Compass (drawing tool) (Wikipedia)A compass, more accurately known as a pair of compasses, is a technical drawing instrument that can be used for inscribing circles or arcs. As dividers, it can also be used as a tool to mark out distances, in particular, on maps. Compasses can be used for mathematics, drafting, navigation and other purposes.

Thirteen Ways of Looking at Art (salmagundi.skidmore.edu)Art is useless, said Wilde. Art is for art’s sake—that is, for beauty’s sake. But why do we possess a sense of beauty to begin with? A question we will never answer. Perhaps it’s just a kind of superfluity of sexual attraction. Nature needs us to feel drawn to other human bodies, but evolution is imprecise. In order to go far enough, to make that feeling strong enough, it went too far. Others are powerfully lovely to us, but so, in a strangely different, strangely similar way, are flowers and sunsets. Art, in turn, this line of thought might go, is a response to natural beauty. Stunned by it, we seek to rival it, to reproduce it, to prolong it. Flowers fade, sunsets melt from moment to moment; the love of bodies brings us grief. Art abides. “When old age shall this generational waste, / Thou shalt remain.”
