The logo

Omnia sol temperat
purus et subtilis,
novo mundo reserat
faciem Aprilis,
ad amorem properat
animus herilis
et iocundis imperat
deus puerilis.

The sun warms everything,
pure and gentle,
once again it reveals to the world
April's face,
the soul of man
is urged towards love
and joys are governed
by the boy-god.

April the second month of the ancient Roman, and the fourth of the modern calendar, containing thirty days. The origin of the name is uncertain. The traditional etymology is Lat. aperire, "to open", in allusion to its being the season in which trees and flowers begin to "open". Therefore, the logo shows a blooming flower. Moreover, the logo shows a blooming "Camellia japonica - 'April Remembered'", i.e. an "April" in April. This reflects that APrIL II is the follow-up of the assessment project APrIL I. Thus:
