Illud vero (ab Aristotele animadversum, a quo pleraque) quis potest non mirari: grues cum loca calidiora petentes maria transmittant, trianguli efficere formam; eius autem summo angulo aer ab is adversus pellitur, deinde sensim ab utroque latere, tamquam remis, ita pinnis cursus avium levatur; basis autem trianguli, quam efficiunt grues, ea tamquam a puppi ventis adiuvatur; eaeque in tergo praevolantium colla et capita reponunt; quod quia ipse dux facere non potest, quia non habet, ubi nitatur, revolat, ut ipse quoque quiescat; in eius locum succedit ex his, quae adquierunt, eaque vicissitudo in omni cursu conservatur.

45 BCE, Cicero, De Natura Deorum, volume 2, section 125:

Really, who can not be surprised by this (noticed by Aristotle, from whom comes most of this): that cranes, when they cross the seas looking for warmer places, make the shape of a triangle; for the air is pushed away from them by the top angle, then gradually on each side, as by oars, so the birds' course is elevated by the wings; as for the base of the triangle that cranes make, it is helped as though by winds from the stern; and they put their necks and heads in the back of those flying before them; because the leader itself cannot do this, because it doesn't have one, when it strains itself, it flies back, so that it can also rest; one of those which were resting behind it takes its place, and this changing of places is kept up for the whole journey.

(geometry) the base of a triangle, chord of an arc
