Verdana is a humanist sans-serif typeface designed by Matthew Carter for Microsoft Corporation, with hand-hinting done by Tom Rickner, then at Monotype. Demand for such a typeface was recognized by Virginia Howlett of Microsoft's typography group. The name "Verdana" is based on a mix of verdant (something green, as in the Seattle area and the Evergreen state, Washington), and Ana (the name of Howlett's eldest daughter).

A trebuchet or trebucket is a siege engine that was employed in the Middle Ages either to smash masonry walls or to throw projectiles over them. It is sometimes called a “counterweight trebuchet” or "counterpoise trebuchet" in order to distinguish it from an earlier weapon that has come to be called the “traction trebuchet”, the original version with pulling men instead of a counterweight.
