A version of the <a href="https://en.wikipedia.org/wiki/Shield_of_the_Trinity" class="extiw" title="en:Shield of the Trinity">Shield of the Trinity</a> diagram painted on the ceiling of Landa church, Halland, Sweden in 1804.<a rel="nofollow" class="external autonumber" href="http://www.svenskakyrkan.se/landa/?item=203">[1]</a>  The central node includes the letters of  the Hebrew tetragrammaton YHWH.  The three links connecting the three outer nodes include trinitarian doctrinal affirmations (<i>Tre äro ett</i> "Three are one", <i>ett äro tre</i> "one is three", <i>och de tre äro ett</i> "and the three are one") -- rather than words with the meaning "is not" (which are usually included in these positions in other versions of the "Shield of the Trinity" diagram).
