<p>diagram from  Bodleian Library Michael MS. 276, entitled <i>Clavicolo di Salomone Re d'Israel figlio de David</i>, an Italian language version of the "Key of Solomon" grimoire.
</p><p>It is a variant of the "<b>Sigillum Aemeth</b>" published in Athanasius Kircher's Oedipus Aegyptiacus (Rome, 1652-4, pp. 479-81.) 
</p><p>The figure is accompanied with the following caption (in the translation of S. Liddell MacGregor Mathers 1889):
</p><p><i>This is the general pentacle, called the<b> Great (or Grand) Pentacle</b></i>
</p>
<i>It should be written on sheepskin paper or virgin parchment, the which paper should be tinted green. The circle with the 72 divine letters should be red or the letters may be gold. The letters within the pentacle should be the same red, or sky blue everywhere, with the great name of God in gold. It serves to convene all spirits; when shown to them they will bow and obey you.</i>
