The Masonic term "Plus Ultra" ("more beyond") appears on a banner between two pillars (representing Masonry) in an emblem from Whitney's Choice of Emblems (1586). (Bacon is said to have published this book.) The emblem also depicts arches (another Masonic symbol) and the light and dark "A"s which symbolize Athena. The same light and dark "A"s appear on the title page of the King James Bible.
The following is from Mather Walker on the subject
While Francis Bacon was in France during the period from 1576 through 1579 a number of works were published exhibiting his handiwork. The above device, which also appeared in Alciat's Emblems, published in 1577, is most important because, in it, Bacon devised a key for those works he later wrote, the most prominent of which, were the Shake-Speare Plays.
This emblem merits the most exacting scrutiny. The first fact, which is sounded loud enough to make the deaf wince, is that Bacon takes the most extraordinary measures to signal his identity. There is the boar from his coat of arms. A careful examination of the right side of the device reveals, near the top, an "F" lying on its front; and, further down, a "B" lying on its back. At the top of the device one sees the Pillars of Hercules with the words, "Plus Oltre". "From the most able to him that can but spell", every school child, knows this was a stock idea of Bacon's. In the center of the device is a pyramid, another of Bacon's stock ideas. In the "Wisdom of The Ancients" he describes Pan, whom, he says, represents nature:
On both faces of the
pyramid appear the letter "A", pointing to another stock idea of
Bacon's: The Alphabet of
With Bacon's identity established, one need only ask: what information was the device designed to transmit?
The first item of information, highly significant in itself, is that is that the light "A", dark "A" emblem is a device of Bacon's. The second relates to the passage in the "Masculine Birth of Time", written about the same time the Alciat emblem book was published, where Bacon says:
On the right side of the device is what appears to be old ruins. The pillars with the legend "Plus Oltre" are to the left of the device. In view of the passage quoted from the "Masculine Birth of Time" it is evident that Bacon denotes Antiquity, by the dark "A", (hence the ancient ruins on that side of the device) and Anticipations, or the light of nature of the future (symbolized by the Gates of Hercules with the legend "Plus Oltre"), by the light "A."
Another stock metaphor is his Intellectual Globe. Ancient knowledge is symbolized by the Old World around the Mediterranean sea. The New World, symbolizing future knowledge, is west of the Pillars of Hercules, which, according to legend stood at the western most limit to the Mediterranean Sea. In connection with this, compass convention would be as follows:
More than a dozen light "A", dark "A" headpieces are found on Elizabethan literature which appears under the name of various authors. These include Edmund Spenser, Christopher Marlowe, Shakespeare, and others: all authors believed by Baconians to be among the various masks used by Francis Bacon. On these headpieces the light "A" is almost always to the left, and the dark "A" to the right.The third item of information is that the Alphabet of Nature is composed of two equal and directly opposing aspects.
The boar in the emblem was used in Bacon's first crest, but was later replaced with the boar image below, which is also seen in the Novum Organum of 1620.
"Emblems bring down intellectual to sensible
things for what is sensible always strikes the memory stronger."

All these elements connect Bacon
