman that wishes to retain her suitor must keep him in the trenches; for this is a siege which the besieger never raises for want of supplies, since a feast is more fatal to love than a fast, and a surfeit than a starvation. Inanition may cause it to die a slow death, but repletion always destroys it by a sudden one. [ Colton ]
