We will review the era’s political and religious context, and then parse Renaissance Latin

Mary Stuart departed Scotland age six. She returned to Scotland in 1561 a French king’s widow and Catholic, age 19. In 13 years of absence, Catholic Scotland had embraced Protestantism. Can Mary navigate her way through protestant Scotland?

In 1561, Elizabeth had been queen three years. England was gripped with fear. A Stuart queen with French allies may place her yet on the English throne. The claim was through her mother Margaret; elder sister to King Henry VIII. English soldiers were sent north and joined rebel protestant Scots. The campaign was inept. But diplomacy won for England what arms failed to do; the Treaty of Edinburg removed the French. Scotland had a Protestant church and a Protestant council. Mary Stuart did not sign the treaty

The assumption is the question posed was in Latin. Elizabeth replied in kind as courtesy demands. Further, the remainder of the quote we have this date was probably a longer sentence, with two ending phrases

Buchanan and Haddon, are referred to by their Latinized names, Buchananus and Haddonus. Each poet is the direct object of their respective phrase, Buchananum and Haddonum

Now, let us look at each phrase’s verb. Elizabeth uses the same verb for both phrases; pono is a third conjugation, transitive verb. The verb’s sense is; I put or I place. However, Elizabeth adds a twist to the verb’s sense, she used a prefix

Using the same verb, each with its own prefix, shades the sense with each phrase having equal weight and respect. Haddonus is English and Protestant and Buchananus is Scottish and Catholic (later adopting Protestantism). Each man wrote congratulatory poetry; Haddon wished Princess Elizabeth recovery from illness and Buchanan praised Mary Stuart in anticipation of her marriage

Finally, each phrase has a middle word, omnis is a third-declension adjective acting as an adverb, omnibus is in the plural with the sense; all. nemo is a pronoun, with the sense; nobody or no one. The pronoun is acting adverbially

The trick is equilibrium of the body politic. Here is a translation of the Queen’s speech…
