Summary The addition of ‘fire’ to the European battle repertoire resulted in the close-order drill for manoeuvres of the line. Begun in late sixteenth-century Netherlands and perfected in eighteenth-century Prussia under Frederick the Great, the drill's precision marching evolved into a military science which conceived what infantry acquired through rigorous training as a lawful ‘second nature’ of men. In contrast, the liberal Webers' 1836 locomotion research orientation was, as was that of French skirmishing, one of natural self-regulation. Later Prussian military (...) science, restored in Imperial Germany, was merged into locomotion science. (shrink)

What we observe, through our usually limited lens, is that differential growing of space determines forms -characterized by their shape, size and coloration. As non-Euclidean geometrical mathematics have proclaimed: forms are manifestations of the curvature of space. Physics and other natural laws impose mathematical structural restrictions to biological forms. The molecules comprising any living form become arranged in specific ways in response to physical forces as well as chemical and biochemical conditions. Over time, such forms inherit additional historical restrictions that (...) make up their meaning, their semiotics. Color does not escape from this orthogenic reality. In this study, we present the colored pattern of the connexivum of Triatoma maculata, an insect vector of the etiologic agent of Chagas disease. This model is used as an example to appreciate mimicry under a heterodox and provocative approach. We unveil that beyond 1) mathematical and 2) historical semiotic restrictions of T. maculata mimesis of a yellowish-black alternating pattern, there are also 3) artistic interpretations; where metaphysics of life, beyond human perspective, is included.
