In this tetrahedron: one face, the Beauty, one face the Truth, one face the Goodness, one face you have to figure out by yourself, is not visible here. :-)
So, related to this:
Happy birthday, J., Divine proportionate angelic tetrahedron. :-D
And related to that, (read with attention! hihi, notice the triangle water-air-earth, but also, fire, and the last element):
My heart is like a singing birdChristina Rosetti, "A Birthday".
Whose nest is in a water'd shoot;
My heart is like an apple-tree
Whose boughs are bent with thickset fruit;
My heart is like a rainbow shell
That paddles in a halcyon sea;
My heart is gladder than all these
Because my love is come to me.
Raise me a dais of silk and down;
Hang it with vair and purple dyes;
Carve it in doves and pomegranates,
And peacocks with a hundred eyes;
Work it in gold and silver grapes,
In leaves and silver fleurs-de-lys;
Because the birthday of my life
Is come, my love is come to me.
