hellohello.
for those of you who still don't know:
sapphic poetry means poetry written by lesbians/ about lesbians.
that is a very broad definition.
it is not, however, (necessarily) the literary equivalent of soft porn.
as you can see from some of the poets i've mentioned below.

sapphic poetry can also refer to poems written in sapphic meter
which (presumably?) are not necessarily lesbian poems.

sappho herself was a famous female poet who lived on the isle of lesbos (greece).
should explain where the words come from. =)

this is the probably the best site online for finding such poetry.
apart from sappho herself, these are some well-known poets who may have written verses classified as sapphic/ lesbian:
christina rossetti ("pulse for pulse, breath for breath", "who has seen the wind? neither you nor i. but when the trees bow down their heads, the wind is passing by.")
amy lowell ("i pour my heart and watch it burn")
emily dickinson ("to make a prairie")
charlotte mew ("hurt not the trees")

do note that these poets were not necessarily lesbian.
also, that you don't have to condone sapphic verse for it to exist.

but anyway =) even if we don't do this for litday it should be an interesting read.
