The Blytt-Sernander classification, or sequence, is a series of north European climatic periods or phases based on the study of Danish peat bogs by Axel Blytt (1876) and Rutger Sernander (1908). The classification was incorporated into a sequence of pollen zones later defined by Lennart von Post, one of the founders of palynology.
Layers in peat were first noticed by Heinrich Dau in 1829. A prize was offered by the Royal Danish Academy of Sciences and Letters to anyone who could explain them. Blytt hypothesized that the darker layers were deposited in drier times; the lighter, in moister times, applying his terms Atlantic (warm, moist) and Boreal (cool, dry). In 1926 C.A. Weber noticed the sharp boundary horizons, or grenzhorizont, in German peat, which matched Blytt’s classification. Sernander defined subboreal and subatlantic periods, as well as the late glacial periods. Other scientists have since added other information.
The classification was devised before the development of more accurate dating methods, such as C-14 dating and oxygen isotope ratio cycles. Currently geologists working in different regions are studying sea levels, peat bogs and ice core samples by a variety of methods, with a view toward further verifying and refining the Blytt-Sernander sequence. They find a general correspondence across Eurasia and North America.
Come inside I'll show you my life,
My personal hell that you have made.
Twisted brain you've poison eyes,
Buried in your pretty face.
You've burned down a part of me,
Maybe better now this way.
Beware! The time's now closer,
The time has come for you to pay.
Poison Eyes.
Staring down a thousand cries
Sinfull Eyes.
Vomiting a hundred lies
Time to pay my beloved one,
Now your sins tears you apart.
Bloody dreams in haze you're lost,
Your heart is pounding in the cold.
Magic flames your soul they shatter,
I'm the wizard the spell caster
The time is coming meet your doom
Come and face the endless gloom
Poison Eyes.
Staring down a thousand cries
Sinfull Eyes.
Vomiting a hundred lies
Die for your sins,
Cry for your life,
Pay for my dreams,
Pray now it's time.
Come to me and feel me
And all those tears I've been
Shedding for you all those years
I've been lonely.
Winds of despair
Blow strong tonight
Shattering my life
A lifetime of lies
Desire now burning
Desire now burning
Desire now burning
