There’s just one today: The portrait of Monsieur Lavoisier and his wife, painted Jacques-Louis David in 1788. It has been liked and reblogged about twenty times within a few hours. This was one of my first posts, made on the very day I joined Tumblr, and it has enjoyed continuous popularity.

At length their long kiss severed, with sweet smart:
And as the last slow sudden drops are shed
From sparkling eaves when all the storm has fled,
So singly flagged the pulses of each heart.

Their bosoms sundered, with the opening start
Of married flowers to either side outspread
From the knit stem; yet still their mouths, burnt red,
Fawned on each other where they lay apart.

Sleep sank them lower than the tide of dreams,
And their dreams watched them sink, and slid away.
Slowly their souls swam up again, through gleams

Of watered light and dull drowned waifs of day;
Till from some wonder of new woods and streams
He woke, and wondered more: for there she lay.

— Dante Gabriel Rossetti, written before 1862, first published 1870.
