Na fasadi hemijskog instituta Tehnickog univerziteta u Braujnsvajgu u Nemackoj nalazi se ovaj neobicni trodimenzionalni skup slova i simbola.





Autor fotografije, Florian Hardwig, pise da su ovde predstavljeni (al)hemijski simboli pet metala: zlata, gvozdja, bakra, olova i srebra, iz cetiri razlicita vremenska perioda, 15, 16, 18 i 19. veka.

On jos kaze:

Seven metals were assigned to celestial bodies, colors, parts of the human body, and days of the week:


Gold → Sun ☉ → golden yellow → left hand → Sunday
Silver → Moon ☽ → blue → left foot → Monday
Iron → Mars ♂ → red → right hand → Tuesday
Quicksilver → Mercury ☿ → white → head → Wednesday
Tin → Jupiter ♃ → grey → side → Thursday

U+2609 SUN ☉ (and U+263C WHITE SUN WITH RAYS ☼)
U+2642 MALE SIGN ♂
U+2640 FEMALE SIGN ♀
