A walk is a line of footsteps. A sculpture is a line of stones…in a continuum with animal marks…
-Richard Long, Land Artist, in southern Algeria
‘Athar, (pl) ‘Āthār, A remain, relic, trace, vestige, footstep, track…Ma’thūr, A camel having a mark made on the bottom of his foot by an iron instrument called a Ma’thara so that his footprints upon the ground may be known.
-Lane’s Lexicon
I doubt that KhairAllah has heard of Richard Long but he can recognize the prints of a camel whose ulcerous footpad is mended with a sewn leather patch, something like ‘Āthār, in the second meaning given by Lane, Monuments from Any Time Past.
