Noah Built His Altar and Philo Asked Which God He Was Thanking
After the flood, Noah sacrificed to Elohim, not to Adonai. Philo of Alexandria thought the choice of divine name was the whole point of the story.

The First Thing He Did on Dry Ground
The water had covered everything for a year. The raven had gone and not returned. The dove had gone and come back with an olive branch, and then gone again and not returned. The ground was dry. Noah opened the ark's door and stepped out.
The first thing he did was build an altar.
He took clean animals, clean birds, and offered burnt offerings on the altar. The smell of it went up, and the text says God smelled the pleasing aroma and said in His heart that He would never again curse the ground for humanity's sake. The rainbow followed. The covenant followed. The entire post-flood world emerged from the smoke of that one altar.
The question Philo of Alexandria asked is easy to miss in the drama of the rainbow: Noah built the altar to which God?
The Name He Used
In Hebrew, the divine name used in the altar passage is Elohim, not the Tetragrammaton pronounced as Adonai. These are not interchangeable. Elohim is the universal name, the one associated with God as creator and judge of all existence, the God who governs nature and nations and the general order of things. Adonai is the covenantal name, the one associated with the particular relationship between God and the Jewish people, the name of promise and intimacy and specific history.
Noah had just been saved from a flood in which all other human life was destroyed. His survival was as particular and personal a divine act as anything in Genesis. And he offered his gratitude to the universal name, the distant one, the name that belongs to no people specifically.
Why?
The Two Kinds of Gratitude
Philo's answer, in the text attributed to him, turns on a distinction between two modes of thanksgiving. The first is voluntary, spontaneous, the immediate overflow of a heart that has received something and cannot stay silent. This gratitude is complete in itself. It asks nothing, promises nothing, arrives before any formal structure shapes it.
The second kind of gratitude is what Philo calls obligated: the thanksgiving that comes from having understood intellectually what you have received, having traced the implications, having recognized the specific character of the divine action that spared you. This is the gratitude of reflection rather than reflex.
Noah's offering to Elohim was the first kind. It was not calculated. It was not the offering of a man who had fully worked out what had just happened to him. It was the offering of a man who stepped off a boat onto dry ground after a year on the water and built a fire before he could think. The universal name was the name you used when your gratitude was bigger than any particular relationship, when what you were grateful for was existence itself.
What the Name Withheld
Philo's reading implies something significant about what Noah was not yet ready to do. To offer to Adonai, the covenantal name, would have required Noah to understand himself as standing within a particular relationship with a God who had chosen him for a particular purpose. That understanding was coming. The covenant and the rainbow and the specific prohibitions of the Noahide laws were about to arrive.
But in the moment he built the altar, Noah was not yet in the covenant. He was simply alive. He was a man who had carried eight people and a world of animals through a year of water and had come out the other side. The offering he made was the offering of someone who did not yet know what name to use for what had saved him, only that something had, and that something deserved an altar.
The covenant would teach him the name. The altar came first.
