Dali's painting is surreal, so unconventional. A melting clock, wet cats flying through the air, hippopotamus horns, and nudes with dirty feet...his range of subjects and presentations are beyond imagining.
Gala, his wife, was in many of his paintings. He just adored her. Even though she had numerous affairs, their marriage stood the test of time. She often helped him paint floating items by holding them up in the air while he painted.
Dali returned to the Catholic Church after years of rejecting, searching and questioning. I like that faith was so important to him that it drove him to want to know more and more. His paintings contain many religious icons: the Christian fish, angels, halos, rhinos, the cross of Christ, and Madonnas. He wanted a scientific understanding of the Virgin birth. (Don't we all!) He even wrote the Pope asking for such an explanation but never received an answer. One of his paintings included an ostrich egg because it has the ability to hatch on its own without need for warmth from the mother's body. He used it to represent the Virgin birth...a birth without need of human fertilization.
You can just go anywhere in your mind with his paintings. If you haven't viewed any of them in awhile I encourage you to take a look and try and see his thought processes. Better yet, get a book that explains them. I surely couldn't get it on my own! Way too weird for me. The painting below is said to be his most famous.
