Plutarch provided the plots for a couple of Shakespeare's plays, and his stories also provided Shakespeare with a number of allusions.
Shakespeare did not use the word "indecent" although he did use "decent". The word "lewd" might be the word he would choose to express this idea.
He used many allusions to Shakespeare's work in his everyday conversations.
James H. Sims has written: 'Dramatic uses of biblical allusions in Marlowe and Shakespeare'
The couple was arrested for lewd behavior in public. His novels were condemned by the church as lewd and immoral.
Nothing--the Puritans were against theatre and when they got control of the country they banned it. Instead of watching lewd entertainments like Shakespeare plays, they went to church and listened to very long sermons for free.
Some allusions in "The Once and Future King" include references to Arthurian legends, Greek mythology, and Shakespeare's works. For example, the character of Merlin alludes to the wizard Merlin from the King Arthur stories, while the character of Lancelot alludes to the Greek hero Lancelot. Additionally, White's retelling of the Arthurian legend often mirrors themes found in Shakespeare's plays such as "Hamlet" and "King Lear."
Lasciviousness means lewd and lustful.
Shakespeare does occasionally quote his sources in his work. For example, the Latin phrase "Et tu, Brute?" in Julius Caesar comes from Plutarch. There is no particular name for these quotations. References in Shakespeare to other works of literature or to mythology, which are usually the names of characters and not quotations, are called allusions. That term is not specific to Shakespeare: any reference to an outside source within a work is called an allusion. It's kind of like the modern term "Easter Egg" only allusions are more up front.
Most stories, particularly classical ones, have allusions and references to Christian stories or Greek myths, even though they are not always aware of this. Many common sayings or phrases have roots in Greek mythology that people aren't aware of. Shakespeare in particular used many allusions to various Greek myths.
Lewd music is one with indecent or crude lyrics
