Viriditas is a
Latin word with origins that go back to ancient times.
This writeup explores some of the past and present uses of the word.
The
Oxford Latin Dictionary associates
viriditas with
Cicero,
Pliny and
Apuleius who used it to mean
green vegetation,
verdure and
greenery.
Webster's 1913 Dictionary's
reports that viriditas is the Latin form of
viridity. It provides two definitions of viridity:
- Greenness; verdure; the color of grass and foliage.
- Freshness; soundness.
Hildegard von Bingen's Viriditas
About 900 years ago,
Hildegard von Bingen (1098-1179) used
viriditas to describe the
principle of
greenness or
vitality in all of nature.
Although this could be interpreted to mean the process of
life in a natural sense, Hildegard meant it to
encompass the
spiritual perspective as well.
In this sense,
viriditas refers to the power or influence of
God over life and nature.
Hildegard von Bingen is credited with composing a number of Gregorian chants including
"O nobilissima viriditas" (O most noble greening power) and
"O viriditas digiti Dei" (O Life-green finger of God) which explore the concept of viriditas in nature and in theology respectively.
Kim Stanley Robinson's use of Viriditas
Science fiction author
Kim Stanley Robinson (1952-) used
viriditas in his
Mars trilogy (
Red Mars,
Green Mars and
Blue Mars) to refer to the greening process which is transforming
Mars into a planet teeming with
life.
It is is primarily associated with Hiroko, a very influential personality within the
Greens.
The Reds and the Greens of Mars
One of the key conflicts in the
trilogy is between the
Reds who believe that Mars should be preserved in as
pristine a condition as possible and the
Greens who believe that Mars should be transformed into planet supporting life in all its forms (including
human life without the need for artificial life support systems).
In a really well managed juxtaposition that runs throughout the trilogy, the Reds of Mars act a lot like the most extreme environmentalists or preservationists on Earth today (the term "Mars huggers" comes to mind) and the Greens of Mars are the exact opposite - i.e. willing to accept and encourage all manner of disruption to the planet in order to further their cause of greening Mars.
Coryphaeschna viriditas
Coryphaeschna viriditas or
Mangrove Darner is a species of
dragonfly which is found in the very southeast tip of the U.S. State of
Florida.
It is in the
Aeshnidae family within the
order Odanata.
The species was first described by Calvert in 1952.
For the trivia fans out there, the other three members of the Coryphaeschna genus are Coryphaeschna Adnexa, Coryphaeschna Ingens and Coryphaeschna Luteipennis.
