Can a painting make you question your entire existence? A toothy skull w/ a wig + flowers sits atop an upper-body laden with pearls. An olive branch tucked in the figure’s white garment has attracted the attention of a bird. This “vanitas” painting was meant to inspire the contemplation of death.

The @romtoronto.bsky.social captured me looking very excited about 16th century Flemish oil paintings last night (I was most likely laughing at the fact that we decided the royal nepo baby child depicted behind me looked, and I quote, "very punchable").

The @romtoronto.bsky.social invited me to the gala opening of their new painting exhibition, "Saints, Sinners, Lovers, and Fools" and I immediately found my new bestie. If anyone can find me his rooster hat, please know I will pay handsomely for it.
