‘Nothing more deceptive than an obvious fact—’
fabrications masquerading as oracles in sage tunics.
Beware of accepting wooden nickels as change,
certainty— a mirage drifting in a sandstorm.
A gnomic poem is a four-line verse/stanza with aphorisms and sayings in one line which are then described or embellished in the proceeding lines. Here, the first and third lines are sayings you may have heard before (with a bit of poetic license from ‘yours truly’). Lines two and four are their embellishments.
