The messenger bird from Cambyses came early one morning around the first week of November, but at that time Alexander was blissfully asleep.
And he only got around to reading it midday.
The reason for this was that the previous night was especially grand, where Ptolomy made sure to show that the events this year were not at all in any way smaller in scale than the previous years so as to show off his prestige and grandeur.
So Alexander returned to his room pretty late.
And given that soon afterward a blizzard overtook the city, the cold outside weather and the snug, warm room made Alexander sleep in to the point he skipped breakfast and woke up only before lunch.
And as evidence of how horrid the weather was outside, even waking so late, Alexander still found his room to be dark and even a bit damp, courtesy of the raging snowstorm that was still going on.
