Michael Baxandall has noted: “We do not explain pictures: we explain remarks about pictures-or rather, we explain pictures only in so far as we have considered them under some verbal description or specification . . .
There is no limit to how one could make a description. Descriptions are as much as you make them to be. A machete can be viewed in many perspectives and because of that there can be more than one description of this object. A person could start off a description with the physical features and slowly work their way towards describing it's capabilities and it's purpose.
