Quando i riferimenti erano allineati i custodi di questo tempio potevano predire con buona approssimazione l'avvenire delle eclissi. </p><p>Dopo le ultime scoperte archeologiche riguardanti alcune scritture trovate sui monumenti dell'<a href="/wiki/America_centrale" title="America centrale">America centrale</a>, all'<a href="/wiki/University_of_Maryland,_College_Park" class="mw-redirect" title="University of Maryland, College Park">Università del Maryland</a> si è formato un centro dove <a href="/wiki/Archeologo" title="Archeologo">archeologi</a> e <a href="/wiki/Astronomo" title="Astronomo">astronomi</a> lavorando in stretta collaborazione sono arrivati alla deduzione che alcune popolazioni come i <a href="/wiki/Maya" title="Maya">Maya</a>, <a href="/wiki/Inca" title="Inca">Inca</a> e <a href="/wiki/Aztechi" title="Aztechi">Aztechi</a>, riuscirono a determinare con un'ottima precisione i giorni in cui era probabile un'eclisse, arrivando alle stesse conclusioni a cui erano giunti i popoli del <a href="/wiki/Vecchio_Mondo" title="Vecchio Mondo">Vecchio Mondo</a>. </p> <div class="mw-heading mw-heading2"><h2 id="Note">Note</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Saros&veaction=edit&section=4" title="Modifica la sezione Note" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Saros&action=edit&section=4" title="Edit section's source code: Note"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-references-wrap mw-references-columns"><ol class="references"> <li id="cite_note-1"><a href="#cite_ref-1"><b>^</b></a> <span class="reference-text"> <cite class="citation web" style="font-style:normal"> <a rel="nofollow" class="external text" href="https://www.treccani.it/enciclopedia/saros"><span style="font-style:italic;">saros nell'Enciclopedia Treccani</span></a>, su <span style="font-style:italic;">treccani.it</span>. <small>URL consultato il 30 marzo 2021</small>.</cite></span> </li> <li id="cite_note-2"><a href="#cite_ref-2"><b>^</b></a> <span class="reference-text">Voce "saros" nel Dizionario di Italiano Garzanti, ed. 2004.</span> </li> <li id="cite_note-3"><a href="#cite_ref-3"><b>^</b></a> <span class="reference-text"> <cite class="citation web" style="font-style:normal"> <a rel="nofollow" class="external text" href="https://www.sapere.it/enciclopedia/s%C3%A0ros.html"><span style="font-style:italic;">sàros | Sapere.it</span></a>, su <span style="font-style:italic;">sapere.it</span>. <small>URL consultato il 30 marzo 2021</small>.</cite></span> </li> <li id="cite_note-4"><a href="#cite_ref-4"><b>^</b></a> <span class="reference-text"> <cite class="citation web" style="font-style:normal">(<span style="font-weight:bolder;
