Note: the dexter division of the third quarter is not drawn correctly here.  The tinctures shown cannot be verified from the stonework version in the San Jeronimo coa, but there should be two pales, not a simple division by pale.
This colorised version shows different tinctures for the field in question.
This is an attributed coat of arms, used posthumously by Gonzalo's wife for the family tomb where she herself was also buried.

It appears that Gonzalo himself used a more simple quartered version showing only Fernández de Córdoba, Manrique de Lara, Enríquez and Mendoza, see here ("Estas son las armas del Gran Capitan a quien fue dirigida la presente obra").
